The rated insulation voltage spans 20 to 690 V, so it's suitable for 400 V and 480 V panels as well as 690 V installations.
Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm at the side, zero forwards and backwards. That means it can sit tight against the back panel and the cabinet door, but needs headroom and footroom for wiring and arc deflection. Main contact terminals are M3 screws, accepting 2×(0.75 to 2.5 mm²) solid or stranded, or 2×4 mm².
