Its short-circuit withstand rating is 6 kA, and it carries a conditional short-circuit current rating of 0.8 kA per IEC 61008-1. The 6 kA figure governs the maximum prospective fault current the device can safely interrupt under standard conditions; the 0.8 kA conditional rating applies when the RCCB is backed by an upstream overcurrent protective device — a coordination detail that matters for selectivity studies. The device is instantaneous-acting (no intentional short-time delay), so it trips immediately on detection of residual current. Mounts on DIN rail (REG) in any orientation. Overall dimensions: 72 mm wide, 90 mm high, 70 mm deep. The 70 mm installation depth matches the standard depth of most SENTRON distribution boards — no extra enclosure depth required. This is normal for a DIN-rail device inside a closed distribution board; the IP20 rating applies only when the board is installed and conductors are connected. Operating ambient temperature range: -25 °C to +45 °C. Silicon-free construction — relevant for applications where silicone outgassing can contaminate contacts or optical surfaces. Mechanical service life is 2,000 operating cycles. For a 4-pole device at full load, total dissipation is approximately 5.2 W — a modest thermal load that does not require derating in a standard ventilated enclosure.","metaTitle":"Siemens 5SV5342-0 SENTRON RCCB, 4-pole, 25 A, 30 mA, 400 V A","metaDescription":"Siemens 5SV5342-0 SENTRON RCCB, 4-pole, Type AC, 25 A rated, 30 mA sensitivity, 400 V AC, 6 kA SCCR.
