Rated 20 A at 30 °C, derating to 19.5 A at 40 °C and 18.4 A at 60 °C — the thermal curve matters if the RCBO sits in a warm enclosure or next to other heat sources. The 30 mA residual trip threshold is standard for personnel protection (shock risk) per IEC 60364. Insulation voltage is 500 V, surge voltage resistance is 4 kV, overvoltage category III — suitable for fixed-installation distribution boards. Snap-on DIN rail mount, 2 MW wide (36 mm). Depth is 72 mm, installation depth 70 mm — check gland-plate clearance if the panel has a shallow back wall. Halogen-free? No — standard thermoplastic housing. This is a standard SENTRON catalog item, broadly stocked across distribution.","metaTitle":"Siemens 5SU1324-7FN20 SENTRON RCBO, 2P, 20 A, 30 mA, Type C","metaDescription":"Siemens 5SU1324-7FN20 SENTRON RCBO, 2-pole, 20 A rated, 30 mA residual current, type A, characteristic C, 10 kA breaking capacity.
