Product details

160 A thermal-magnetic breaker, 50 kA at 415 V — ComPacT NSX250N frame

Its breaking capacity is 50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, with a symmetrical rating of 90 kA Icu at 220/240 V AC and 10 kA Icu at 660/690 V AC. The NSX250N frame carries the N breaking capacity code — the standard 50 kA at 415 V tier for distribution panels where fault levels are moderate but not extreme.

The TM-D trip unit provides thermal protection (overload, L) and magnetic protection (short-circuit, I) with fixed settings — no adjustment dials, which simplifies specification but means the breaker is matched to the load at order time.

The 105 mm width per pole (315 mm total for 3P) fits standard ComPacT NSX cutouts. IP40 front face protection keeps tools and fingers out; IK07 impact resistance handles incidental contact during panel work.

Frequently asked questions

What is the breaking capacity of C25N3TM160C at 415 V?

50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, which is the N breaking capacity code for the NSX250N frame.

Where can I buy C25N3TM160C and how is it quoted?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quote.

What compliance documentation does Schneider provide for C25N3TM160C?

The breaker is certified to EN/IEC 60947-2 and carries suitability for isolation per that standard. Pollution degree 3 per IEC 60664-1 and IK07/IP40 protection ratings are documented. Specific RoHS, REACH, or UL documentation should be requested at quote time as the evidence does not list those marks.
