## Summary description

The F&F PR-603 is a priority relay designed to manage electrical loads by automatically disconnecting non-essential circuits when the total power consumption exceeds a set limit. Featuring a 230V operating voltage and 16A current capacity, this device includes a through channel for efficient installation. It is ideal for preventing circuit breaker tripping in residential and commercial electrical systems with high-power appliances.

## Long description

The F&F PR-603 Priority Relay is a specialized electrical control device engineered to manage power distribution by monitoring total consumption. It automatically disconnects non-essential circuits when the load exceeds a pre-defined threshold, effectively preventing circuit breakers from tripping due to overload. Designed for 230V systems with a 16A capacity, this relay features a convenient through channel that simplifies wiring and installation in both residential and commercial electrical panels.
Advantages
This priority relay offers a reliable solution for maintaining electrical stability in environments with multiple high-power appliances. By intelligently managing load shedding, it ensures that critical systems remain powered while secondary circuits are temporarily disabled during peak demand. The integrated through channel design facilitates a clean and efficient installation process, reducing the need for complex external wiring configurations and saving valuable space within the distribution board.
Suitable for
Residential homes with high-power kitchen appliances
Commercial offices managing HVAC and lighting loads
Preventing main circuit breaker overload
Systems where simultaneous appliance operation exceeds supply limits
When it may not be suitable
This device is not intended for use in industrial environments requiring high-frequency switching or loads exceeding the 16A current rating. It is also not suitable for controlling sensitive electronic equipment that requires a constant, uninterrupted power supply without the possibility of temporary disconnection.
Key specifications
Operating voltage: 230V AC
Maximum current capacity: 16A
Function: Priority load shedding
Design: Through channel for simplified installation
How to use
The relay should be installed by a qualified electrician within the main distribution board. Connect the priority circuit and the non-essential circuit according to the provided wiring diagram. Once installed, the device monitors the current flow; when the total load reaches the set limit, the relay automatically cuts power to the non-essential circuit until the demand decreases, at which point it restores power automatically.
What to consider before purchase
Verify that your total electrical supply capacity matches the relay specifications
Ensure the non-essential load does not exceed the 16A limit
Check available space in your distribution board for mounting
Confirm that the priority circuit is correctly identified to avoid accidental disconnection
Usage recommendations
Regularly inspect the electrical connections to ensure they remain tight and free from oxidation. Ensure that the total power consumption of the non-essential circuit does not exceed the relay's rated capacity to prevent premature wear or device failure.
