Rated 32 A at AC with a 30 mA AC-type residual trip, B-curve tripping characteristic, and 6 kA breaking capacity per both EN 60898 and IEC 60947-2. The kit is complete: one unit, touch-protected terminals, supply feed from either top or bottom. No loose accessories to chase. ## Temperature derating — the real current limit At 40 °C the continuous current drops to 30.08 A; at 45 °C to 29.12 A; at 50 °C to 27.84 A; at 55 °C to 25.92 A. One modular width (18 mm wide, 125 mm tall, 77 mm deep, 70 mm installation depth). Mounts in any orientation on standard DIN rail. IP20 with connected conductors and distribution board installed. Halogen-free and silicon-free construction. Energy limitation class 3.","metaTitle":"Siemens 5SU9306-0KK32 SENTRON RCBO, 32 A, 30 mA, B Curve, 6","metaDescription":"Siemens 5SU9306-0KK32 SENTRON RCBO, 32 A rated, 30 mA residual current, B curve, 6 kA breaking capacity per EN 60898.
