It's rated 4 kW at 400 V and 5 hp at 460/480 V, with a Class 10 trip curve that clears overloads fast enough for standard induction motors driving pumps, conveyors, and fans.
The 4 kW at 400 V and 5 hp at 460/480 V tell you the maximum motor size this starter can handle in those voltage bands. The Class 10 overload curve gives you 10 seconds of trip delay at 600% of the set current — fast enough to protect a motor during a stall without nuisance tripping on a normal start. Supply is 24 V DC (20.4 to 28.8 V range) for the control coil and electronics, which is the standard for most PLC-driven panels. The AS-Interface protocol on the M12 addressing plug means this starter talks directly to an AS-i master without a separate I/O block — a wiring saver on distributed machine layouts.
Screw fixing is the specified fastening method. The unit can be mounted vertical, horizontal, or flat — the recommended orientation is horizontal for best heat dissipation. Dimensions are 159 mm deep, 294 mm wide, 215 mm high. The IP65 enclosure lets it sit on the machine frame in a dusty or wet area; the operating temperature range is -25 to +55 °C, and it can be stored or transported from -40 to +70 °C. Shock resistance is rated at 12g for 11 ms, vibration at 7 mm / 2g — tough enough for most industrial floor environments.
