Applications

The 3RV2011-1EA20 is suitable for protecting larger three-phase motors and electrical loads in industrial automation applications where reliable overload and short-circuit protection is required for motor currents between 2.8-4 A with tool-free connection requirements. It provides inverse time-delayed protection against overload conditions and instantaneous protection against short-circuits, making it ideal for motor drives, instrumentation systems, automation equipment, precision machinery, conveyor systems, pump panels, mass production lines, HVAC installations, and SIRIUS modular system integration requiring size S00 protection for motors up to 1.5 kW at 400V with convenient spring terminal connections for easy installation and maintenance.

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 52 A. The rotary operating mechanism allows manual on/off operation with clear position indication and trip status display. The spring-type terminals enable tool-free installation and maintenance, reducing installation time and eliminating the need for tools. The adjustment dial enables precise setting to motor FLA (Full Load Amperage). The built-in test function enables verification of overload release operation without electrical load. The device features phase loss sensitivity for enhanced motor protection and provides over-current protection for both AC and DC motors. After tripping, the device must be manually reset by moving the rotary switch to OFF position before reclosing.
