Electromagnetic relay PK-4PZ 110V 110V AC/DC contact: 2P I=2x8A 2Z I=2x8A 1 module PK-4PZ-110V

Electromagnetic relay – reliable switching of circuits

The PK-4PZ electromagnetic relay is a component that can be used in both home and industrial installations. The device is designed for direct mounting on a TH-35 rail and is characterized by a compact design – it occupies only one module. This makes it suitable even in tight distribution boards. This relay is universal, as it can be powered by both AC and DC voltage of 110V.

Construction and operating parameters

The PK-4PZ relay has two changeover contacts (NO/NC) and two normally open contacts (NO), providing great flexibility in configuring control circuits. Each of these contacts can handle a current of up to 8A, allowing control of various loads. Electrical connections are made using screw terminals, ensuring a secure and durable connection of the wires. The IP20 protection class guarantees basic protection against touch and dust.

The relay is designed for long-term and trouble-free operation. Its construction provides high resistance to environmental conditions, and the mechanical durability is at least 5 million switching cycles. An important aspect is also the universal supply voltage – 110V AC/DC – which allows you to adapt the device to different control systems. It should be remembered that with inductive or capacitive loads, such as motors or switch-mode power supplies, the contact life may be reduced due to inrush currents during switching. Therefore, the selection of the relay should take into account the nature of the load.

Applications and benefits

The PK-4PZ relay is widely used in building automation, lighting and heating control systems, and in industry for controlling various electrical devices. Its compact dimensions make it easy to install in tight spaces, and the universal supply voltage increases installation flexibility. Thanks to two changeover contacts and two normally open contacts, it is possible to implement complex control functions without the need for additional elements. Solid construction and high durability translate into reliable operation for a long time.
