The 4.5 kA interrupting rating at 400 V AC is the fault current it can safely clear; verify the available fault current at the installation point does not exceed that. The 2-pole construction switches both line conductors, suited for 230/400 V single-phase or two-phase loads where full isolation is needed. Occupies 2 modular width units (36 mm) on standard 35 mm DIN rail. Depth 76 mm, height 90 mm, installation depth 70 mm. Mounting position any; sealable for tamper-proof applications. Halogen-free and silicon-free construction — suitable for environments with sensitive electronics or strict fire-load requirements. Rated per EN 60898 for breaking capacity. Overvoltage category III, degree of pollution 2. Energy limitation class 3. Touch protection provided. Suitable for residential buildings and infrastructure installations per the manufacturer's designation.","metaTitle":"Siemens 5SL3216-7MB SENTRON MCB, 2P C 16A 4.5kA 400V","metaDescription":"Siemens 5SL3216-7MB SENTRON miniature circuit breaker, 2-pole, C-curve, 16 A, 4.5 kA at 400 V AC.
