That's the standard choice for motor-starter and lighting circuits where inrush is moderate; it avoids nuisance tripping on transformer or capacitor loads that a B-curve might catch. EN 60898 is the residential / commercial standard; the higher 20 kA rating under IEC 60947-2 means this RCBO is also rated for industrial distribution where fault currents can be stiffer. The 30 mA Type AC residual sensitivity catches sinusoidal AC earth faults — the standard for general-purpose socket-outlet and lighting circuits. It's not suitable for pulsating DC or smooth DC faults (those need Type A or Type F), so if the downstream load includes VFDs, UPS systems, or LED drivers, spec the A-type variant instead. IP20 with connected conductors is the norm for enclosed distribution boards — the RCBO itself isn't sealed against dust or moisture ingress, so it lives inside a cabinet rated for the environment. Mounts on standard DIN rail — any mounting position, supply feed from top or bottom. Depth is 70 mm, so it clears most 80 mm deep enclosures. That's the standard specification for fixed-installation distribution boards in residential and commercial settings.","metaTitle":"Siemens 5SU1354-1RC25 SENTRON RCBO, 25A, C-curve, 30mA, 10kA","metaDescription":"Siemens 5SU1354-1RC25 SENTRON RCBO, 25A rated, C characteristic, 30mA residual current, Type AC. 10kA per EN 60898, 20kA per IEC 60947-2. 2-pole, 2-module.
