Maximum power loss is 44.5 W — useful for estimating heat load in a sealed enclosure. Interrupting capacity tapers 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. For a 480 V panel, the relevant figure is between the 440 V and 500 V ratings — still well above typical available fault current in most commercial and industrial installations. This variant ships with two HQ auxiliary switches and an undervoltage release (UVR) factory-installed. The basic switch assembly is order code 3VA12205EF320AA0, so if you need a replacement internal mechanism, that's the part to reference. It's a clean line-protection MCCB with the aux contacts and UVR already integrated — no field wiring of separate accessories needed.","metaTitle":"Siemens 3VA1220-5EF32-0CC0 SENTRON MCCB, 200 A, 3-Pole, 70 m","metaDescription":"Siemens SENTRON 3VA1220-5EF32-0CC0 molded case circuit breaker, 200 A at 40 °C, 3-pole, 187 kA at 240 V.
