## Summary description

ZAMEL PNM-31 is a three-phase voltage relay designed for monitoring 230/400V AC networks. The device controls voltage presence and protects installations by detecting undervoltage, overvoltage or phase loss conditions across three phases. Intended for electrical panels and automation systems, it helps ensure safe operation of motors, pumps and industrial equipment where phase monitoring is required.

## Long description

ZAMEL PNM-31 is a three-phase voltage relay designed to monitor 230/400V AC electrical networks. The device continuously checks voltage levels across three phases and detects undervoltage, overvoltage and phase loss conditions to protect connected equipment. Built for DIN-rail mounting in electrical panels, the relay is intended for use in automation systems where reliable phase monitoring is required to maintain safe operation of motors, pumps and other industrial loads.
Advantages
The relay provides automatic detection of phase loss and asymmetry, helping to prevent damage caused by single-phasing or unbalanced voltages. Its compact DIN-rail form factor simplifies panel installation and saves space. The unit operates with standard 230/400V AC networks and delivers consistent monitoring without the need for complex external circuitry. Designed for industrial and commercial installations, it supports reliable protection of three-phase equipment and reduces downtime caused by electrical faults.
Suitable for
Protection of three-phase motors and pumps in industrial and commercial installations
Phase presence and symmetry monitoring in automation control panels
Preventive protection for HVAC systems and compressors
Electrical distribution panels in workshops, factories and utility rooms
Key specifications
Supply / monitoring voltage: 230/400V AC three-phase
Monitored conditions: undervoltage, overvoltage, phase loss and phase asymmetry
Mounting: DIN-rail compatible housing for panel installation
Application: continuous three-phase monitoring for motors, pumps and industrial equipment
How to use
Install the relay on a standard DIN rail inside the control panel and connect the three-phase supply to the designated input terminals according to the wiring diagram supplied by the manufacturer. Configure any adjustable thresholds or time delays if the model provides such settings, then feed the relay output to the contactor or control input of the protected equipment. Verify correct operation by applying normal supply and simulating fault conditions to confirm the relay detects phase loss, undervoltage and overvoltage as intended.
Usage recommendations
Ensure all wiring and installation steps are performed by a qualified electrician and comply with local electrical regulations. Keep the relay and panel free from excessive dust and moisture, and perform periodic functional checks to confirm reliable phase monitoring.
