A relay includes a fixed terminal, a fixed contact connected to the fixed terminal, a movable contact piece facing the fixed terminal, a movable contact, a drive unit including a coil and an armature operated by electromagnetic force generated from the coil, a card, and a wall disposed between the armature and the card. The movable contact is connected to the movable contact piece and faces the fixed contact. The card is disposed between the drive unit and the movable contact piece, and transmits an operation of the armature to the movable contact piece. The card includes a card body, a contact part, and a protrusion. The card body is disposed between the wall and a movable contact piece. The contact part extends from the card body toward the armature. The protrusion protrudes from the card body toward the wall and is disposed on a side of the contact part.

A system and method for an automatic transfer switch comprising a fixed contact (26), a first oscillating rod (16) communicatively and operatively connected to a first movable contact (25), a second oscillating rod (18) communicatively and operatively connected to a second movable contact (27), a link rod (12) communicatively and operable connected to the first and second oscillating rods (16, 18), a guide plate (20), and a permanent magnetic actuator (2) comprising a first end and a second end communicatively and operatively connected to the link rod (12) via a third oscillating rod (8), wherein the first end being energized independently of the second end. The automatic transfer switch is operable to position the guide plate (20) based at least on a permanent magnetic force applied to the first end or the second end of the permanent magnetic actuator.

This disclosure relates to various embodiments of lockout relay devices. In one embodiment, a lockout relay device may transition between a closed position and a lockout position in response to an action of a deck device. The lockout relay may further be configured to transition from the lockout position to the closed position only in response to one of a manual adjustment and a reset operation. A manual actuator may permit a manual transition of the lockout relay device from the closed position to the lockout position and from the lockout position to the closed position. The lockout relay device may remain in the lockout position until the occurrence of one of a manual adjustment and a reset operation.

A switch for an electrical circuit includes a base, a rotatable cam having a first profile and a second profile, a solenoid, a link, and a member comprising a cam follower configured to follow the second profile. A first cycle of the solenoid includes a first energized state and a first de-energized state and the second cycle of the solenoid includes a second energized state and a second de-energized state. A first portion of the link couples to the solenoid, and a second portion of the link movably couples to the first profile of the cam. When the solenoid is in a first cycle, the member moves from a retracted position to an extended position, and when the solenoid is in a second cycle, the member moves from the extended position to the retracted position.

A circuit breaker tripping mechanism providing relatively low instantaneous level tripping is disclosed. Circuit breaker tripping mechanism includes an armature with a first portion extending in a first direction from an armature pivot and a second portion extending in a second direction from the armature pivot, and a magnetic field generator configured as part of a line conductor. Magnetic field generator is operable to produce a magnetic field acting upon the second portion during a short circuit. Circuit breakers including the circuit breaker tripping mechanism and methods of tripping a circuit breaker are provided, as are other aspects.
