Introduction

K81AB47 is a power relay with a operating current of over 2 amps. It enables users to switch high-current circuits without having to manually operate the relay. This power relay has a variety of applications, from providing emergency interruption of electricity supply during emergencies to providing electrical isolation and/or protection during operation of high-current equipment. This article discusses the application field and working principle of K81AB47 power relay.

Application Field

K81AB47 power relay has multiple applications that are related to its ability to switch high current circuits. Its can be used to turn on and off machines such as motors, pumps, compressors, and HVAC systems, as well as to provide emergency interruption of electricity supply in case of an emergency. It can also be used to provide electrical isolation and/or protection during operation of high-current systems. For example, it is often used to ensure reliable and safe operation of x-ray systems or welding equipment.

K81AB47 power relay is also commonly used for power control in industrial applications, such as in electric motor starters, motor control centers, and fused disconnect switches. It is also used as an integral component of automatic electrical power distribution systems, providing protection and isolation to prevent hazards. In addition, it can be used for remote control of high-current circuits, such as those used in lighting systems, security systems, or elevators.

Working Principle

K81AB47 power relay works by creating an electro-magnetic field in order to make or break contact. When the relay is energized, an armature is attracted to a coil, creating an electromagnetic field. This force causes the contacts on the relay to close, completing the circuit and allowing electricity to flow through. When the relay is de-energized, the force of the electromagnetic field is removed and the armature is released, causing the contacts to open and breaking the circuit.

In order to ensure reliable and safe operation of the relay, K81AB47 is equipped with a number of safety features, such as a hermetically sealed environment, an arc-extinguishing chamber, triple-channel contact protection, and failed circuit isolation. This ensures that the relay will not overheat or cause sparks or shorts in the event of contact wear or failure.

K81AB47 power relay is a robust and reliable power relay that can be used for a variety of high current applications. Its ability to switch high-current circuits, as well as its safety features, make it an excellent choice for a wide range of applications.
