The 72 mm width (4 modular units) fits standard panel cutouts. IP20 protection applies once the distribution board is installed and conductors connected — not rated for open-panel exposure to dust or moisture. Silicon-free construction suits environments where outgassing must be avoided (e.g., adjacent to sensitive contacts or coatings). ## Thermal Derating & Ambient Limits Rated 25 A continuously from 40 °C up to 60 °C ambient. At 65 °C it derates to 23.3 A; at 70 °C to 17.6 A. The I²t withstand of 58 000 A²·s gives the let-through energy the device can survive under fault conditions. ## Installation & Wiring Notes The installation depth is 70 mm — verify enclosure internal depth before panel layout. Overvoltage category III (distribution-board level). The 0.8 kA rated conditional short-circuit current per EN 60898 and IEC 61008-1 applies when backed by an upstream overcurrent device of that rating. For testing equipment, minimum supply voltage is 195 V.","metaTitle":"Siemens 5SV4342-0KL SENTRON RCCB, 4-Pole, 25 A, 30 mA, Type","metaDescription":"Siemens 5SV4342-0KL SENTRON 4-pole RCCB, 25 A rated, 30 mA trip, Type AC, 10 kA SCCR.
