Double Delay Time Relay

Double Delay Time Relay GRT8-2T

GEYA Double Delay Time Relay is for gradual switching of heavy powers like heating and prevents current strokes in the main. It has protection and monitoring of motors with integrated PTC thermistor temperature sensors. It has a range of phase loss and phase failure monitoring relays.

GEYA Double Delay Time Relay has motor monitoring for heavy starting, high switching frequency, single phase operation, high ambient temperature, and insufficient cooling.It has solid state thyristor output, simple two wire connection, and flame-retardant housing.
