The Siemens SENTRON 3VA2220-7MN32-0BC0 is a 3-pole molded case circuit breaker (MCCB) in the motor protection variant, rated for 200 A continuous current. It carries a punishing interrupting capacity — 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 5.2 kA at 690 V — so it can sit upstream of a motor branch or a distribution panel where fault currents are high. The 200 A rating holds flat from 40 °C up to 70 °C, meaning no derating headache in a warm enclosure.
Integration dimensions and panel fit
Physical footprint: 105 mm wide, 181 mm tall, 86 mm deep. That 86 mm depth (about 3.4 inches) is shallow enough for most 200 mm deep enclosures, but always check the handle throw and cable bending radius — the breaker itself fits, but the incoming lugs need clearance. The 3-pole block mounts via the standard MCCB footprint; no special adapter plate required.
Electrical environment and compliance
Rated insulation voltage is 800 V, so it's comfortable on 480/600 V systems with margin. Operating temperature spans -25 °C to 70 °C; storage range is -40 °C to 80 °C. The basic switch (the breaker mechanism without accessories) is order code 3VA2220-7MN32-0AA0, which is the core unit this UVR-equipped version builds on.
