That 200 A holds flat through 50 °C — no derating needed in a warm enclosure — then steps down to 194 A at 55 °C and 176 A at 70 °C, so the real-world trip point shifts with ambient. The interrupting ratings climb steeply with voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. The TM240 release is a fixed thermal-magnetic type — no interchangeable trip unit, no electronic adjustment — which keeps the bill of materials simple for a line-protection role where the trip curve is known at design time. Two HP auxiliary switches are built in, giving status feedback for PLC inputs or remote indication without an add-on module. ## Integration into the panel Power loss is 42 W maximum at rated current, so the enclosure needs enough ventilation or forced cooling if multiple breakers are ganged in a sealed cabinet — 42 W per pole times three poles is 126 W total thermal load to manage.","metaTitle":"Siemens SENTRON 3VA1220-5EF32-0AB0 MCCB, 200 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1220-5EF32-0AB0 molded case circuit breaker, 200 A continuous, 3-pole, TM240 release, 187 kA interrupting at 240 V.
