Schneider Electric C25N6TM200 ComPacT NSX250N 4P 200 A 50 kA TM-D Fixed Moulded Case Circuit Breaker

The Schneider Electric C25N6TM200 is a 4-pole ComPacT NSX250N moulded case circuit breaker with the neutral pole unprotected (3D), rated 200 A on a TM-D thermal-magnetic trip unit. Breaking capacity (Icu) is 50 kA at 380/415 V AC, with a 690 V AC rated operational voltage, so it suits 3-phase distribution boards with an unswitched neutral conductor.

Selection Notes

The unprotected neutral (3D) suits a distribution board where the neutral conductor is sized the same as the phases and does not need its own trip threshold, avoiding nuisance tripping on neutral imbalance. The LI trip unit gives an adjustable thermal overload (Ir, 0.7-1 x In) with an adjustable instantaneous short-circuit threshold; choose the C25N6TM200 over a protected-neutral NSX250R or NSX250HB1 variant when the installation does not require a 4th protected pole or a higher breaking capacity than 50 kA at 415 V AC.
