Applications

The 3RV2011-0EA25 is suitable for protecting small three-phase motors and electrical loads in industrial automation applications where reliable overload and short-circuit protection is required for low motor currents between 0.28-0.4 A. It provides inverse time-delayed protection against overload conditions and instantaneous protection against short-circuits, making it ideal for small motor drives, instrumentation systems, automation equipment, precision machinery, conveyor systems, and SIRIUS modular system integration requiring size S00 protection for low-power motor applications with auxiliary switch feedback requirements.

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 5.2 A. The rotary operating mechanism allows manual on/off operation with clear position indication and trip status display. The integrated transverse auxiliary switches provide 1 NO + 1 NC contacts for status feedback and control circuit integration. 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.
