Title:
CIRCUIT BREAKER AND THERMAL TRIP
Document Type and Number:
WIPO Patent Application WO/2006/103722
Kind Code:
A1
Abstract:
A thermal trip comprises a bimetal (2) having one acting end (21) and the other cantilevered fixed end (22) secured to a heater (1) serving as a fixed terminal. The acting end (21) of the bimetal (2) bends as the bimetal is heated when the heater (1) is electrified. The thermal trip is characterized in that a temperature measuring member (7) is coupled integrally with the secured portion (221) of the bimetal (2) secured to the heater (1) and exposed from the bimetal (2) and the heater (1) so that the temperature measuring member (7) can touch a contact temperature sensor (8).
