Product details

The Schneider Electric C25V4TM160 is a ComPacT NSX circuit breaker with a TM-D thermal-magnetic trip unit rated 160 A at 40 °C. Four poles, 85 kA Icu at 500 V AC — that's the short-circuit capacity that determines if this breaker clears a fault without welding or rupturing. It's built to EN/IEC 60947-2, the standard for low-voltage switchgear in industrial distribution.

Breaking capacity and trip unit

At 690 V AC it still holds 75 kA — that's the HB1 breaking capacity code. The TM-D trip unit provides thermal overload (L) and magnetic short-circuit (I) protection; no earth-leakage module built in.

Mounts on a backplate — horizontal or vertical, flat against the panel. IP40 enclosure protection keeps out tools and wires over 1 mm, but not water; this is for indoor panel use, not washdown.

Frequently asked questions

Where can I buy C25V4TM160 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What is C25V4TM160's breaking capacity at 690 V?

75 kA Icu at 660/690 V AC 50/60 Hz per IEC 60947-2. The breaking capacity code is HB1.

What compliance documentation does Schneider provide for C25V4TM160?

The breaker is certified to EN/IEC 60947-2. It carries an IP40 rating per IEC 60529 and IK07 impact protection per IEC 62262.
