Its 187 kA breaking capacity at 240 V and 121 kA at 415 V tell you it can safely interrupt very high fault currents on the secondary side of a distribution transformer or in a high-capacity industrial panel — not every MCCB at this frame size carries that level of interruption. At 440 V it still holds 30 kA, and at 690 V it manages 17 kA. The breaker carries its full 200 A from 40 °C through 50 °C ambient. At 55 °C it derates to 192 A, at 60 °C to 188 A, at 65 °C to 184 A, and at 70 °C to 180 A. ## Mounting and footprint Dimensions are 158 mm high, 105 mm wide, 70 mm deep. ## What to verify before you buy The breaker does not include a trip indicator, voltage trigger, phase failure detection, ground fault monitoring, or communication function. If your application requires any of those, this is not the variant. The operating temperature range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. Latching endurance is rated at 15 000 operations.","metaTitle":"Siemens 3VA1220-5MH32-0CC0 SENTRON MCCB, 200A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA1220-5MH32-0CC0 molded case circuit breaker, 200A rated, 187kA at 240V, 3-pole, starter protection version.
