Product details

The C25B6TM160 is a ComPacT NSX250B frame molded-case circuit breaker with a 160 A TM-D thermal-magnetic trip unit, 4 poles, rated for distribution duty per EN/IEC 60947-2. At 415 V the breaking capacity drops to 25 kA Icu, and at 440 V to 20 kA Icu; that derating curve is standard for MCCBs and means you size the breaker to the actual line-to-line voltage at the fault point, not the system nominal.

Deployment context

The IP40 front face and IK07 impact resistance are adequate for enclosed panel installation; if the breaker lives in a washdown zone or outdoors, it needs a separate enclosure.

Frequently asked questions

What is the breaking capacity of C25B6TM160 at 415 V?

The C25B6TM160 delivers 25 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, which is the standard rating for a 415 V distribution feeder in most industrial panels.

Where can I buy C25B6TM160 and how is it quoted?

The C25B6TM160 is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — no stock or price figures are published here.
