Product details

Generator-duty trip unit, 80 A

The C103MG080 is a TM-G thermal-magnetic trip unit from the ComPacT NSX100...250 family, rated 80 A at 40 °C and built to EN/IEC 60947-2. It is the generator-protection variant — the 'G' suffix means the magnetic trip curve is shaped for the inrush and fault characteristics of generator feeds, not standard distribution loads. Three poles protected (3D), fixed mount, no earth-leakage module.

Long-time pickup (Ir) is adjustable from 0.7 to 1.0 x In (56–80 A), so you can dial it down to match a slightly smaller generator nameplate. The instantaneous magnetic trip is fixed at 200 A, which on a generator circuit avoids nuisance tripping on the higher magnetizing inrush typical of generator step-up transformers.

Panel and integration notes

Fits the ComPacT NSX100...250 fixed-mount breaker frame. Three-pole, 3D protected poles — all three poles have thermal and magnetic elements. IP40 front face.

Frequently asked questions

Where can I buy C103MG080 and get current pricing?

The C103MG080 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead-time commitment.

What is C103MG080 used for?

It is a thermal-magnetic trip unit designed for generator protection in ComPacT NSX100...250 circuit breakers. The TM-G curve handles generator inrush and fault characteristics, making it the correct choice for generator output feeders, backup-power panels, and genset switchboards.

What standards does C103MG080 comply with?

It is certified to EN/IEC 60947-2 (low-voltage switchgear and controlgear — circuit-breakers). Pollution degree 3 per IEC 60947-1. Electrical shock protection Class II. IP40 front face per IEC 60529.
