The IP20 enclosure (with connected conductors) is standard for enclosed distribution boards. ## Integration and installation notes The 5SN6350-7CN accepts solid conductors up to 25 mm², and its 70 mm installation depth fits standard distribution board depths. It is sealable and halogen-free/silicon-free — relevant for environments where outgassing or contamination is a concern. The design supports bolt-on auxiliary devices (shunt trip, alarm switch, auxiliary contact) for remote signaling or emergency-off integration. The neutral conductor is not switched by this breaker (3-pole, solid neutral). Touch protection (finger-safe terminals) is standard.","metaTitle":"Siemens SENTRON 5SN6350-7CN MCB, 3P, 50A, C-Curve, 6kA","metaDescription":"Siemens SENTRON 5SN6350-7CN miniature circuit breaker, 3-pole, 50A, C characteristic, 6kA per EN 60898, 400V AC.
