Abstract
A method for manufacturing a trip unit that connects to a circuit breaker. The method includes mounting an assembly formed by a shaft and a trip member in a first case, mounting a detecting member in a second case, and assembling the first case and the second case, a contact end cooperating mechanically with the trip member such that the trip member trips the circuit breaker in the assembled configuration of the trip unit when the corresponding detecting member detects an electric fault.
Claims13
A method for manufacturing a trip unit that connects to a circuit breaker, said trip unit comprising:
- a first block comprising:
- a first case including two walls, each wall comprising a through orifice for receiving a shaft;
- and
- a trip member of the circuit breaker mechanically connected to the shaft and accessible from outside the first case;
- and
- a second block comprising a second case and at least one detecting member for detecting an electric fault, each detecting member being positioned inside the second case and including at least one moving element comprising a contact end, that is movable toward the trip member, when the respective detecting member detects the electric fault,
- wherein the method comprises:
- a) mounting an assembly formed by the shaft and the trip member in the first case;
- b) mounting the at least one detecting member in the second case;
- and
- c) assembling the first case and the second case, the contact end cooperating mechanically with the trip member such that the trip member trips the circuit breaker in the assembled configuration of the trip unit when the corresponding detecting member detects the electric fault.
