Product details

The Schneider Electric C10W35E040 is a ComPacT NSX100HB2 molded-case circuit breaker, 3-pole, with a MicroLogic 5.2 E electronic trip unit rated 40 A at 40 °C. The electronic trip unit provides LSI protection (long-time overload, short-time short-circuit, instantaneous) plus energy metering, demand current/power, and time-stamped event logs, so it doubles as a panel-level power monitor.

Where it is used and deployment context

The 105 mm width, 161 mm height, and 86 mm depth fit a typical MCCB slot in a multi-breaker lineup.

The MicroLogic 5.2 E trip unit offers adjustable long-time pickup (Ir), long-time delay (tr), short-time pickup (Isd) and delay (tsd), and instantaneous pickup (Ii). This allows selective coordination with downstream breakers — the 20-minute thermal memory before and after tripping prevents nuisance re-closure on hot conductors.
