Thermal magnetic circuit breakers from ETA are available in a choice of mounting options, covering an extensive range of current ratings all with high precision performance. The circuit breakers have a latching type bimetal that is combined with a magnetic coil to provide the joint benefits of delayed operation for low level over-current protection and fast magnetic action on higher value short circuits.

Thermal magnetic circuit breakers are well suited to telecommunications, process control and other industrial applications where sophisticated equipment needs correct – and dependable – protection.

Additional features include options such as auxiliary contacts for status signalling and the choice of push button or toggle manual control. There are also single, two and multi-pole models in a range of types and variants. Plug-in versions provide a convenient means of positive circuit interruption by simply removing the circuit breaker – ideal for safety critical systems during maintenance and shutdown.
