Priority relay PR-612 contacts: 1NO, Imax=16A, 1 module

Priority relay – reliable installation protection

The PR-612 priority relay is a device designed for use in electrical circuits where at least two high-power receivers are connected. Its task is to provide priority power to one of them, preventing the installation from being overloaded in the event of both receivers being switched on simultaneously. This is an ideal solution for households and commercial facilities where there are devices with high power consumption, such as electric heaters, water heaters or air conditioners.

Functionality and application

The PR-612 relay is mounted on a DIN rail and works with installations with a voltage of 230V AC. Its construction based on a 1Z contact (normally open) ensures reliable circuit switching. The device is used wherever protection against overload caused by the simultaneous switching on of several receivers is necessary. This protects the electrical installation from damage and ensures safe operation. This relay allows you to avoid unwanted tripping of current protection devices, which could disrupt the operation of connected devices.

Key features and benefits

• Priority power supply: Provides a stable power supply for one receiver, even with simultaneous power demand from several devices.
• Overload protection: Protects the electrical installation from damage caused by excessive load.
• DIN rail mounting: Facilitates and speeds up installation in electrical switchboards.
• High reliability: Solid construction and high-quality components guarantee long-lasting and trouble-free operation.
• Fast response: Maximum disconnection time delay of 100ms ensures a quick response in the event of an overload.
• Rated current 16A: Allows you to connect devices with significant power consumption while maintaining installation safety.
• Protection class IP20: Provides protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm – standard protection for devices mounted inside switchboards.

This relay is a simple but effective solution for anyone who wants to protect their electrical installation and ensure trouble-free operation of high-power devices. This is especially important in older installations that may not be adapted to handle modern energy consumers.
