TRIP DEVICE FOR CIRCUIT BREAKER |
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. |
