Product details

ComPacT NSX with MicroLogic 5.2 E — 100 A, 100 kA at 690 V

The C25W45E100 is a Schneider Electric ComPacT NSX molded-case circuit breaker in the 4-pole (4P) form factor, fitted with a MicroLogic 5.2 E electronic trip unit. Rated 100 A at 40 °C, it delivers a full-rated 100 kA Icu breaking capacity at 690 V AC 50/60 Hz per IEC 60947-2 — meaning it can safely interrupt fault currents up to that level without upstream cascading, even on 690 V industrial mains. The 'E' designation in the trip unit adds integrated energy metering: real-time power, demand current, power quality, and time-stamped event logs accessible via the front LCD display.

The 100 kA Icu at 690 V AC is the headline figure — this breaker handles high-fault industrial environments where standard 36 kA or 50 kA units would fail. That matters for motor or transformer feeders where repeated inrush can nuisance-trip a thermal-magnetic breaker. The integrated energy meter eliminates a separate panel meter on distribution boards where per-circuit energy monitoring is required.

Integration notes

Front connections both upside and downside. Toggle control with LCD display for local status and energy data. IK07 impact resistance covers accidental tool strikes during panel maintenance.

Frequently asked questions

What is the breaking capacity of C25W45E100 at 690 V?

100 kA Icu at 660/690 V AC 50/60 Hz per IEC 60947-2. It also delivers 100 kA Icu at 500 V and 525 V AC.

Where can I buy C25W45E100 and get a price?

Sourced to order against an RFQ through independent distribution. Submit a quote request for current pricing and availability — confirmed at time of quote.

What compliance documentation does C25W45E100 carry?

Designed to EN/IEC 60947-2, pollution degree 3 per IEC 60664-1, and IK07 impact per IEC 62262. The MicroLogic 5.2 E trip unit is electronic, not thermal-magnetic.
