The 3-pole configuration (3P) switches all three phases simultaneously, so a fault on any one phase opens the whole circuit. Single-phase operation is rated at 250 V AC, and the DC rating is 72 V — useful for DC sub-circuits in mixed panels. Mechanical endurance is 10,000 switching cycles — adequate for panel isolation duty where it's cycled a few times a year. ## Physical fit and mounting Width is 18 mm (1 modular unit per pole, so 3 modules wide for the 3-pole unit). ## Construction and compliance details Halogen-free and silicon-free construction, sealable for tamper-proofing in metered installations. Touch protection is built in. Pollution degree 2, overvoltage category III — suitable for fixed-installation downstream of the service entrance.","metaTitle":"Siemens 5SL4308-7RC SENTRON MCB, 3P C 8A 10kA","metaDescription":"Siemens 5SL4308-7RC SENTRON miniature circuit breaker, 3-pole, C-curve, 8A, 10kA breaking capacity per EN 60898.
