Product details

The C25F42D100 is a Schneider Electric ComPacT NSX moulded-case circuit breaker, 4-pole, rated 100 A at 40 °C with a MicroLogic 2.2 electronic trip unit. That's a standard panel layout: busbars or cable lugs come in from the front, load conductors go out the front. No DIN-rail clip here; it bolts to the panel backplate.

The breaking capacity curve is the real decision point. At 240 V AC this breaker clears 85 kA Icu; at 415 V AC it's 36 kA; at 690 V AC it drops to 8 kA. The IEC 60947-2 standard this is certified to covers exactly that: fault interruption performance for industrial circuit breakers. That's useful for repeated-start loads like compressors or conveyors.

Electrical durability: 20,000 cycles at 440 V at half rated current, 10,000 cycles at full rated current. That's typical for a distribution MCCB — not a switching contactor, but fine for infrequent on/load-off operation.

Frequently asked questions

What trip unit does C25F42D100 have?

It comes with a MicroLogic 2.2 electronic trip unit, rated 100 A at 40 °C, offering L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous short-circuit) protection.

What compliance documentation does this brand provide for C25F42D100?

The C25F42D100 is certified to EN/IEC 60947-2 and UL 60947-4-1. It carries an IP40 rating per IEC 60529 and IK07 per IEC 62262. Standard Schneider documentation includes the datasheet, installation manual, and declaration of conformity.
