It's an instantaneous-trip device — no intentional time delay — so it clears ground faults as fast as the fault waveform allows. The neutral comes on the left side (N left), which lines up with the busbar arrangement in most European-style distribution boards. Feed from top or bottom; mounting orientation in any position is fine. The IP20 rating applies only after the distribution board is installed and conductors are connected — not a standalone enclosure rating. Short-circuit withstand is rated at 6 kA per IEC 61008-1, with a let-through current of 5 200 A and an I²t of 58 000 A²s. That 6 kA SCCR is typical for final-subcircuit protection in a domestic or light-commercial panel where the upstream breaker limits fault energy. The surge-current resistance is rated at 1 kA (8/20 µs waveform), and the device also passes the 0.5 kA test per IEC 61008-1 — meaning it won't nuisance-trip from a lightning surge or capacitor inrush on the line side. Operating frequency is fixed at 50 Hz.","metaTitle":"Siemens 5SV5312-6KL SENTRON RCCB, 2-pole, 25 A, 30 mA, Type","metaDescription":"Siemens SENTRON 5SV5312-6KL RCCB, 2-pole, type A, 25 A rated, 30 mA trip, 6 kA SCCR, 230 V AC.

Type A detection adds coverage for pulsating DC fault currents from electronics loads."},{"question":"Will the 5SV5312-6KL fit in a panel designed for a 5SL4363-7 MCB?","answer":"No — the 5SV5312-6KL is a 2-pole RCCB occupying 36 mm (2 MW), while the 5SL4363-7 is a 3-pole MCB at 54 mm (3 MW). They serve different functions (ground-fault protection vs overcurrent protection) and have different footprints.
