The 80 A rating at 40 °C is the baseline; the device derates linearly as ambient temperature rises — 77.57 A at 45 °C, 74.59 A at 50 °C, down to 48.84 A at 70 °C. Depth is 70 mm, matching the standard installation depth for SENTRON modular devices. The supply cable can enter from the top or bottom. The IP20 rating applies when installed in a distribution board with conductors connected — standard for enclosed panels; no washdown rating. ## Compliance and approvals The device is silicon-free, which matters for applications where silicone outgassing can contaminate contacts or optics. The protection against electric shock is rated as finger and back-of-hand safe per the design standard.","metaTitle":"Siemens 5SV4347-0MB SENTRON RCCB, 4P, 80A, 30mA, Type AC","metaDescription":"Siemens 5SV4347-0MB SENTRON RCCB, 4-pole, 80 A rated at 40 °C, 30 mA trip, Type AC, 10 kA SCCR.
