Title:
THERMAL OVERLOAD RELAY
Document Type and Number:
WIPO Patent Application WO/2024/042746
Kind Code:
A1
Abstract:
In the present invention, a trip operation of a reversal mechanism (24) is performed by a differential lever (23) being pivoted by being pushed against a push shifter (22a) from the outside in the radial direction with a position at which the differential lever engages with a pull shifter (22b) as the pivot center, and a compensation bimetal contact surface (74) that is provided to the differential lever displacing a compensation bimetal (31). In addition, there is provided a compensation bimetal displacement amplifying means that amplifies the displacement of the compensation bimetal by, in an overloaded state in which an overcurrent flows, stopping of the displacement of the pull shifter and a subsequent displacement of the push shifter, whereby the differential lever is pivoted.
