At 690 V it still interrupts 17 kA, covering most 690 V industrial distribution systems. ## Thermal derating and ambient operating range Above that, derating applies: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If the panel internal temperature runs hot — say, near a transformer or in a poorly ventilated enclosure — use the 55 °C or 60 °C column for sizing. The 3-pole width fits standard MCCB panel cutouts or DIN-rail adapter plates.","metaTitle":"Siemens 3VA1220-5EF32-0CA0 SENTRON MCCB, 200 A, 3-Pole, UVR","metaDescription":"Siemens SENTRON 3VA1220-5EF32-0CA0 molded case circuit breaker. 200 A rated at 40 °C, 3-pole, TM240 release, undervoltage release. 187 kA at 240 V.
