The CLASS 10 trip curve means it will disconnect within 10 seconds under locked-rotor conditions, which protects the motor winding without nuisance tripping on normal start-up inrush. It's a self-contained unit: one digital input for control, electromechanical switching contacts, and built-in short-circuit protection via circuit-breakers. The bimetal motor protection element handles the thermal overload sensing. ## Panel fit and mounting flexibility The enclosure measures 182 mm wide, 220 mm high, and 145 mm deep. That depth is the distance from the mounting surface to the front of the housing — critical when you're fitting it into a shallow back panel or a gland-plate clearance zone. IP55 protection means the unit is dust-protected and can handle water jets from any direction — suitable for washdown areas or outdoor enclosures where condensation is a concern.","metaTitle":"Siemens 3RK4353-3CR58-0BA0 Motor Starter, CLASS 10, 1 A AC-3","metaDescription":"Siemens SIRIUS 3RK4353-3CR58-0BA0 direct motor starter, CLASS 10 trip, 1 A at 400 V AC-3, IP55.
