Three poles, front-terminal busbar connection, and a 70 × 76.2 × 130 mm footprint that matches the 3VA1 molded-case breaker family, so it drops into the same panel cutout and busbar layout as a standard 3VA1 MCCB of the same frame.
Rated insulation voltage 800 V, max operational voltage 690 V AC 50/60 Hz and 500 V DC — covers standard 400/480 VAC industrial panels and 500 VDC battery or solar strings. IP40 on the front — suitable for general indoor panel use where no water jets or hose-down cleaning is expected. The auxiliary contact package (1 auxiliary switch HQ + 1 trip alarm switch HQ, 2 CO contacts total) gives you a status feedback pair for the PLC or indicator lamp: one NO/NC for the open/closed position, one for the trip/alarm state. Mechanical endurance rated at 15 000 operating cycles — typical for a switch disconnector in this class; fine for daily or weekly switching in a maintenance disconnect role, not intended for high-frequency motor starting.
Same 70 mm depth, 76.2 mm width, 130 mm height as the 3VA1 MCCB line — mounts on the same DIN rail or panel-mount adapter, connects via the same front-terminal busbar system. If you are swapping a 3VA1 breaker for this disconnect in an existing panel, the busbar drilling and terminal layout are identical; no rework on the copper. The busbar connection (nut keeper kit included per the description) saves time versus lug terminals on multi-pole runs.
