It is an instantaneous (non-time-delayed) device, meaning it trips without intentional delay on a residual fault — suited for general-purpose shock protection in residential and commercial distribution boards. Width of 36 mm (2 modular units at 18 mm per unit) and a depth of 70 mm — standard footprint that clips onto 35 mm DIN rail (REG) and occupies two positions in a 60 mm grid distribution board. ## Short-circuit and fault coordination Rated short-circuit current (Icn) of 6 kA per IEC 61008-1. In a typical domestic or light commercial board with a 63 A upstream fuse or MCB, this RCCB will withstand the let-through energy of a downstream fault without rupturing. The 0.5 kA rated conditional short-circuit current (IΔm) per IEC 61008-1 covers the residual-circuit's own withstand under fault conditions — a coordination figure, not a service rating. Overvoltage category III suits fixed-installation mains connection.","metaTitle":"Siemens 5SV5312-0 SENTRON RCCB, 2-pole, 25 A, 30 mA, 230 V A","metaDescription":"Siemens 5SV5312-0 SENTRON RCCB, 2-pole Type AC, 25 A, 30 mA, 230 V AC, 6 kA SCCR, DIN rail mount, IP20, active production.
