This component, part of the SIRIUS product family, is engineered to provide Class 10 protection, which is essential for safeguarding motors from overload conditions. With a standard breaking capacity, it is suitable for use in systems with operating voltages up to 690V.
The 3RV1011-1KA20 features a compact size S00 frame, making it an ideal choice for space-constrained environments. It is equipped with three poles for the main current circuit and offers a reliable thermomagnetic release mechanism for short-circuit protection. The adjustable pick-up value current of the current-dependent overload release ranges from 9 to 12 A, allowing for precise calibration according to the motor's requirements.
Installation is made simple with screw and snap-on mounting options onto a 35 mm standard mounting rail according to DIN EN 50022, and the device can be installed in any orientation. The circuit breaker's front-side Cage Clamp terminals facilitate quick and secure electrical connections for both the main and auxiliary circuits.
Designed to withstand challenging conditions, the 3RV1011-1KA20 operates reliably within an ambient temperature range of -20 to +60°C and is rated for mechanical service life of 100,000 switching cycles for the main contacts. Its shock resistance and surge voltage resistance ensure durability and consistent performance even in demanding industrial settings.
