DEVICE HAVING RELAY

WIPO Patent Application WO/2005/036579

A1

A device having a relay exhibiting a reduced ratio of the operation current during an overload and that during a lock. A heater (33) is provided such that a thermo-switch part (40) is in a contact position during ordinary temperatures and in a noncontact position during high temperatures. If an excessive current flows without rotation of a motor (M) at a startup, a current flows into the heater (33) side, so that a heating of the heater (33) causes a main bimetal (21) to immediately interrupt the current. After a start of the motor (M), a conveyance of heat from a compressor turns on the thermo-switch part (40), thereby short-circuiting the heater (33) side. In this way, even if an excessive current instantaneously flows during driving of the motor, the main bimetal (21) is inhibited from being placed in the noncontact position.
