Product details

The C25B32D160 is a Schneider Electric ComPacT NSX moulded-case circuit breaker on the NSX250B frame, three-pole, with a MicroLogic 2.2 electronic trip unit rated 160 A at 40 °C.

Coordination and duty cycle

Rated for distribution duty (Category A, not a motor-protector curve), so it coordinates downstream with other NSX breakers or fuses in a selective scheme. Electrical endurance is 20 000 cycles at 440 V at half rated current, 10 000 cycles at full rated current — enough for a main feeder in a panel that sees a few operations per day, not a switching duty cycle. Mechanical endurance is 20 000 cycles. The IK07 impact rating and IP40 front face mean it survives a tool drop in the enclosure and keeps dust out of the toggle mechanism.

Front-connect terminals top and bottom, 35 mm connection pitch. Five accessory slots accept shunt trips, auxiliary contacts, or a motor mechanism without removing the breaker.

Frequently asked questions

Where can I buy C25B32D160 and how do I get a price?

The C25B32D160 is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ to confirm current availability and pricing at quote time.

What is C25B32D160's breaking capacity at 415 V AC?

25 kA Icu at 380/415 V AC 50/60 Hz conforming to IEC 60947-2.

What compliance documentation does this brand provide for C25B32D160?

The breaker is certified to EN/IEC 60947-2, suitable for isolation per that standard, and carries an IP40 front face and IK07 impact rating. Specific RoHS/REACH/UL documentation should be confirmed from the manufacturer's product certificate for the exact variant.
