Product details

The C16N6TM125 is a Schneider Electric ComPacT NSX160N circuit breaker with a thermal-magnetic TM-D trip unit rated 125 A at 40 °C. The 50 kA Icu at 415 V AC (breaking capacity code N) tells you it can safely interrupt a fault current up to 50 kA at that voltage without failing — critical for ensuring the breaker clears a short-circuit before upstream gear takes damage.

Integration notes

Mounts on a backplate (not DIN rail) in horizontal or vertical orientation. Front connections top and bottom simplify panel wiring. IP40 enclosure protection is suitable for clean indoor switchgear; IK07 impact rating handles incidental tool contact during commissioning.

Frequently asked questions

Where can I buy C16N6TM125?

The part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.

What is the breaking capacity of C16N6TM125 at 415 V?

The breaking capacity is 50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. That's the N breaking capacity code — sufficient for most industrial distribution panels with a transformer secondary fault level in that range.

What compliance documentation does Schneider provide for C16N6TM125?

The breaker is certified to EN/IEC 60947-2 and carries a suitability-for-isolation marking per that standard. UL 60947-4-1 ratings are also listed for 240 V, 480 V, and 600 V AC. For RoHS/REACH declarations, refer to the manufacturer's compliance documentation available on request.
