The 10 kA breaking capacity per EN 60898 means it can safely interrupt a fault current up to 10,000 A at 400 V AC without welding contacts or cascading failure upstream. For multi-phase operation the maximum voltage is 440 V AC, and at DC the breaker is rated 72 V. The energy limiting class 3 (the highest per EN 60898) means it clears faults fast enough to limit let-through energy, which helps with downstream device coordination. The breaker is sealable (tamper-evident seal provision), halogen-free and silicon-free, and carries touch protection on the terminals.","metaTitle":"Siemens 5SL4363-7CC SENTRON MCB, 3P C 63A 10kA 400V","metaDescription":"Siemens 5SL4363-7CC SENTRON miniature circuit breaker, 3-pole, C-curve, 63 A, 10 kA breaking capacity at 400 V AC.
