That 125 A figure is the continuous current you size your feeder for — it's not a momentary or fault rating. The interrupting capacity tells the real story for fault coordination: 76 kA at 240 V AC, 53 kA at 415 V AC, 32 kA at 440 V AC, and 11.9 kA at 500 V AC. The TM220 thermal-magnetic release provides LI protection: a thermal element (Ir adjustable 88–125 A) for overloads, and a fixed magnetic instantaneous trip at 10 x In (1250 A) for short circuits. The frame size is 160 A max, so this 125 A unit has headroom on the frame. No auxiliary contacts come fitted (0 CO contacts), and the neutral conductor isn't upgradeable. If you need aux contacts or a shunt trip, you'll add them separately — this is the base line-protection variant. The 3VA1010-2ED32-0JA0 is from the newer 3VA series, which is the direct successor platform to the 3VM1. The 3VA offers a more compact frame and electronic trip units (ETU) with adjustable short-time delay for selective coordination — the 3VM1112-3EE36-0AA2 uses a fixed thermal-magnetic TM220 release. If your panel was specified around the 3VA1010, the 3VM1112 will physically fit the same mounting footprint (both are IEC frame 160, front-connected), but the trip curve and coordination settings are different. The 3VM1 is a simpler, more rugged device; the 3VA gives you finer protection adjustment. For a straight replacement where the original spec was a 3VA, you'd need to verify the coordination study accepts the TM220's fixed instantaneous at 10 x In.","metaTitle":"Siemens 3VM1112-3EE36-0AA2 SENTRON MCCB, 125A, 76kA@240V","metaDescription":"Siemens 3VM1112-3EE36-0AA2 SENTRON molded case circuit breaker, 125A rated, 76 kA at 240 V AC.
