Those numbers mean it can safely interrupt very high fault currents at common distribution voltages — useful when this breaker sits close to a large transformer or in a high-capacity switchboard where fault levels exceed what a standard 50 kA or 65 kA MCCB can handle. ## Thermal derating and ambient conditions Above that, it derates linearly: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. If the panel runs hot — say, adjacent to a drive cabinet or in a non-climate-controlled enclosure — size the load side for the derated figure at your actual ambient, not the nameplate 200 A. The storage limit governs shipping and warehouse conditions, not running duty. It also includes an undervoltage release (UVR) — the factory-fitted accessory order code for that release is 3VA9608-0BB25. The UVR will trip the breaker if control voltage drops below its dropout threshold, which is standard for emergency-stop or undervoltage protection schemes. Mechanical endurance is rated at 15,000 operations — typical for a distribution MCCB that sees infrequent switching. The lifecycle stage is listed as current — meaning Siemens still actively manufactures and supports this order code.","metaTitle":"Siemens 3VA1220-5EF32-0DH0 SENTRON MCCB, 200 A, 3-Pole, Line","metaDescription":"Siemens 3VA1220-5EF32-0DH0 SENTRON molded case circuit breaker, 200 A rated, 3-pole, TM240 release, 187 kA at 240 V.
