The breaker includes an integrated undervoltage release (UVR), so if control power drops, the MCCB trips — useful for coordinated safety shutdowns on conveyors or kiln drives where loss of control voltage should kill the main power. ## Thermal derating — what 200 A means at 70 °C The 200 A rating holds at 40, 45, and 50 °C ambient. At 55 °C it's 194 A, at 60 °C it's 188 A, at 65 °C it's 182 A, and at 70 °C it's 176 A. ## Panel fit and power loss The design is starter protection, meaning the trip curve is shaped for motor starting duty rather than feeder protection.","metaTitle":"Siemens 3VA1220-6MH32-0DA0 SENTRON MCCB, 200 A, 154 kA at 41","metaDescription":"Siemens SENTRON 3VA1220-6MH32-0DA0 molded case circuit breaker, 200 A rated, 3-pole, starter protection design with undervoltage release.
