It's an instantaneous-trip device (no short-time delay), so it clears ground faults within one cycle — no coordination with delayed RCCBs downstream. IP20 with connected conductors in an installed distribution board — fine for enclosed panels, not for wet or dust-laden environments without an outer enclosure. ## Fault ratings and selectivity Short-circuit current rating is 6 kA per IEC 61008-1, with a conditional rating of 0.8 kA under that standard. The series fuse maximum permissible is 80 A, so if upstream protection is larger, the RCCB may not be fully coordinated under fault. Power dissipation is 2.6 W per pole in hot operating state at rated current — 10.4 W total for the 4-pole unit. That's modest, but in a tightly packed DIN-rail enclosure with multiple RCCBs, the cumulative heat can raise ambient above the 45 °C maximum. Keep ventilation paths clear. ## Installation constraints Installation depth is 70 mm, matching the unit depth. Grid spacing of 60 mm is standard for modular DIN-rail components. Silicon-free construction matters for automotive paint-shop or semiconductor fab installs where silicone outgassing causes adhesion or contamination issues. Overvoltage category III means it's rated for fixed-installation distribution level, not for downstream socket outlets.","metaTitle":"Siemens 5SV5342-6 SENTRON RCCB 25A 30mA 4P Type A","metaDescription":"Siemens SENTRON 5SV5342-6 RCCB, 4-pole Type A, 25A rated, 30mA trip, 230/400 VAC, 6kA SCCR, IP20.
