Product details

The C25N4TM160 is a Schneider Electric ComPacT NSX250N moulded-case circuit breaker (MCCB) with a 4-pole (4P) configuration, rated 160 A at 40 °C. The 50 kA Icu at 415 V AC (breaking capacity code N) means it can safely interrupt a fault current up to 50,000 A at that voltage without failing — that is the standard rating for most 400 V distribution boards in Europe and Asia. At 240 V AC the Icu jumps to 85 kA (UL), and at 690 V AC it drops to 10 kA; the 415 V figure is the one that governs fit for a typical 400 V line. The TM-D trip unit is fixed thermal-magnetic — no interchangeable electronic modules, no earth-leakage add-on.

Mounts to a backplate (not DIN rail) in either horizontal or vertical orientation. Rated IP40 (finger-safe front), IK07 impact resistance.

Frequently asked questions

Where can I buy C25N4TM160 and how do I get a price?

The C25N4TM160 is sourced to order against an RFQ through independent distribution. Submit a request for quote (RFQ) to confirm current availability and pricing — no stock or price figures are published here.

What is C25N4TM160's breaking capacity at 415 V?

The C25N4TM160 is rated 50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, which is the standard breaking capacity for this frame size (NSX250N) at typical 400 V distribution voltages.
