Product details

The Schneider Electric C11E3TM050B is a ComPacT NSXm 3-pole (3P) moulded-case circuit breaker rated 50 A at 40 °C, fitted with a TM-D thermal-magnetic trip unit.

Above that temperature, the thermal element derates — standard IEC 60947-2 practice. The breaker is utilisation category A, meaning it is not intended for frequent switching of motor starts — it is a distribution breaker, not a motor-protective device. Power dissipation per pole is 4.6 W, totalling 13.8 W for the 3-pole assembly. That matters for enclosure thermal rise calculations when grouping several breakers in a sealed panel. IP40 front-face protection and IK07 impact resistance handle typical industrial panel environments — dust ingress is limited, but it is not rated for washdown. Mounting is via backplate (not DIN rail), with horizontal or vertical orientation allowed. The 9-module pitch (81 mm wide, 137 mm high, 80 mm deep) occupies standard cabinet cutout spacing. Connection is front-face only, using compression lugs or busbars at a 35 mm pitch with spreaders, or 27 mm without.

Frequently asked questions

What is the breaking capacity of C11E3TM050B?

The breaking capacity is 16 kA at 415 V AC, performance level E. This is the maximum fault current the breaker can safely interrupt at that voltage.

What standards does C11E3TM050B comply with?

It is certified to EN/IEC 60947-2, the standard for low-voltage switchgear and controlgear. It is also suitable for isolation per that standard.

Where can I buy C11E3TM050B?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at the time of quote.
