摘要： A molded case circuit breaker includes an interlock which prevents the operating handle from being placed in the off position after the main contacts have been welded together. By preventing the operating handle from being placed in an off position during such a condition, the operating handle will indicate the correct status of the main contacts and the operator will be made aware that the main contacts are welded together.

摘要： This concerns a molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The trip unit is removable. In this case the trip unit is insertable into a trip unit region in the case of the circuit breaker from the top or end thereof. The trip unit is then joined to an internal electrical conductor by way of a bolt and an internally fixed nut. The bolt can be driven into the nut through the trip unit conductor and the internal conductor from a position external to the circuit breaker case. The trip unit can be inserted into the trip unit conductor from a point above the circuit breaker case or vise versa. The trip unit has a securement nut built into its case.

摘要： A trip unit includes a housing, a rotary plunger mounted in the housing and a pivotal trip bar also mounted therein. The trip bar latches the plunger in an on position, releases the plunger to a tripped position and re-latches the plunger. A set of springs biases the plunger to the tripped position. A rotary trip lever is pivotally mounted in the housing. A trip solenoid includes a linear plunger, which resets the solenoid when retracted, and which engages and rotates the trip lever when extended, in order to rotate the trip bar and release the rotary plunger. The rotary plunger engages the rotary trip lever when reset and rotates the same in an opposite direction, in order to retract the linear plunger and reset the solenoid. During that reset operation, the rotary plunger also cams the trip bar, in order to re-latch the rotary plunger in the on position.

摘要： This concerns a molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. Disposed within the circuit breaker casing is a region for the installation of an auxiliary device, such as a bell alarm device, shunt trip device etc. The case of the auxiliary device has an opening disposed therein through which a movable auxiliary device lever protrude. The opening of the circuit breaker case has a region for interfacing with the operating mechanism of the circuit breaker. A separate lever is disposed between the operating mechanism and the auxiliary device lever member. This separate lever member is driven by the operating mechanism of the circuit breaker and actuates the lever of the auxiliary device. It is pivoted about a protrusion on the auxiliary device.
