摘要:
A circuit breaker having a movable contact arm (120, 675) for opening and closing the circuit which is controlled separately by a circuit breaker mechanism for circuit protection (140) and by a switch lever (160, 660) mechanism which does not require actuation of the circuit breaker mechanism to function. The switch lever (160, 660) may also be activated remotely by a remote actuator (180, 680), for example, a solenoid. A manual reset mechanism is provided so that, actuation of which, when power has been lost to the remote actuator (180, 680) when the remote actuator (180, 680) is in the off position, moves the remote actuator (180, 680) to the on position, thereby resetting the circuit to the closed state.

A D/C trip assembly for a circuit breaker is provided. The D/C trip assembly includes a magnet, a mounting assembly and an armature assembly. The mounting assembly includes a body, the mounting assembly body including a pivotal coupling. The armature assembly includes a magnetic body and a trip bar linkage, the trip bar linkage extending from the armature assembly body. The armature assembly body is structured to move between a first position, wherein the armature assembly body is close to the magnet, and a second position, wherein the armature assembly body is spaced from the magnet. The trip bar linkage is structured to move between a first position and a second position, the trip bar linkage positions corresponding to the armature assembly body positions. The trip bar linkage is structured to be coupled to a trip bar.

A trip unit (202) for use with a circuit protection device (104) including a trip mechanism (210) includes a support bracket (302) and a magnet member (304) coupled to the support bracket. The magnet member is configured to emit a magnetic field when a current is transmitted through the trip mechanism. The magnet member includes a first side portion (402), a second side portion (404), and a rear portion (406) coupled between the first side portion and the second side portion. The trip unit also includes a pivot arm (306) pivotally coupled to the support bracket. The pivot arm includes a first end (602), a second end (604), and a curved portion (606) coupled to the first end and the second end. The pivot arm is configured to pivot towards the magnet member to cause the trip mechanism to interrupt the current when the current exceeds a first threshold.
摘要:
The invention relates to an electromagnetic actuator comprising a magnetic circuit consisting of a stationary magnetic armature and a blade, said blade being movable in opposition to a spring and capable of moving a mechanical actuating member, and an induction coil arranged about an arm of the armature, the assembly being inserted into a housing from which the mechanical member extends. The housing comprises a through-slot located inside a magnetic circuit, in which through-slot the coil is wound once the housing is closed.
