Product details

The Schneider Electric C104TM080C is a thermal-magnetic trip unit from the ComPacT NSX100...250 family, designed for fixed-mount circuit breakers in distribution applications. It provides LI protection — thermal overload (L) via a bimetallic element and magnetic short-circuit (I) via a solenoid — conforming to EN/IEC 60947-2. Rated 80 A at 50 °C ambient, the TM-D unit covers 4 poles with 4D protected poles (neutral fully protected at 1 x Ir). The long-time pickup (Ir) is adjustable from 0.7 to 1 x In, with fixed instantaneous pickup at 640 A. Network frequency is 50/60 Hz. Rated operational voltage reaches 690 V AC and 750 V DC, with pollution degree 3 per IEC 60947-1 and IP40 front-face protection.

If you hold legacy ComPacT NSX panels with TM-D trip units, this is the critical spare to secure before a failure idles the line.

Frequently asked questions

Where can I buy C104TM080C and how do I get a price?

The C104TM080C is sourced to order against an RFQ through independent distribution. Submit a request for quote (RFQ) for current availability and pricing — no stock or price figures are published for this obsolete part.

What is C104TM080C's listed range (ComPacT) on this component line?

The C104TM080C belongs to the ComPacT range, specifically the ComPacT NSX100...250 family of thermal-magnetic trip units for fixed-mount circuit breakers.

What is C104TM080C's listed standards (EN/IEC 60947-2) on this component line?

The C104TM080C conforms to EN/IEC 60947-2, the standard for low-voltage switchgear and controlgear — circuit-breakers. This certifies its performance for overload and short-circuit protection in distribution networks.
