The interrupting ratings tell you where it fits: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. The thermal derating curve is honest: 200 A continuous from 40 °C through 50 °C, then it tapers — 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. The 70 mm depth (2.76 in), 140 mm width (5.51 in), and 158 mm height (6.22 in) fit a standard MCCB footprint on DIN rail or direct-mount plate — measure your enclosure depth before ordering, especially if there's a gland plate or wiring duct behind it. The internal basic switch is order code 3VA12205GF420AA0 — that's the sub-assembly that actually carries the current and trips. The main breaker frame is the enclosure and mechanism; the switch is the replaceable insert. If you ever need to swap the internal switch without pulling the whole breaker, that's the part number to order alongside this one.","metaTitle":"Siemens 3VA1220-5GF42-0AG0 SENTRON MCCB, 200 A, 4-Pole, 70 m","metaDescription":"Siemens 3VA1220-5GF42-0AG0 SENTRON molded case circuit breaker, 200 A, 4-pole, 187 kA at 240 V.
