Trip Class 10 means it will trip within 10 seconds at 7.2× the thermal setting, protecting the motor during a locked-rotor start without nuisance tripping on normal acceleration. This is a self-contained motor starter in an IP55 enclosure — sized for washdown or dusty environments on the plant floor, not a DIN-rail module for a clean control cabinet. Dimensions are 145 mm deep, 182 mm wide, 220 mm tall. Mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward, so it can be oriented to fit tight spaces or cable entries. The supply voltage is 340-440 V AC, 50/60 Hz. It has one digital input and uses electromechanical switching contacts with bimetal motor protection. Short-circuit protection is handled by upstream circuit-breakers — no separate fuse block needed.","metaTitle":"Siemens 3RK4353-3NR58-0BA0 SIRIUS Motor Starter, 10 A AC-3","metaDescription":"Siemens SIRIUS 3RK4353-3NR58-0BA0 direct-on-line motor starter, 10 A AC-3 at 400 V, Trip Class 10, IP55.
