Rated 45 kW at 500 V and 21.1 kW at 690 V in AC-3 duty (motor starting/switching under load), it handles the common European 400 V motor range at 37 kW in AC-2. For heavy inrush or reversing duty, AC-4 rating is 66 A at 400 V. Mechanical life is typical 10 million cycles; maximum switching rates range from 300 ops/h in AC-4 to 1000 ops/h in AC-3, so it keeps up with rapid cycling on a conveyor or pump line without derating the coil.
Mounting and wiring in the panel
Footprint is 70 mm wide by 146 mm tall by 152 mm deep. Side-by-side mounting is permitted. Solid wire accepted in two ranges: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Stranded main power wires up to 2x (10 to 50 mm²) — that covers most motor feeds up to the 45 kW rating. Auxiliary/control terminals accept 2x (2.5 to 16 mm²) solid or stranded.
IP20 on the front with cover or box terminal; IP00 at the terminal itself — the terminal area needs finger-safe shrouding in the panel. RoHS compliance date is 05/01/2012, covering the substance prohibitions under EU directive.
