Overload protection is fixed at Ir = 80 A; short-circuit pickup is fixed at Ii = 10 × In (800 A). A shunt trip (STL) rated 12–30 V DC / 24 V AC 50/60 Hz is factory-installed, along with two auxiliary switches (HQ). The 4-pole footprint occupies four module widths in a standard distribution board. The shunt trip coil draws from a separate control circuit (12–30 V DC or 24 V AC); verify the control transformer sizing if multiple breakers trip simultaneously.","metaTitle":"Siemens 3VA1080-3ED42-0HC0 Circuit Breaker, 80A, 25kA @ 415V","metaDescription":"Siemens 3VA1080-3ED42-0HC0 circuit breaker, IEC frame 100, breaking capacity class N, Icu=25kA @ 415V, 4-pole, TM210, In=80A.
