The Siemens SENTRON 5SV4744-0 is a 4-pole residual current circuit breaker (RCCB) rated for 40 A at 50 Hz, tripping on a 500 mA residual current of Type AC. The instantaneous design (no short-time delay) clears fast, which keeps let-through energy low — the listed I²t is 58 000 A²·s.
That storage window covers handling in unheated warehouses; the operating limit is what governs the panel environment.
It is a residual current circuit breaker (RCCB) that protects against earth faults by tripping when residual current exceeds 500 mA, Type AC (sensitive to sinusoidal AC faults). Rated 40 A, 4-pole, for 50 Hz distribution boards.
40 A rated current, 500 mA trip threshold, Type AC residual, 10 kA SCCR per IEC 61008-1, 4-pole, 50 Hz, instantaneous trip, I²t 58 000 A²·s.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
