Product details

The TM-D trip unit provides thermal overload protection (L) and magnetic short-circuit protection (I). The thermal element tracks the RMS heating of the conductor — it holds 200 A continuously but trips on a sustained overload with an inverse-time curve. The magnetic element responds instantaneously to high fault currents.

The 105 mm width and 161 mm height fit the standard ComPacT NSX cutout. IP40 front face and IK07 impact resistance handle accidental tool drops and panel dust. Five accessory slots accept shunt trips, auxiliary contacts, or under-voltage releases without increasing the footprint.

Frequently asked questions

What is the breaking capacity of C25B3TM200 at 415 V?

The breaking capacity is 25 kA Icu at 380/415 V AC 50/60 Hz conforming to IEC 60947-2, which is the standard for molded-case circuit breakers in industrial distribution.

What compliance documentation does this brand provide for C25B3TM200?

The breaker is certified to EN/IEC 60947-2 and carries suitability for isolation per that standard. Pollution degree 3 per IEC 60664-1 is specified. For specific RoHS/REACH/UL declarations, request the manufacturer's compliance documentation at quote time.

Where can I buy C25B3TM200 and how is it quoted?
