The Siemens 3VA2510-6HM42-0JJ0 is a 4-pole IEC frame 1000 circuit breaker with a breaking capacity class H rated at 85 kA at 415 V. It carries the ETU330 LIG trip unit — line protection with adjustable overload (Ir = 400 A to 1000 A), short-circuit (Ii = 1.5 to 10 x In), neutral conductor protection (OFF, 50%, 100%), and ground-fault protection (Ig = 0.2 to 1 x In, tg = 0.1/0.3 s). The shunt trip is wired left-side, 110–127 V AC/DC. Two auxiliary switches and one trip alarm switch are included, all high-performance (HP) contacts.
The 4-pole frame 1000 footprint is common across the 3VA2 family, so panel cutouts and busbar layouts transfer if you swap between variants. The nut keeper kit (included in the order code suffix) secures the breaker against vibration in high-shock installations.
