This breaker is dimensioned at 70 mm deep, 140 mm wide, and 158 mm tall, fitting into standard SENTRON panel cutouts and busbar arrangements. It includes 2 auxiliary switches (HQ type) and a shunt trip (STL) for remote tripping, but has no communication module, undervoltage release, phase failure detection, or ground fault monitoring — it is a straightforward line-protection device, not a multifunction power monitor. ## Thermal derating and ambient limits Above that, derating begins: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. ## Coordination and selectivity note For selectivity studies, the TM240 release is a fixed thermal-magnetic design — no electronic adjustment. The 100% N-conductor protection rating means the neutral pole is fully rated, not derated. The latching endurance is 15,000 operations, adequate for distribution duty but not for frequent switching.","metaTitle":"Siemens 3VA1220-4GF42-0HC0 SENTRON MCCB, 200 A, 4-Pole, Line","metaDescription":"Siemens 3VA1220-4GF42-0HC0 SENTRON molded case circuit breaker, 200 A rated continuous current, 4 poles, 70 mm depth. 121 kA at 240 V, 75.6 kA at 415 V.
