Description
The Littelfuse 202-RP Reverse-Phase Relay is a complex voltage control equipment used in three-phase systems with a voltage of 190-480V AC and frequency of 50/60 Hz. It also constantly checks phase reversal and shuts down when the reverse-phase condition exists to protect essential HVAC equipment like fan motors, scroll compressors, grinders, conveyors, elevators, and escalators. This relay can automatically determine the correct current setting, has adjustable time delays, and has LED lights to easily diagnose faults. It means that it protects the motor from phase reversal and increases the system since it will switch off and resume operation once normalcy is restored.
