This is a line-protection variant, meaning the TM240 release is set for cable and busbar protection rather than motor or generator duty. No undervoltage release, no auxiliary contacts, no ground-fault monitoring are fitted on this order code, so any of those functions would need an external module or a different variant. Above that, the TM240 release begins to thermally track: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. ## Front protection and mechanical endurance No trip indicator is fitted, so fault events must be identified by the breaker position or a separate indication circuit.","metaTitle":"Siemens 3VA1220-6EF42-0HA0 SENTRON MCCB, 200 A, 4-Pole, 220","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0HA0 molded case circuit breaker, 200 A rated, 4-pole, 220 kA at 240 V.
