No undervoltage release is fitted, and no communication module is integrated; this is a standalone line-protection device, not a power-monitoring breaker. Height is 158 mm — confirm the mounting footprint against your existing panel layout, especially if replacing a different frame size. ## Thermal derating and trip coordination The TM240 release has an adjustable Ir up to 200 A. For frequent switching duty (motor starting, capacitor bank), consider a contactor ahead of this breaker; the MCCB is designed for infrequent isolation and fault protection, not repetitive load switching.","metaTitle":"Siemens 3VA1220-6EF32-0KF0 SENTRON MCCB, 200 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1220-6EF32-0KF0 molded case circuit breaker, 200 A rated continuous current, 220 kA breaking capacity at 240 V.
