Description
The Littelfuse 35040028 Adjustable Voltage Monitoring Relay is a sturdy part used for voltage monitoring in three-phase industrial applications and it is rated for 380V-480V. It constantly monitors the voltage levels of the three phases, the phase failure, phase opposition and other problems that may lead to equipment damage. It is most useful for HVAC systems, motors and generators because it has adjustable trip points and LED lights for testing. Some of the features include a DPDT relay with a current rating of 15A, no need for control transformers and compatibility with 480V controls.
