Product details

Integrator note — 50 A ComPacT NSX with TM-D trip

The Schneider C10V4TM050 is a ComPacT NSX circuit breaker with a 50 A TM-D thermal-magnetic trip unit, 4 poles, and toggle control. Its 85 kA Icu at 500 V AC (75 kA at 690 V) means it can interrupt high fault currents on a distribution board without upstream coordination issues — the HB1 breaking capacity code tells you it's the high-break version of the NSX100 frame. The 161 x 140 x 86 mm footprint and front-front connections (upside and downside) simplify busbar and cable routing in a fixed-panel layout.

Compliance documentation per EN/IEC 60947-2 is available; the breaker carries an IK07 impact rating and IP40 enclosure protection for panel-mount use. Electrical durability is specified per IEC 60947-2: 20,000 cycles at 440 V In/2, 10,000 at full In, and 5,000 at 690 V In. That's standard for a molded-case breaker in distribution duty — not a motor-switching device, but adequate for a panel main or feeder that sees infrequent operation.

Frequently asked questions

What is C10V4TM050's breaking capacity at 500 V?

85 kA Icu at 500 V AC 50/60 Hz per IEC 60947-2. At 690 V it's 75 kA Icu, and at 525 V it's 80 kA Icu.

What compliance documentation does Schneider provide for C10V4TM050?

The breaker is certified to EN/IEC 60947-2 and carries an IK07 impact rating per IEC 62262 and IP40 protection per IEC 60529. Suitability for isolation is confirmed per the same standard. RoHS/REACH declarations are typically available from Schneider's documentation portal.
