Product details

It's built for washdown environments with an IP65 rating, so it can sit right on the machine frame without a separate control cabinet.

At 500 V it's also rated 5.5 kW, and at 575/600 V it handles up to 10 hp — so it covers common North American and European voltage bands without derating surprises. The trip class is field-selectable among CLASS 5, 10, 15, and 20, which means you match the thermal overload curve to the motor's startup time: fast for low-inertia fans, slower for high-inertia loads like centrifuges. It communicates over AS-Interface (the flat two-wire fieldbus), so if your line already uses AS-i for sensors and actuators, this starter integrates without a gateway. The four digital inputs onboard handle local start/stop or feedback, and addressing is done through an M12 plug — no DIP switches to mis-set. The IP65 enclosure means the unit survives high-pressure washdown — food, beverage, or chemical processing lines where you hose down the equipment daily.

Frequently asked questions

What are its key ratings for motor control?

It's rated 5.5 kW at 400 V and 500 V, 7.5 hp at 460/480 V, and 10 hp at 575/600 V. The trip class is selectable between CLASS 5, 10, 15, and 20.

Can this starter be used in washdown environments?

Yes, the IP65 rating means it's protected against dust ingress and low-pressure water jets from any direction. Suitable for food, beverage, or chemical processing areas where equipment is hosed down.

What fieldbus does it support?

It communicates via AS-Interface (AS-i). It does not support PROFIBUS DP or PROFINET natively.
