At 400 V AC the unit interrupts 50 kA; at 240 V AC it handles 100 kA, at 500 V AC 12 kA, and at 690 V AC 6 kA. That 50 kA at 400 V gives solid headroom for most industrial panel SCCR requirements — the breaker clears a fault before upstream devices need to act, which simplifies selectivity studies. The main circuit terminals accept solid conductors 2x (2.5…16 mm²) and stranded 2x (10…50 mm²) or 1x (10…70 mm²). Auxiliary and control circuits use separate screw terminals. Finger-safe touch protection (IP20 on the front) means it can sit near the panel door without an extra cover. ## Protection Functions and Environment Built-in phase failure detection trips the breaker if one phase drops out — critical for preventing single-phasing damage on a motor. No ground-fault detection onboard, so that function stays with the upstream RCD or drive. Shock rated at 25g / 11 ms. Power dissipation at rated load is 23 W (7.7 W per pole).","metaTitle":"Siemens 3RV1041-4FA10 SIRIUS Motor Circuit Breaker, 40 A, CL","metaDescription":"Siemens 3RV1041-4FA10 SIRIUS motor-protective circuit breaker, 40 A continuous, 18.5 kW at 400 V, CLASS 10 trip, 50 kA breaking capacity at 400 V.
