Description
The Littelfuse 35040026 Adjustable Voltage Monitoring Relay is a durable part that is suitable for three-phase systems with voltage of 380-480V. It constantly checks the voltage levels to prevent the HVAC equipment from being exposed to hazardous conditions such as low voltage and phase loss, which are detrimental to the proper functioning of motors and compressors. It has a DPDT relay for 10A and 15A loads, which does not require a control transformer for its connection, making it easy to install. Some of the advantages are variable restart delay to protect the motor from low voltage during start, LED diagnostic for easy fault finding, and safety from high voltage tripping.
