Siemens' 3RV1021-0KA10 is a motor protection circuit breaker from the SIRIUS series known for its reliability in a multitude of electrical applications. It operates at a voltage rating of up to 690 V and weighs just 0.8 lbs, ensuring both lightness and durability for easy integration into various systems.

The overload current can be adjusted within a range of 0.9 to 1.25 A, allowing for tailored settings to optimize motor protection. When engaging in short-circuit situations, the breaker releases at 16 A to secure equipment and prevent damage. With three poles, this model is well-equipped for three-phase applications and follows a trip class of 10.

Designed to operate across a broad temperature spectrum, it can function between -20°C and 70°C. Likewise, it can be stored in conditions ranging from -50°C to 80°C. This versatility permits use in diverse climates and environments. Additionally, the device can be installed at altitudes as high as 2000 meters, expanding its applicable range.

The IP20 rating on the front indicates its degree of protection against moisture and solid objects, assuring safe usage in appropriate environments. Furthermore, with a remarkable breaking capacity (Icu) of 100 kA at voltages of 400V, 500V, and 690V, and an impulse voltage resistance of 6000 V, it is ready to handle various operational demands effectively. Overall, the 3RV1021-0KA10 serves as an essential component in safeguarding motor systems against overloads and short circuits.
