Product details

The Schneider Electric C11F3TM050B is a ComPacT NSXm 3-pole moulded-case circuit breaker rated 50 A at 40 °C with a TM-D thermal-magnetic trip unit. It carries a 36 kA interrupting capacity at 415 V AC (performance level F), which means it can safely clear a bolted fault up to that level without upstream cascading — sized for distribution panels where the available fault current sits in the 36 kA range. The TM-D trip combines a thermal bimetal for overload protection and a magnetic coil for short-circuit response; no earth-leakage module is integrated.

The 81 mm width occupies 9 module pitches on a standard DIN-rail profile. IP40 front face and IK07 impact resistance handle typical enclosure environments — not washdown-rated, but fine for indoor distribution boards where dust and tool drops are the main concern.

Frequently asked questions

What are the key ratings of C11F3TM050B?

3-pole, 50 A at 40 °C, thermal-magnetic TM-D trip, 36 kA interrupting capacity at 415 V AC, IP40, suitable for isolation per IEC 60947-2.

Where can I buy C11F3TM050B and how is it quoted?

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

What compliance documentation does Schneider provide for C11F3TM050B?

The breaker is certified to EN/IEC 60947-2 and carries a suitability-for-isolation mark per that standard. Pollution degree 3 per IEC 60664-1 is also listed. RoHS, REACH, UL, and other declarations are typically available from Schneider's documentation portal for the ComPacT NSXm series.
