Definitions
- E R SA TZBLATT Floating bearing is safely avoided.
- The. Current supply in the contact area is also used due to its U-shaped course to quickly drive the arc that arises during the shutdown by blowing action away from the contact zone into the quenching chamber.
- the current supply in the arc guide plate and in the movable contact is used due to the opposite direction of the current to spin the movable contact away from the arc guide plate and away from the fixed contact regardless of the magnetic release in the event of a short circuit.
- the leg distance of the U-shaped blow loop is maintained during the shutdown, so that the arc drive does not decrease, in contrast to known designs.
- the counter-moment of the contact spring is reduced by the rotation of the movable contact.
- FIG. 2 shows the switched-off state with the isolating web 16 between the movable and fixed contacts.
- the current runs with closed contacts along the arrows drawn from the terminal 12 on the arc guide rail 5 and the bearing 11, the movable contact 4 to the fixed contact 3 and from there via the coil of the overcurrent release 7 to the terminal 10.
- the movable contact 4 is flung away from the fixed contact 3 and the current is interrupted.
- the movable contact 4 goes into the position shown in FIG. 2, the arc drawn between the movable contact and the fixed contact jumping over from the movable contact to the arc guide rail 5 after reaching the open position. Due to the blowing effect of the power supply lines, the arc is driven into the quenching sheet stack and extinguished there.
