Priority relay for direct connection 230V 16A FF PR-612

Priority relay FF PR-612 is a compact electromechanical device designed for direct connection to a 230 V single-phase supply and rated for continuous switching of loads up to 16 A. The relay provides a controlled way to prioritize one circuit over another, enabling seamless selection between primary and secondary power sources or selective supply of critical loads. It is intended for fixed installation in electrical distribution systems where a designated source must take precedence.

Advantages

The device combines a simple wiring scheme with reliable switching performance and a slim enclosure suitable for mounting in distribution panels. Its rated 230 V operation and 16 A load capacity match common residential and light commercial circuits. The relay design reduces manual intervention by automatically applying the selected priority logic, helping to protect sensitive equipment by ensuring that the preferred supply is connected when available.

Suitable for

• Automatic selection between primary and backup power sources
• Priority feeding of critical circuits such as heating, refrigeration, or communication equipment
• Load shedding schemes where non‑essential loads are disconnected to preserve power for priority circuits
• Small commercial and residential distribution panels requiring prioritized supply management

Key specifications

• Supply voltage: 230 V AC
• Rated switching current: 16 A
• Mounting: panel or DIN-rail compatible enclosure (compact form factor)
• Operating principle: priority relay for direct connection between two circuits
• Typical applications: source selection, load prioritization, backup feed control

How to use

Install the relay in the distribution enclosure close to the circuits it will control, following local electrical codes. Connect the supply and load conductors to the appropriate input and output terminals as indicated in the manufacturer wiring diagram. Ensure that the connected loads do not exceed the 16 A rating and that the supply is 230 V AC. After wiring, verify correct operation by switching sources to confirm the relay routes power according to the configured priority.

Usage recommendations

Use this relay in installations with properly sized conductors and protection devices (circuit breakers or fuses). For critical applications, combine the relay with monitoring or alarm systems and ensure periodic inspection to confirm contact integrity and proper function.
