Multiphase motor thermal protection relays having two separate container forming container with sealable cover etched channels sliding with break mechanism single container held allowing different functions second container.

摘要

The thermal protection relay has bimetallic sections (22) for overheating. There are contact slabs (16 to 19) sliding in etched channels in an upper container opening two contacts away from a swinging section (24). The contactor has two separate container (1,15) combined to form a monoblock container with a sealable cover with the current breaking mechanism regrouped in one container and able to operate with another thermal relay having a different function.
