[Also in Division H1] A bi-metal tripping element for an automatic circuit breaker has a thin wire heating coil attached to it by a coating of synthetic resin. The coil may be bifilar wound to bring both ends of the wire to the same end of the bi-metal or one end of the coil may be connected to the bi-metal which then serves as a lead; part of the heating may be due to the current in the bi-metal.
