That thermal curve means you can push it harder in a cool cabinet or must derate in a hot enclosure — the 200 A nameplate is only valid up to 50 °C. Breaking capacity is voltage-dependent: 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. Footprint is 140 mm wide × 158 mm tall × 70 mm deep. That 70 mm depth is shallower than many MCCBs in this current class — useful when mounting in a shallow enclosure or against a rear gland plate. Maximum power loss is 44.5 W at rated current — a factor for thermal management in a sealed enclosure.","metaTitle":"Siemens 3VA1220-5GF42-0CH0 SENTRON MCCB, 200 A, 4-Pole","metaDescription":"Siemens SENTRON 3VA1220-5GF42-0CH0 molded case circuit breaker, 200 A, 4-pole, line protection with undervoltage release.
