The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, making it suitable for high-fault-current industrial distribution panels where selectivity and SCCR headroom are required. ## Interrupting capacity and thermal performance The continuous current holds flat at 200 A from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C — no surprise if the panel runs warm. Power loss is 42 W maximum at rated load, which factors into enclosure ventilation calculations. ## Panel integration and dimensions The 4-pole width (140 mm) matches the standard 4-pole SENTRON 3VA frame — no oddball spacing. The TM240 release is factory-set; no undervoltage release or ground-fault module is included (specified as \"without\" on both).","metaTitle":"Siemens 3VA1220-5EF42-0AB0 SENTRON MCCB, 4P, 200A, TM240, 18","metaDescription":"Siemens 3VA1220-5EF42-0AB0 SENTRON molded case circuit breaker, 4-pole, 200A at 40°C, TM240 release, 187kA at 240V.
