Toggle switches and circuit breakers come together

Edited by the Electronicstalk editorial team Apr 24, 2008

Magnetic circuit breakers operate quicker than thermal units and are less sensitive to changes in ambient temperature.

The E-T-A 8345 series of single- and multipole combined toggle switches and magnetic circuit breakers is now available in the UK from Aerco.

With a current rating from 0.1 to 125A, which is 25A above the industry norm, at up to 240V AC or 110V DC, these compact breakers have a proven design, are highly robust and have a fast and accurate switching performance.

Suitable for rack, panel or plug-in mounting in telecommunication equipment, the rail industry, heavy-duty vehicles and other applications where a high degree of protection is required in a small package, these magnetic circuit breakers operate quicker than thermal units and are less sensitive to changes in ambient temperature.

Magnetic/hydraulic versions are available that have a slower reaction time and are therefore less susceptible to transient current variations.

The combination of switch and circuit breaker saves installation time, reduces component count and saves space.

In addition, a separate trip coil enables the main contacts to be opened by a remote sensor or logic control circuit such as the E-T-A X8345-R remote, motor driven on/off actuator that can be operated by a suitable external change-over switch.

Fully approved to UL489, UL1077 and EN 60934 standards, the type 8345 also carries VDE, UL, CSA and CE approvals.

Different mounting methods, toggle colours and water-splash covers are available.
