Applications

The 3RV2011-0CA10 is suitable for protecting small three-phase motors and electrical loads in precision industrial automation applications where reliable overload and short-circuit protection is required for very low motor currents between 0.18-0.25 A. It provides inverse time-delayed protection against overload conditions and instantaneous protection against short-circuits, making it ideal for small motor drives, precision machinery, laboratory equipment, instrumentation systems, and SIRIUS modular system integration requiring size S00 protection for low-power applications.

Operation

When an overload occurs, the motor current rises above the set rated current, heating the integrated bimetal element and causing the device to trip through thermal-magnetic operation. For short-circuit conditions, the electromagnetic release provides instantaneous protection at 3.3 A. The rotary operating mechanism allows manual on/off operation with clear position indication and trip status display. The built-in test function enables verification of overload release operation without electrical load. After tripping, the device must be manually reset by moving the rotary switch to OFF position before reclosing.
