Description

The The invention relates to a manually operated circuit breaker with a rotatable about an axis hand control knob and a pluggable, replaceable add-on module, with the circuit breaker on Has locking means for locking the additional module, which between an unlocking position and a locking position movable is.

Modular constructed circuit breakers of this type are known in the art. In this case, the removal of the modules in the on state by causes mechanical locks.

The DE 10 2006 020 702 A1 discloses a circuit breaker for motor protection or power protection. This circuit breaker is modularly expandable by attaching replaceable add-on modules. In this case, this circuit breaker may have a locking device that block the pulling of the control unit at the ON position of the circuit breaker.

The DE 36 42 719 A1 discloses a hand-operated circuit breaker according to the modular system. The rotatable hand control knob locks in the on state, the modular trip block against removal from the circuit breaker housing.

Around electronically monitor the known switchgear can, is the need given status information about the lock or the state of the circuit breaker electronically to pass on central monitoring units.

It It is therefore an object of the invention to provide an electronic status message the lock or the switching state of an additional module to produce a circuit breaker.

According to the invention the object is achieved by a device according to claim 1. Advantageous embodiments of the device result from the dependent claims.

The The invention relates to a manually operated circuit breaker with a rotatable about an axis hand control knob and a pluggable, replaceable add-on module, with the circuit breaker on Has locking means for locking the additional module, which between an unlocking position and a locking position movable is and is characterized in that the position of the blocking means by a power transmission member to a microswitch is transmitted in the additional module such that the micro-switch switched on in dependence on the position of the blocking means or off. Through the microswitch is an electronic Circuit affects which status information to a connected Can transmit evaluation system. By use a power transmission member, the location of the microswitch be varied accordingly in the additional module.

It has proved to be particularly advantageous that the blocking agent is rotatably mounted on a shaft and the power transmission member is operatively connected to the blocking means via a control groove. It is possible to adjust the cam groove so that the power transmission member is addressed only from a certain point in time. Thus is a fine adjustment of the response of the microswitch in Dependence on the position of the blocking means possible. Advantageously, the shaft of the locking means is directly connected to the Axis of the rotary hand control knob operatively connected. That has the advantage that when pressing the manual control knob of the switching device at the same time the removal of the additional module prevented from the switching device in the on state becomes.

A Particularly preferred embodiment of the invention sees before that the force transmission member one around an axis rotatable in the additional module mounted rocker switch and a first End and having a second end, wherein the rocker switch with the first end is guided in the control groove of the blocking means, when the locking means between the unlocking position and the Locking position is rotated, and the rocker switch with the second end to an actuating pin of the microswitch is applied. The advantage here is the very space-saving design the power transmission between the locking means and the microswitch.

A further, particularly advantageous embodiment of the invention provides that the cam groove has a cam, the at a rotation of the locking means a displacement of the first end the rocker switch causes, and the rocker switch so around the rotatable Axle tilts that the second end of the rocker switch the actuating pin of the microswitch actuated. By the design of the control cam can the response of the microswitch depending on be influenced by the position of the blocking agent. It can the On time or off time can be changed by appropriate Elevations or depressions inserted into the control curve become.

Further Advantages, special features and expedient further education The invention will become apparent from the dependent claims and the following description of preferred embodiments based on the pictures.

From the pictures shows:

1 a perspective view of a circuit breaker according to the invention with additional module;

2 a schematic view of a circuit breaker according to the invention with additional module in the open state;

3 a schematic view of a circuit breaker according to the invention with additional module in the on state;

4 a perspective view of the locking means with the power transmission member in the unlocked state;

5 a perspective view of the locking means with the power transmission member in the locked and off state;

6 a perspective view of the locking means with the power transmission member in the locked and on state.

1 shows a circuit breaker according to the invention 1 with an additional module 2 , which is placed on the circuit breaker housing. The additional module 2 For example, it may be an electronic or mechanical trip module which, when adjustable parameters are reached, provides the circuit breaker 1 to turn off. The parameters can be, for example, the temperature of a motor to be switched or the current flow through the motor connections. The circuit breaker 1 has a hand control knob 11 on, with the circuit breaker 1 can be switched on and off. 2 and 3 show schematically a circuit breaker according to the invention 1 with an additional module 2 , The additional module 2 is in a receptacle of the circuit breaker 1 used and has a micro switch 3 with an actuating pin 31 on. Furthermore, located in the additional module designed as a rocker power transmission member 4 , The rocker switch 4 is on an axis 43 rotatably mounted. A first end 41 the rocker switch 4 protrudes from the additional module 2 out. A second end 42 is located on the actuating pin 31 of the microswitch 3 at. A movement at the first end 41 the rocker switch leads to an opposite movement of the second end 42 the rocker switch. A blocking agent 13 is about a wave 12 with the hand control knob 11 connected. Will the manual control knob 11 turned, the blocking means rotates 13 in an opening of the additional module 2 into it. The additional module 2 can not get out of the switching device 1 be removed when the hand control knob 11 is turned on. On the blocking agent 13 is a tax good 14 brought in. In the control groove 14 will be the first end 41 the rocker switch 4 guided. Will the manual control knob 11 turned to the ON position, the first end engages 41 the rocker switch 4 in the rudder groove 14 and is moved. This tilts the rocker switch 4 over the axis 43 and the second end 42 pushes the actuating pin 31 in the microswitch 3 , The microswitch 3 is turned on and can pass a signal to a bus via an electronic circuit, not shown. The wave 12 can also be independent of the manual control knob 11 be rotated to allow coupling with other controls. The tax good 14 has a control cam 15 on which the first end 41 the rocker switch 4 leads. In this case, different switching times by wave peaks or valleys in the control curve 15 will be realized.

The 4 to 6 show an embodiment of the switching rocker according to the invention 4 with the corresponding corresponding blocking means 13 and microswitches 3 , 4 shows the locking means with the rocker switch 4 in the unlocked and not switched-on state. The first end 41 the rocker switch 4 is in accordance with 5 not yet in the tax box 14 , The blocking agent 13 is already in the opening of the add-on module 2 retracted and prevents the removal of the additional module 2 from the switching device 1 , The microswitch 3 is not yet actuated because the cam 15 the first end 41 the rocker switch 4 has not moved yet. Will the blocking agent 13 further rotated, causes the cam 15 a shift of the first end 41 the rocker switch 4 what to impress the actuating pin 31 through the second end 42 the rocker switch 4 leads. The microswitch 3 is on.

Other embodiments are conceivable in which the microswitch 3 is arranged such that it is turned off in the on state of the additional module.

This requires the position of the microswitch 3 concerning the second end 42 the rocker switch 4 be turned around.

Instead of a rotating locking device 13 can also be a translationally movable locking means 13 be provided, which via a pin, which serves as a power transmission member 4 acts on the microswitch 3 acts.
