That matters when you are coordinating with downstream breakers: you need to know the TM240's band, not guess at a dial setting. The 200 A rating holds flat from 40 °C through 50 °C ambient, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If your panel hits 55 °C near the breaker — common in a tightly packed enclosure with a transformer nearby — you lose 6 A of headroom. Plan the continuous load at 80 % of the derated value and you stay inside the thermal curve. It is a straight-ahead line-protection breaker with a remote-trip capability and a separate alarm contact for the maintenance PLC. Footprint: 140 mm wide, 158 mm tall, 70 mm deep.","metaTitle":"Siemens 3VA1220-5GF42-0HH0 SENTRON MCCB, 200 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1220-5GF42-0HH0 molded case circuit breaker, 200 A rated, 4-pole, line protection, 187 kA at 240 V.
