Breaking capacity is the headline here: 121 kA at 240 V, 76 kA at both 415 V and 440 V, and 53 kA at 500 V. Physical envelope: 110 mm deep, 184 mm wide, 248 mm tall. That's a standard 4-pole MCCB footprint — bolts into a panel on the mounting plate, not a DIN rail. IP40 on the front keeps tools and fingers out; no IP rating on the body sides, so clearance to live busbars inside the enclosure is on you. This is a straight thermal-magnetic breaker — wire it, torque the lugs, and it protects. The N-conductor is protected at 100% (full-rated), so it's suitable for 4-wire systems where the neutral carries load current.","metaTitle":"SENTRON 3VM1463-4GE42-0AA0 MCCB, 630 A, 4-Pole, TM220","metaDescription":"Siemens SENTRON 3VM1463-4GE42-0AA0 molded case circuit breaker, 630 A, 4-pole, TM220 release. 121 kA at 240 V, 76 kA at 415 V.
