The operating temperature range is -25 °C to 70 °C, with full 200 A current-carrying capacity up to 50 °C; above that, derate linearly to 176 A at 70 °C. Max power loss at rated load is 42 W — relevant for thermal management in a tightly packed enclosure. The 140 mm width across 4 poles means each pole occupies 35 mm — standard for SENTRON 3VA1 frame sizes. Verify the DIN-rail or mounting-plate pitch against the existing cutout; the 158 mm height fits most 200 A MCCB compartments, but check gland-plate clearance for the 70 mm depth plus wiring bend radius. The supplied basic switch is order code 3VA12204GF420AA0 — that is the internal switching mechanism. The shunt trip (STL) release allows a remote control system or emergency-stop circuit to trip the breaker electrically; there is no undervoltage release on this variant, so a loss of control power will not automatically open the breaker. If you are replacing a failed unit or filling a BOM line, this is the active Siemens part number — no second-source cross-reference needed.","metaTitle":"Siemens 3VA1220-4GF42-0HA0 SENTRON MCCB, 200 A, 4-Pole, 121","metaDescription":"Siemens SENTRON 3VA1220-4GF42-0HA0 molded case circuit breaker, 200 A fixed, 4-pole, TM240 release, shunt trip.
