It is configured for starter protection with a TM120M thermal-magnetic release, but note: this variant omits the overload protection element — it provides short-circuit protection only, with an adjustable instantaneous trip Ii = 6–14 × In. The breaker ships with a shunt trip (STL) rated 12–30 V DC or 24 V AC 50/60 Hz, two auxiliary switches (HQ), and one trip alarm switch (HQ). A nut keeper kit is included for secure panel mounting. For selectivity studies, the instantaneous trip range of 6–14 × In (1200–2800 A) lets you coordinate with downstream devices. Because overload protection is absent, this breaker is intended for applications where a separate overload relay (e.g., a motor starter) handles thermal protection; the breaker itself only clears short circuits.","metaTitle":"Siemens 3VA1220-5MH32-0HH0 Circuit Breaker, 55kA @ 415V, 200","metaDescription":"Siemens 3VA1220-5MH32-0HH0 IEC frame 250 circuit breaker, 55kA breaking capacity @ 415V, 200A, with shunt trip and aux switches.
