Electromagnetic relay PK-4PR 48V 48V AC/DC contact: 2P I=2x8A 2R I=2x8A 1 module PK-4PR-48V

Electromagnetic relay – reliable circuit switching

The PK-4PR relay is a solid and compact device designed for reliable switching of electrical circuits. It is ideal for both home installations and more demanding industrial applications. The single-module design simplifies mounting on a standard TH-35 rail, saving space in the distribution board. This relay is particularly useful where remote load control or protection of sensitive circuits from high voltages and currents is required.

Functionality and application

The PK-4PR relay is versatile thanks to the possibility of powering it with both AC and DC voltage of 48V. It has two changeover contacts (NO/NC) and two normally open contacts (NO), allowing for the implementation of various control functions. The rated current of the contacts is 8A, which allows for the operation of most standard loads. The device finds application in building automation, alarm systems, lighting control and many other applications requiring reliable circuit switching.

Construction and characteristic features

The single-module housing made of high-quality materials ensures durability and resistance to mechanical damage. Screw terminals guarantee a secure connection of wires with a cross-section of up to 2.5 mm². The IP20 degree of protection protects against accidental contact and the ingress of solid objects larger than 12.5 mm. The relay is designed to operate at temperatures from -25°C to +50°C, ensuring its reliability in various environmental conditions. An important aspect is also the lack of forced contact guidance – which translates into a longer device life with proper load selection. It is important to consider the nature of the load (inductive, capacitive) when selecting the relay to avoid shortening its life.
