Electromagnetic relay PK-3P 24V AC/DC, contact: 3P I=3x8A, 1 module PK-3P-24V

Electromagnetic relay – reliability and compact dimensions

The PK-3P electromagnetic relay is a solid solution for controlling electrical circuits, designed for both professional and home use. Its construction based on electromagnetic technology ensures reliable switching of the load, and its compact size – easy mounting in tight spaces. This relay is particularly useful in applications requiring frequent switching of the load, such as controlling lighting, heating or electrical appliances.

Construction and application

The PK-3P relay is characterized by three switchable contacts (3P), which allows for controlling various types of loads. The rated current of 8A per contact allows for servicing most standard receivers. Mounting on a 35mm rail is a standard in electrical installations, which facilitates the integration of the relay with the existing infrastructure. 24V AC/DC power supply ensures wide compatibility with various voltage sources. The single-module housing minimizes the space occupied in the switchgear cabinet.

The relay finds application in:

• Home automation – controlling lighting, blinds, garage doors.
• Heating systems – switching on and off electric heaters, circulating pumps.
• Industrial installations – controlling motors, solenoid valves.
• Lighting – controlling various types of light sources (bulbs, halogen lamps, fluorescent lamps).
• Alarm and fire systems – as an element switching alarm signals.

Key features and benefits

• Universal power supply: The ability to power with both AC and DC voltage (24V) increases installation flexibility.
• High reliability: Construction based on proven solutions ensures long-term and trouble-free operation.
• Compact dimensions: Single-module housing allows for saving space in the switchgear cabinet.
• Easy mounting: Standard mounting on a 35mm rail facilitates integration with the existing infrastructure.
• Three switchable contacts: Allow you to control different types of loads with a single relay.
• Overload protection: Rated current of 8A ensures safe operation with most standard receivers.
• Protection class IP20: Provides basic protection against touch and dust.
• Mechanical strength: Designed to operate in harsh environmental conditions (operating temperature -25 ÷ 50 °C).

The height of the relay is 90 mm, and the depth is 65 mm. The rated control voltage for AC and DC is 24 V. The relay has three switchable contacts with a rated current of 8 A each and a protection class of IP20.

It is important to select appropriate wires and protections for a given load to ensure safe and reliable operation of the entire system. When connecting inductive or capacitive loads, their impact on the durability of the relay contacts should be taken into account – excessive inrush currents may shorten the life of the device.
