The Siemens 5SM3348-6 is a SENTRON residual current circuit breaker (RCCB), 4-pole, type A, rated 100 A with 30 mA sensitivity at 400 V AC. It's an instantaneous-trip device — no intentional delay — so it clears ground faults as fast as the waveform allows.
Snaps onto standard DIN rail (REG). Depth is 77 mm, installation depth 70 mm. IP20 with the distribution board installed and conductors connected; that's typical for enclosed panel gear, not for open-bay exposure.
It's a 4-pole residual current circuit breaker (RCCB) for 400 V AC, 50 Hz systems. Rated 100 A with 30 mA sensitivity, type A (pulsating DC and AC residual currents). Used for ground-fault protection in distribution boards.
Rated current 100 A, sensitivity 30 mA, voltage 400 V AC, 50 Hz. Short-circuit current rating 10 kA. 4 poles, instantaneous trip. Power loss 8.9 W per pole at rated current in hot state.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time.
