Abstract
A trip unit (release unit) for a power circuit breaker or a protective switch, in particular as an undervoltage trip device which interacts with the switch drive mechanism in such a manner that, if the voltage is not sufficient, the trip unit unlatches the switch drive mechanism immediately, the trip unit having a trip coil 21, which is designed as a plunger-type armature coil and has a trip plunger 20 which is prestressed in the trip direction 30 by means of a compression spring and is inserted in a magnetic store housing, the end 2 of an arm 1b of a clamping lever 1, which is designed as a rocker, being pressed (during opening of the switch or when the locking mechanism is open) by a compression spring 5 into a cutout 32 which is located in a control cam 31 of the switch, such that the other arm 1a of the clamping lever 1 rotates the trip lever 12 in such a manner that the trip lever 12 is pivoted about its shaft 13 and, in consequence, presses the trip plunger 20 into the magnetic store housing 21. <IMAGE>
