Abstract

323,789. British Thomson-Houston Co., Ltd., and Heath, H. C. Sept. 10, 1928. Controllers with no-volt and overload release. - A circuitbreaker 2, with an underload release 1, supplying a motor, has the release 1 short circuited by a thermal device 4 upon the occurrence of overload conditions. The device 4 may be operated by the current passing through the circuit-breaker.
