Product details

The C10B4TM100C is a Schneider Electric ComPacT NSX100B circuit breaker, a 4-pole unit rated 100 A at 50 °C with a TM-D thermal-magnetic trip unit. It sits in the ComPacT NSX family, designed for distribution applications where a compact footprint and high breaking capacity are needed.

Breaking capacity and trip unit

Breaking capacity is rated 40 kA Icu at 240 V AC, 25 kA at 415 V AC, and 20 kA at 440 V AC — the 415 V figure is the one most panel builders will size against for European 400 V networks. Neutral protection is set at 1 x Ir (4D), meaning the neutral pole tracks the phase protection at full rating.

IP40 protection (IK07 impact) suits indoor panel installation; no additional enclosure needed for basic dust and finger protection.
