Priority relay PR-615 with bypass channel, setting 4-30A, contacts: 1NO, Imax=16A, 1 module

Priority relay – intelligent load management

The PR-615 priority relay is a reliable device designed to protect electrical installations from overload, especially in situations where there are high-power receivers in the circuit. Its through-channel design simplifies installation and provides galvanic isolation of the measurement circuit. This is an ideal solution for both professional installers and end-users looking for a safe and effective way to manage energy.

Application and functionality

The PR-615 relay is used wherever there is a risk of overloading the installation as a result of the simultaneous operation of several high-power receivers. The device automatically disconnects the non-priority circuit after exceeding the set current draw threshold in the priority circuit, ensuring continuous power supply to the most important devices. This protects the installation from damage and downtime. The through-channel for the current-carrying wire of the receiver (with a diameter of up to 4 mm) facilitates integration with the existing electrical infrastructure.

Construction features and mounting

The relay is designed for mounting on a standard 35 mm DIN rail, which ensures quick and easy installation in electrical distribution boards. Compact dimensions (1 module – 18 mm wide) allow for efficient use of space in control cabinets. The device is characterized by high quality of workmanship and durability, which guarantees reliable operation for a long time. Adjustment of the tripping threshold in the range of 4-30A allows for precise adaptation to the specific needs of the installation. The relay has 1Z (NO/NC) contacts, which provides flexibility in configuring control circuits. The IP20 protection class provides protection against touch and dust.

Benefits for the installer and end-user
