Priority relay PR-602 contacts: 1NO, Imax=16A, surface mounting

Priority relay – reliable load management

The PR-602 priority relay is a device designed to protect the electrical installation from overload, especially in situations where there are high-power receivers in the circuit. Its main task is to ensure priority power supply for one of the receivers, temporarily disconnecting the lower-priority circuit in the event of exceeding the set current draw threshold. This is an ideal solution for installations where simultaneous switching on of all receivers could cause the protection to activate.

Functionality and application

The PR-602 relay finds application wherever it is necessary to divide the load into priority and non-priority. It can be used in homes, workshops, industrial facilities or in electric heating systems. Thanks to the adjustable trigger current (in the range of 2-15A), it can be adapted to the specific needs of the installation. A 1Z (normally open) contact ensures reliable circuit switching. Surface mounting simplifies installation and integration with existing infrastructure.

Characteristics and benefits

• Load prioritization: Ensures continuous power supply for the most important receivers, even in the event of a temporary overload of the installation.
• Adjustable trigger current: Allows precise adjustment to the load characteristics and protection against unwanted circuit disconnection. The adjustment range of 2-15A allows for flexible adaptation to different applications.
• Surface mounting: Facilitates and speeds up installation, minimizing costs and downtime.
• Wide rated voltage range: Operation at 230V AC ensures compatibility with most standard electrical installations.
• High reliability: Solid construction and careful workmanship guarantee long-lasting and trouble-free operation of the device. IP20 protection class provides basic protection against touch and dust.
• Compact dimensions: 50x67x26mm allow for mounting in limited space.
• Rated current 16A: Ensures safe operation for most standard receivers.
• Switching/return delay 0.1 seconds: Minimizes the risk of damage related to frequent switching on and off.

The PR-602 relay is a practical solution for every installer and end user looking for a reliable way to manage electrical load and ensure priority power supply for key devices.
