The (also recognized as the COCIS GMR-32B phase sequence relay) is a specialized three-phase power supply protection device engineered to defend industrial motors, pumps, escalators, and HVAC compressors from catastrophic electrical faults. Operating primarily across standard industrial environments—ranging up to 380VAC/460VAC at 50/60Hz—this micro-controlled electronic device monitors voltage stability and phase balance in real-time. Utilizing a standard 35 mm DIN rail profile, it offers plug-and-play fault detection that stops equipment startup or triggers controlled shutdowns when volatile grid errors occur.

The GMR-32B is a designed to protect industrial equipment like motors, compressors, and pumps from electrical faults. It monitors the power supply in real-time to detect issues such as phase reversal, phase loss, and voltage imbalances. Core Specifications The (also recognized as the COCIS GMR-32B phase
GMR-32B Phase Controller (or Phase Sequence Relay) is an industrial protective device designed to monitor three-phase power supplies and safeguard equipment like motors and air compressors from electrical faults. Key Features & Functions Comprehensive Fault Detection : Monitors and protects against: Phase Loss : Detects if any of the three phases (R, S, T) are missing. Phase Reversal/Sequence
When installing, choose a location with adequate ventilation and ensure it is not placed directly above heat-generating components like large power contactors or transformers. The control loop gains may be mismatched
