Product details

The 25 A thermal-magnetic trip unit (TM-D) gives instantaneous magnetic pickup on short-circuit and a thermal element for overload protection. Category A utilisation means it is not intended for cascading with downstream breakers on selective coordination — plan for full discrimination at the device level.

Mounts on a backplate (flat on the back), horizontal or vertical orientation. Width is 108 mm (12 x 9 mm pitches), depth 80 mm, height 137 mm. Connection terminals accept compression lugs or busbars; front-connect both upstream and downstream.

The C11N4TM025B is listed as current-production (active lifecycle stage). No end-of-life notice or successor order code is recorded.

Frequently asked questions

What is the breaking capacity of C11N4TM025B?

50 kA at 415 V AC (performance level N), which is the maximum short-circuit current the breaker can safely interrupt at that voltage.

Where can I buy C11N4TM025B?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
