    摘要: A low cost thermally-actuated circuit breaker, adapted to be miniaturized. In one embodiment, the device has a spring arm on a base which combines as an integral unit the arm itself, an electrical contact, a manual reset member, and a terminal; a thermostat metal blade also mounted on the base and incorporating integrally an electrical contact and terminal structure; the blade engaging the end of the spring arm in such manner that the force of the arm is in a direction in which the thermal blade is relatively rigid, the spring arm and blade being held on the base by the cover for the assembly in operative position. In a second embodiment, a plurality of elements are arranged on a common base, with a common cover holding all of the elements attached to the base. In a third embodiment, indicating means are provided to indicate when one of the elements or more has tripped under overload conditions. In a fourth embodiment, the thermostat metal blade engages the spring arm by an edge portion of the blade, and the direction of the motion of the blade to open the circuit is such as to draw the edge portion in an edge-wise direction across the blade, thus reducing friction and thus stabilizing the circuit-opening characteristics of the device.

    摘要: A safety switch includes a casing having a first terminal plate having a first contact point and a second terminal plate to which an end of a bi-metal plate is connected. A second contact point is connected to the bi-metal plate. A movable member is movably engaged with the casing and has two protrusions from an inside of the movable member. The other end of the bi-metal plate is movably located between the two protrusions. The movable member can be easily connected with different types of switch members.

    摘要: A trip device for a circuit breaker comprises a first terminal; a second terminal; and a bimetal in which a slot with one side opened is formed at one end of the bimetal, the one end is divided into a first end portion and a second end portion, the first end portion is connected to the first terminal, and the second end portion is connected to the second terminal, wherein the bimetal generates heat with a current which flows between the first end portion and the second end portion, and a heating amount of the bimetal is changed based on a length of the slot. Accordingly, a desired rated current can be set, the bimetal can be prevented from being damaged by a fault current, and the fault current can be effectively detected by obtaining a sufficient amount of heat and a bending amount of the bimetal.
