## Summary description

Relpol MR-GU3M2P is a two-pole sequence and phase-loss monitoring relay rated for 5 A and designed for AC supply voltages 342–457 V. It detects incorrect phase sequence and phase failure to protect three-phase motors and equipment, providing reliable trip/contact switching. Suitable for industrial control panels, motor protection and automation systems.

## Long description

Relpol MR-GU3M2P is a two-pole sequence and phase-loss monitoring relay designed for three-phase AC systems with supply voltage in the 342–457 V range. The device monitors phase sequence and detects phase failure, producing a switching response to protect motors and three-phase equipment from damage caused by incorrect rotation or missing phases. Constructed for panel mounting, the relay provides reliable contact operation rated up to 5 A for control and protection circuits in industrial and automation environments.
Advantages
The MR-GU3M2P offers compact two-pole monitoring with a clear detection of phase loss and incorrect phase sequence without affecting main power circuits. Its operating voltage range covers higher-voltage three-phase installations, and the relay's 5 A contact rating suits control and auxiliary circuits. The device is suitable for integration into control panels and motor protection systems where accurate phase monitoring and dependable switching are required.
Suitable for
Protection of three-phase motors against reversed rotation
Detection of single-phase conditions and phase loss in industrial installations
Integration into motor starter panels and automation control cabinets
Control circuits and auxiliary switching where 5 A contact rating is sufficient
Key specifications
Function: phase sequence monitoring and phase-loss detection
Poles: 2 contact poles
Rated switching current: 5 A
Supply voltage range (AC): 342–457 V
Intended for three-phase AC systems
Mounting: panel / control cabinet integration
How to use
Install the MR-GU3M2P in a suitable control cabinet or panel according to the manufacturer's mounting and wiring guidelines, ensuring correct connection of the three-phase supply to the relay input terminals. Configure any available settings for response behavior if the unit provides adjustable parameters, then connect the relay's output contacts to the motor starter or control circuit that must be interrupted on phase fault or incorrect sequence. Verify wiring and perform functional tests under controlled conditions before placing the protected equipment into normal operation.
Usage recommendations
Use the relay on systems where the supply voltage consistently falls within the specified 342–457 V range and ensure contact loads do not exceed the 5 A rating. Combine the relay with appropriate overload and short-circuit protection devices, and follow applicable electrical standards for installation, earthing, and commissioning to maintain safe and reliable operation.
