The Siemens series of 3RV1011 manual motor protectors are used in a wide variety of applications, from pump panels, mass production lines and certain HVAC installations. The bimetallic heating elements in this starter provide over-current protection for both AC and DC motors up to the selected AMP range, in this case up to 0.4 AMPS. The unique feature to this Siemens motor protector is the fourth bimetallic strip, which prevents unnecessary tripping when the temperature of the enclosed panel exceeds the temperature of the motor, saving time and the hassle of restarting the motor. Most important is the phase loss protection as, due to a differential trip bar, trips faster preventing costly damage to the motor that it is protecting when a motor loses its phase.
When combined with an appropriate sized 3RT1 contactor, the 3RV1011-0EA10 forms a combination motor controller for complete motor protection.
