The Schneider Electric C10H34V100 is a ComPacT NSX earth leakage circuit breaker (ELCB) with a MicroLogic 4.2 electronic trip unit, rated 100 A at 40 °C. It provides overload (L), short-time short-circuit (So), instantaneous short-circuit (I), and integrated earth-leakage (R) protection in a 3-pole, 105 mm wide package for backplate mounting. The H breaking capacity code delivers 70 kA Icu at 415 V AC per IEC 60947-2, and 100 kA Icu at 240 V AC — enough headroom for most distribution panel main or feeder positions without cascading upstream.
Above that, the electronic trip unit thermally models the conductor — the 20-minute thermal memory means it remembers prior heating even after a trip resets, so re-energizing a hot circuit won't nuisance-trip on the second start. Integrated earth-leakage protection (R function) means no external RCM or toroid is needed — the MicroLogic 4.2 handles ground-fault sensing internally. The OFF position is set via the IΔn rotary switch, which lets you select the residual sensitivity without opening the cover.
Deployment context
Backplate-mounted in a distribution panel with front-facing connections top and bottom.
