The C10B47E040 is a Schneider ComPacT NSX molded case circuit breaker rated 40 A continuous at 40 °C, with a 40 kA ICu breaking capacity at 440 V AC across 4 poles. It carries the MicroLogic 7.2 E electronic trip unit providing L, S, I and earth-leakage protection, plus an LCD display for metering and event logs.
How it compares
Compared to the C10F3TM025, the C10B47E040 uses 4 poles instead of 3 and delivers 40 kA ICu versus 85 kA, with a 40 A rating against 25 A. The C10F3TM025 also supports 690 V supply voltage versus 440 V. Pick the C10B47E040 when the BOM requires 4-pole distribution and 40 A continuous; the C10F3TM025 suits 3-pole, higher-fault panels at 25 A.
