The Siemens SENTRON 5SU1636-6FP06 is a 3-pole RCBO — a combined residual-current circuit breaker with overcurrent protection — rated 6 A, B-curve, 30 mA Type A sensitivity, and a 6 kA breaking capacity per both EN 60898 and IEC 60947-2.
The 6 kA breaking capacity (per EN 60898 and IEC 60947-2) means this RCBO can safely interrupt fault currents up to 6 kA at 400 V — enough for most sub-distribution boards where the prospective short-circuit current stays under that threshold. The 30 mA Type A residual sensitivity catches sinusoidal AC faults and pulsating DC faults — the standard for personnel protection in circuits with electronic loads (rectifiers, VFDs, LED drivers). The 400 V AC rating and 3-pole design cover three-phase loads or single-phase circuits distributed across phases.
Snaps onto DIN rail (any mounting position), with supply feed from either top or bottom. The 70 mm installation depth and 85 mm height fit standard distribution board enclosures.
