Rated 230/240 V AC at 50 Hz, it carries a B-curve tripping characteristic (instantaneous trip between 3 and 5 times rated current) and a 30 mA residual-current sensitivity of type AC — meaning it detects sinusoidal AC fault currents only, not pulsating DC or smooth DC. That makes it a fit for general-purpose socket-outlet circuits, lighting, and small appliance loads where no variable-speed drives or electronic loads are downstream. ## Temperature derating — the real-world current rating The 10 A nominal rating only holds at 30 °C ambient inside the enclosure. At 40 °C it's 9.5 A; at 50 °C it's 9 A; at 60 °C it's 8.5 A; at 70 °C it's 8 A. The full derating curve is published for every 5 °C step from 30 °C to 70 °C. At 36 mm wide (2 modular units), it occupies two standard 18 mm positions. Depth is 77 mm, installation depth 70 mm — check your enclosure's internal clearance if you're retrofitting into a shallow gland-plate area. Supply can enter from top or bottom; the neutral is switched (1P+N, not 2P). IP20 protection applies only when the distribution board is installed with connected conductors — the busbar stabs and terminals are live when the front cover is off, so standard finger-safe terminal shrouds or a dead-front enclosure are expected. ## Compliance and approvals","metaTitle":"Siemens 5SU1656-0KK10 SENTRON RCBO, B-Curve 10A 30mA, 6kA","metaDescription":"Siemens 5SU1656-0KK10 SENTRON RCBO, 2-pole 1P+N, B-curve 10A, 30mA residual current type AC. 6kA breaking capacity per EN 60898, 15kA per IEC 60947-2.
