Bulletin 1489-M Thermal-magnetic Circuit Breakers are UL 489 Listed for branch circuit protection in the United States and Canada, and they are certified as Miniature Circuit Breakers for IEC applications. These circuit breakers are ideal for extreme ambient conditions, feature fast breaking time, and superior shock and vibration resis...
Bulletin 1492-GH and 1492-GS High-density Miniature Circuit Breakers are thermal-magnetic type supplementary overcurrent protective devices. Our single-pole, high-density miniature circuit breakers incorporate a thermal portion and a magnetic trip function for the combined advantages of two sensing systems.
Our Bulletin 1492-MC Thermal-magnetic Miniature Circuit Breakers are general-purpose devices suitable for the majority of industrial, inverse time circuit breaker applications. They combine thermal and magnetic trip actions and provide accurate overload and short-circuit protection for conductors and connected equipment.
