Product details

The C11F6TM050B is a Schneider Electric ComPacT NSXm 63F frame circuit breaker, 4-pole, rated 50 A at 40 °C with a TM-D thermal-magnetic trip unit. The 4-pole configuration with neutral left suits three-phase plus neutral distribution, common in commercial and light industrial switchboards.

At 108 mm wide × 137 mm high × 80 mm deep (12 module pitches of 9 mm), it fits standard distribution board cutouts.

Electrical durability is 20,000 cycles at 440 V In/2, 10,000 cycles at 440 V In, and 5,000 cycles at 690 V In; mechanical durability 20,000 cycles. That's enough for normal switching duty but not for frequent motor-starting — it's a distribution breaker, not a motor-circuit protector. Operating altitude 2000 m without derating, 5000 m with derating. Relative humidity 0–95%.

Frequently asked questions

Where can I buy C11F6TM050B?

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

What is C11F6TM050B's interrupting rating?

The breaker has a performance level F, meaning 36 kA interrupting capacity at 415 V AC per IEC 60947-2.

What is the closest alternative to C11F6TM050B?

Within the ComPacT NSXm family, the closest alternative would be a different trip rating (e.g., 63 A) or a different pole count (3P instead of 4P). No pin-compatible drop-in with identical ratings exists; the TM-D trip unit and frame size are specific to the 50 A 4P variant.
