Product details

The C10B6TM050 is a Schneider Electric ComPacT NSX100B circuit breaker with a 50 A thermal-magnetic TM-D trip unit, 4 poles, and a 25 kA breaking capacity at 415 V AC (Icu per IEC 60947-2). The thermal-magnetic trip gives you L (overload) and I (short-circuit) protection in one unit; no separate relay to wire. At 50 A and 40 °C ambient, it's a straight fit for a 50 A feeder or a moderate motor branch circuit, though motor starting duty needs a check on the magnetic pickup vs inrush.

Mounts on a backplate — flat on the back, horizontal or vertical orientation — with front connections top and bottom. Neutral is on the left; the toggle control is manual, no motor operator by default.

Frequently asked questions

What is C10B6TM050's breaking capacity at 415 V?

25 kA Icu at 380/415 V AC 50/60 Hz conforming to IEC 60947-2. At 220/240 V it reaches 40 kA Icu; at 440 V it drops to 20 kA Icu.

What compliance documentation does this brand provide for C10B6TM050?

The breaker carries EN/IEC 60947-2 certification, suitability for isolation per that standard, and IP40 / IK07 mechanical impact protection. Pollution degree 3 per IEC 60664-1, overvoltage category III. Specific RoHS/REACH/UL declarations would be confirmed at quote time through the supply channel.

Where can I buy C10B6TM050 and how is it quoted?
