Gmr-32b Phase — Controller Manual |verified|
is a three-phase sequence monitoring relay (also commonly called a phase controller or protector) used to safeguard industrial equipment like motors, compressors, and pumps from power supply faults. It is widely used in central air conditioning units, elevators, and distribution boxes to prevent damage from phase reversal or voltage imbalances. AliExpress Key Technical Specifications
The most frequent cause of "nuisance tripping." Ensure all terminals are tightened securely.
Follow these steps to mount, wire, and safely power up the GMR-32B for the first time. Step 1: Mechanical Mounting gmr-32b phase controller manual
Many manufacturers offer newer equivalents if the GMR-32B is discontinued. Ask for a cross-reference guide.
: Only one copper wire can be inserted per terminal; dual-wiring for jumping connections requires careful handling. Maintenance Needs is a three-phase sequence monitoring relay (also commonly
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
The GMR-32B must be mounted vertically inside a well-ventilated control cabinet. Mounting Steps Follow these steps to mount, wire, and safely
If the phase sequence (R, S, T) is wired incorrectly during setup, the relay prevents the system from starting. This is vital for equipment like pumps or compressors where running backward causes immediate mechanical destruction. 2. Dynamic and Static Phase Loss Protection
Standard HT35 DIN rail mount or direct mounting via two M4 screw holes. Operating Ambient Temperature: -10°C to +55°C. Relative Humidity: 45% to 85% RH.
