Connect the raw, unswitched supply lines directly to the input side of the relay. Connect the to terminal 1 . Connect the L2 line to terminal 2 . Connect the L3 line to terminal 3 .
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
designed to monitor electrical phase order and protect motors or appliances from damage due to phase reversal or failure. Unlike standard power controllers that regulate current, this device acts as a "vigilant guardian" that isolates the circuit immediately upon detecting a deviation. AliExpress Core Specifications Rated Voltage: 300–400VAC (typically 380VAC), 50/60Hz. Contact Form:
Issue: System has a known fault, but the relay fails to trip. Total failure of incoming line power, or blown
The (also manufactured under brands like COCIS / SICCOS ) is a high-precision, three-phase power supply protector designed to shield industrial equipment from critical electrical faults. Deployed heavily in heavy-duty machinery, HVAC systems, and elevator control panels , this phase sequence relay acts as an automated defense system. It monitors voltage stability and phase integrity to prevent catastrophic motor failure.

Often associated with power supply protectors and PLC-compatible modules (e.g., GLOFA-GMR series). Aksa Mühendislik Installation & Safety Guidelines Power Off:
The GMR32B phase controller is designed to provide precise control over the phase angle of electrical signals, allowing for efficient regulation of power flow. Its advanced design and robust construction make it suitable for use in a wide range of applications, including industrial automation, power supplies, and motor control systems. Internal Power Consumption: ≤is less than or equal
Before installing or handling the device, implement strict procedures to guarantee the main breaker is entirely de-energized. Touch terminals only when power is verified off to prevent severe electric shock.
A standard phase controller usually follows this logic:
Monitors for overvoltage, undervoltage, phase sequence reversal, and phase failure. Rated Voltage: Typically 380V AC for three-phase systems. Standard DIN rail mounting for industrial control panels. Compatibility:
