100695_en_03 TMC Data sheet © PHOENIX CONTACT 2012-03-09 1D e s c r i p t i o n Single or multi-position thermomagnetic circuit breaker with lever actuation, DIN rail mounting, trip-free mechanism that cannot be influenced, various characteristic curves, all-pole 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.

5 Trigger characteristics
The thermomagnetic circuit breaker is available in 18 nominal current levels and in single and multi-pos. versions. The version with the "medium-blow (M1)" trigger characteristic is suitable for AC and DC applications. The "fast-blow (F1)" characteristic version is suitable for DC applications. The characteristic curves (see page 7) depend on the ambient temperatures. To avoid early or late disconnection, the circuit breaker nominal current must be multiplied by a factor. The characteristic curves (see page 7) are also valid for multi-position devices if all positions have an equal load. For multi-position devices and only 1-pos. overload, the thermal tripping limit changes for characteristic curves F1 and M1 to a maximum of 1.7 x IN. For DC, the magnetic operate values of the curves are around factor 1.3 higher. Tripping is supported even with high-energy current peaks < 0.003 s. In this case, the nominal current can only be led to 80%. Alternatively, the load current can be increased by a multiplication factor and the circuit breaker dimensioned accordingly. NOTE: Use a backup fuse in combination with the circuit breaker if the maximum switching current can be exceeded in the event of an error.
