Gmr32b Phase Controller Manual ((free)) Info
The GMR32B is a simple device to wire. It has clear, numbered terminal blocks for power input and relay output.
What specific (e.g., heating element, motor, transformer) are you connecting to the controller?
: Series-wire these into your master control contactor coil line. When the incoming utility power is healthy, the GMR-32B closes these contacts, allowing the machine to start. gmr32b phase controller manual
The GMR-32B functions independently of the circuit's load current, focusing strictly on sampling voltage behaviors across the incoming line. Specification 380VAC to 460VAC, 50/60Hz Monitored Circuit Types Industrial Three-Phase (220V, 380V, 440V, 460V) Power Consumption ≤is less than or equal to Contact Form Configurations Two normally open (NO), two normally closed (NC) Conventional Heating Current Connection Capacity 250VAC @ 6A (Resistive) / 30VDC @ 3A Ambient Temperature Range -10°C to +55°C (Up to 60°C for Smart Series variants) Mounting Architecture

Typically 380V AC (supports industrial levels like 220V, 440V, and 460V at 50/60Hz).
Adjust upstream voltage regulation settings or verify wire gauge sizes can handle peak inductive loads. Preventative Maintenance & Safety Guidelines : Series-wire these into your master control contactor
The (also recognized as the GMR-32B Phase Sequence Relay) is a critical industrial safety component designed by brands like Cocis (SICCOS) and Dewin to protect three-phase motor systems and electrical infrastructure. Operating primarily within industrial environments, this device prevents catastrophic motor failures caused by power supply abnormalities.
Power distribution across all three phases is properly balanced, and the phase rotation is correct. The relay contact remains energized to close your main control loop.
Debris inside the enclosure or welded internal contact points due to short-circuit overcurrent conditions beyond the 8A relay rating.
