The Siemens SENTRON 5SU1354-1RC06 is a 2-pole (1P+N) RCBO rated at 6 A with a C tripping characteristic and 30 mA Type AC residual current protection. It snaps onto a DIN rail in a distribution board — 2 modular width units (36 mm wide) — and accepts supply from either top or bottom. The C curve handles moderate inrush from motorized or capacitive loads without nuisance tripping, while the 30 mA residual element covers personnel protection in final circuits.
Breaking capacity and selectivity
Rated breaking capacity is 10 kA per EN 60898 and 35 kA per IEC 60947-2. The 35 kA figure under IEC 60947-2 means this RCBO can interrupt high prospective fault currents typical in industrial panelboards — useful where the upstream transformer is close. The 10 kA EN 60898 rating covers the residential and commercial installation standard. Overvoltage category III and pollution degree 2 suit fixed-installation distribution boards.
Environmental range and mounting
Ambient temperature range spans -40 °C to 75 °C, so it works in unconditioned enclosures or cold storage areas. IP20 with connected conductors — standard for enclosed distribution boards. Mounting position is any orientation, which simplifies panel layout. Depth is 70 mm, height 90 mm, width 36 mm (2 MW).
