## Summary description

The Zamel PRM-10 is a resistance relay designed for monitoring temperature via a PTC probe. Operating at 230V AC, this device provides reliable protection and control in industrial or building automation systems. It is ideal for detecting overheating in motors, transformers, and other electrical equipment, ensuring safe operation through precise resistance measurement and switching capabilities.

## Long description

The Zamel PRM-10 is a specialized resistance relay engineered for precise temperature monitoring using a PTC probe. Operating on a 230V AC power supply, this device serves as a critical component in industrial and building automation systems, providing reliable protection against overheating for various electrical equipment. By continuously measuring resistance levels, the relay ensures that connected machinery operates within safe thermal limits, triggering protective switching actions when necessary.
Advantages
The primary advantage of the Zamel PRM-10 lies in its high reliability and accuracy in thermal management. Its design allows for seamless integration into existing control panels, offering a robust solution for preventing damage to motors, transformers, and other sensitive electrical components. The device is built to withstand demanding environments, ensuring consistent performance and long-term operational safety without the need for frequent manual intervention.
Suitable for
Monitoring temperature in electric motors
Protecting transformers from overheating
Industrial automation control systems
Building management and HVAC safety circuits
When it may not be suitable
This relay is specifically designed for use with PTC probes and may not be compatible with other types of temperature sensors such as thermocouples or RTDs. It is intended for standard 230V AC electrical systems and should not be used in applications requiring different voltage levels or specialized industrial communication protocols.
Key specifications
Supply voltage: 230V AC
Sensor type: PTC probe
Function: Resistance-based temperature monitoring
Application: Overheating protection and switching
How to use
Installation should be performed by a qualified professional in accordance with local electrical regulations. The PTC probe must be securely mounted to the heat-sensitive part of the equipment being monitored. Connect the probe to the designated input terminals of the PRM-10 and wire the relay output into the control circuit of the motor or transformer starter. Once powered, the device will automatically monitor the resistance of the probe and activate the relay contacts if the temperature exceeds the defined threshold.
What to consider before purchase
Verify that your equipment is equipped with a compatible PTC sensor
Ensure the supply voltage matches the 230V AC requirement
Confirm the physical space available in your control cabinet for DIN-rail mounting
Usage recommendations
Regularly test the relay functionality during scheduled maintenance to ensure the protection circuit remains active and responsive to temperature changes.
