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.","metaTitle":"Siemens 3RK1325-6LS41-3AA0 SIRIUS Reversing Starter, 5.5 kW","metaDescription":"Siemens SIRIUS 3RK1325-6LS41-3AA0 reversing motor starter, 5.5 kW at 400 V, IP65, AS-Interface, selectable trip class 5-20.
