Product details

The C10N4TM040C is a Schneider Electric ComPacT NSX100N circuit breaker with a 40 A thermal-magnetic trip unit (TM-D) in a 4-pole (4P) configuration. The TM-D unit provides L (thermal) overload protection and I (magnetic) short-circuit protection, both adjustable via the trip unit dials. Breaking capacity is what determines whether this breaker can clear a fault without welding its contacts. At 220/240 V AC it handles 90 kA; at 690 V AC it drops to 10 kA. The 'N' breaking capacity code (50 kA at 415 V) sits between the standard 'S' (36 kA) and 'H' (70 kA) tiers in the NSX family. The 161 mm height, 140 mm width, and 86 mm depth fit the standard ComPacT NSX cutout.

Mechanical durability is rated at 50,000 cycles — the number of on-off operations the mechanism can perform before wear exceeds spec. Electrical durability varies with load: 50,000 cycles at 440 V at half rated current (In/2), 30,000 cycles at full In, and 10,000 cycles at 690 V at full In.

Overvoltage category III suits fixed-installation distribution boards. IK07 impact resistance and IP40 ingress protection cover normal handling and panel-side contamination.

Frequently asked questions

What is the breaking capacity of C10N4TM040C at 415 V?

The C10N4TM040C delivers 50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2. This is the 'N' breaking capacity code in the ComPacT NSX family.

What trip unit does this breaker use?

It uses a TM-D thermal-magnetic trip unit rated 40 A at 50 °C. The 'L' protection (thermal) handles overloads; the 'I' protection (magnetic) handles short-circuits. Both are adjustable.

What compliance documentation does Schneider provide for C10N4TM040C?

The breaker is certified to EN/IEC 60947-2, with suitability for isolation confirmed. Pollution degree 3 per IEC 60664-1, overvoltage category III, and IP40/IK07 enclosure ratings are documented. RoHS and REACH declarations are standard for the ComPacT NSX range.
