Rated IP54, so it tolerates dust and splash in cabinet-free or light-washdown areas, but not hose-down or submersion. Operating ambient is -25 to +50 °C, which covers most indoor industrial environments without derating. RoHS compliance date is 05/01/2012 (substance prohibitance), meaning it meets EU RoHS and REACH requirements for current installations.","metaTitle":"Siemens 3RK4320-3NQ51-0BA2 SIRIUS Motor Starter","metaDescription":"Siemens 3RK4320-3NQ51-0BA2 SIRIUS motor starter, direct starter, 10 A at 400 V AC-3, AS-Interface bus, IP54, current production.
