Rated operating voltage spans 20 to 690 V. That tells you where the arc extinction is comfortable and where you need upstream current-limiting fuses.
Any mounting position is allowed. Minimum clearances to adjacent metal parts: 50 mm upwards and downwards, 30 mm at the sides, zero forwards and backwards. That zero-clearance rear face means it can sit flush against a backplate — useful when packing a panel tight.
Ratings & Coordination
For transformer primary protection, the fuse coordination values are given: at 400 V, a gL/gG fuse up to 63 A; at 500 V and 690 V, up to 50 A. Motor horsepower equivalents are listed for reference: 15 hp at 460/480 V, 7.5 hp at 220/230 V, 5 hp at 200/208 V, 3 hp at 230 V, 2 hp at 110/120 V. Maximum switching frequency in AC-3 duty is 15 operations per hour.
Terminals & Wiring
Main current circuit connections use spring-loaded terminals. Accepts solid or stranded copper: 2 x 1 to 10 mm² per terminal. Strip length and torque values follow the standard SIRIUS spring-clamp spec — no special tooling needed beyond a screwdriver.
Environmental
That's a standard industrial envelope — no special climate control required for warehousing.
