Product details

Built to EN/IEC 60947-2, with suitability for isolation marked on the device. The TM-D trip unit combines a thermal bimetal for overload protection and a magnetic coil for short-circuit protection — no electronics, no adjustment. For distribution duty (Category A), it's a fixed-trip, no-selectivity breaker sized for a 40 A feeder.

Breaking capacity and deployment

Front connection top and bottom, terminals accept compression lugs or busbars. 108 mm wide, 137 mm high, 80 mm deep; 12 module pitches at 9 mm. IK07 impact rating handles light knocks during installation.

Frequently asked questions

What is the breaking capacity of C11E4TM040B?

16 kA at 415 V AC, performance level E per IEC 60947-2. That is the maximum prospective fault current it can safely interrupt at that voltage.

What trip unit does C11E4TM040B use?

A TM-D thermal-magnetic trip unit rated 40 A at 40 °C. Fixed, non-interchangeable — overload protection via bimetal, short-circuit via magnetic coil.

Where can I buy C11E4TM040B?

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