It's a 2-pole, type A device rated at 40 A and trips on a 30 mA fault current — the standard for personal protection in residential and commercial final circuits. The rated insulation voltage is 460 V, and it's built for 50 Hz systems only. ## DIN rail fit and panel space The installation depth matches the width at 70 mm, so it sits flush in a standard distribution board. Rated IP20 with conductors connected, which is the norm for enclosed panels. ## Temperature derating — real-world current capability The 40 A rating is at reference conditions. In a warm panel, it drops: at 40 °C it's 37.2 A, at 45 °C it's still 37.2 A, at 50 °C it's 36 A, at 55 °C it's 34.8 A, at 60 °C it's 34 A, at 65 °C it's 33.2 A, and at 70 °C it's 32 A.","metaTitle":"Siemens SENTRON 5SM2323-6 RC Unit, 2-Pole 40 A 30 mA Type A","metaDescription":"Siemens SENTRON 5SM2323-6 RC unit for 5SL4, 2-pole, type A, 40 A, 30 mA, 230 V AC.
