Product details

The Schneider Electric C11F6TM063B is a ComPacT NSXm moulded-case circuit breaker rated 63 A at 40 °C, with a 36 kA breaking capacity at 415 V AC. The IP40 enclosure and IK07 impact rating suit it for indoor, operator-accessible locations where accidental contact or light mechanical shock is a risk.

If your panel runs hotter, you'll need to derate — the datasheet's thermal curve governs that. Category A utilisation means it's not intended for motor starting duty — it's a distribution breaker, not a motor circuit protector.

The 108 mm width (12 module pitches at 9 mm) and 137 mm height leave a compact footprint in the panel. Connection is front-to-front (upside and downside both front), with compression lug or busbar terminals. Neutral is on the left.

Frequently asked questions

What is the breaking capacity of C11F6TM063B?

36 kA at 415 V AC, performance level F. That's the maximum fault current it can safely interrupt under IEC 60947-2.

Where can I buy the C11F6TM063B?

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