Thermal Circuit Breakers

With simple operation through the heating effect of current, thermal circuit breakers offer one of the most reliable and cost effective forms of protection device available. As a result they are ideally suited to the protection of a broad range of components and systems - from motors and transformer windings, through printed circuit boards, to the low voltage power distribution circuits of road vehicles, boats and battery powered machines.

Such applications all require the ability to discriminate between safe switch-on surges or transients on the one hand, and harmful sustained overloads on the other. Thermal circuit breakers can withstand high level surges, which arise from lamp loads or motor starting, for example. At the same time they afford protection against the effects of genuine failure such as motor locked rotors.

The characteristics of thermal CBEs can be matched closely to the ratings of the component or system they are protecting, eliminating the need for over sizing of wiring and connectors, whilst offering dependable protection - even under low level over current conditions which cannot be adequately provided for by other methods of circuit protection.
