Product Description
Siemens 3RV2021-1JA10 Motor Protection Circuit Breaker is purpose-built for safeguarding electric motors in demanding industrial environments. Featuring a current rating of 10A/7A and a maximum supply voltage of 690V, this circuit breaker ensures the safety and reliability of motor-driven systems.
Its magnetic sensing mechanism provides accurate response to overload and short-circuit conditions, acting as a Class 10 tripping device that disconnects the motor within 10 seconds during overcurrent events. The three-pole circuit design offers comprehensive phase protection, making it suitable for multi-phase machinery.
The IP20 rated housing guarantees touch safety against electrical shocks, and screw-type terminals support cable sizes from AWG 16 to 8 (2.5 to 10mm²), facilitating secure and easy connections. Installation is simplified with options for screw or snap-on DIN rail mounting, allowing flexibility in panel layout.
This model from Siemens' 3RV2 series demonstrates robust endurance by withstanding 6kV surge voltage and operational humidity up to 95%. Its temperature tolerance spans from -20°C to 60°C, making it a strong candidate for harsh ambient conditions in factories, workshops, or automation control panels.
Measuring 45mm in length, 96.9mm in width, and 97mm in depth, the compact form factor is ideal for space-constrained industrial cabinets. The circuit breaker conforms to international standards including CCC, ABS, ATEX, CE, VDE, UL, UKCA, RoHS, CSA, LRS and EAC, ensuring reliable performance across global applications.
Common use cases include protection of pumps, conveyor motors, HVAC systems, and manufacturing machinery in industrial, commercial, and laboratory settings. The device contributes to the prevention of equipment damage and reduction of downtime by providing dependable overload and short-circuit protection.
