Description

Single or multi-position thermomagnetic circuit breaker with

lever actuation, base or front mounting, trip-free mechanism

that cannot be influenced, various characteristic curves, allpole

tripping.

The circuit breakers meet the requirements of circuit

breaker standard EN 60934 (IEC 60934): S-type, TM.

Typical areas of application are telecommunications

systems, power supply units, industrial switchgear and

control systems, and rail vehicles.

The ideal characteristic curve shown here illustrates the

curve of the thermomagnetic trigger characteristic. The

time-delayed tripping protects the thermal part of the

characteristic curve against overload. The magnetic part of

the circuit breaker responds without delay to high overload

and short-circuit currents and trips within a few milliseconds.
