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.
