The Siemens 3VA2220-0MN32-0AA0 is a 3-pole SENTRON molded case circuit breaker rated for 200 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. That makes it a straight drop-in for a 200 A bus or feeder that sees warm enclosure temps without recalculating the wire size. It's built around the ETU350M electronic trip unit with adjustable trip classes 10A, 10E, and 20E, so it's specced for motor protection duty — the 10A class catches standard motor starts, and the 20E gives headroom for high-inertia loads like fans or centrifuges. Phase failure detection is onboard, which keeps a single-phased motor from cooking before the overload curve catches it. The 86 mm depth, 105 mm width, and 181 mm height fit the standard SENTRON 3VA footprint — same panel cutout as other 3VA breakers in this frame size.
Sourcing and lifecycle — still a current catalog line
No undervoltage release or shunt trip fitted from the factory — if you need UVR for a safety circuit or remote trip, that's an accessory add-on. No communication function onboard either; this is a standalone thermal-magnetic replacement with electronic trip, not a networked breaker.
