Power relays, over 2 amps, are generally used for switching and circuit protection applications that require a high-current flow of electricity. The HJ2-L-AC220/240V-R is a type of power relay suitable for these types of applications. In this article, we will discuss the application field and working principle of the HJ2-L-AC220/240V-R power relay.

The HJ2-L-AC220/240V-R is a high-performing single-pole, double-throw power relay with a rated voltage of 240VAC and a static current of 2A. It is designed to be used in a variety of applications, including motor starters, HVAC systems, circuit protection devices and signal switching devices. This power relay is highly reliable and can handle high-load switching operations while providing accurate signal control.

The HJ2-L-AC220/240V-R power relay is equipped with a contact block containing a single-pole double-throw (SPDT) contact combination. The contact block consists of two sets of Normally Open (NO) and Normally Closed (NC) contacts. The SPDT contact block allows for two distinct switching operations to be carried out, one when the coil is activated and another when the coil is deactivated. This enables the power relay to switch power to two different circuits or devices independently.

The HJ2-L-AC220/240V-R power relay utilizes a form-C contact combination and a minimum operating voltage of 85V. The contact block is designed with silver-tin oxide contacts for maximum switching performance and durability. The power relay also employs built-in surge suppression and overcurrent protection features that help ensure a safe and reliable operation.

The working principle of the HJ2-L-AC220/240V-R power relay is based on the use of an electromagnet. A current is applied to the coil of the power relay when an external power source is connected to it. This creates a magnetic field which causes the connected contact block to move and close or open depending on the state of the coil. When the coil is energized, the contact block will move to the closed position, allowing power to flow through the circuit. When the coil is de-energized, the contact block will move to the open position, effectively cutting off power to the connected circuit.

The HJ2-L-AC220/240V-R is suitable for applications that require high-current power switching and circuit protection. This power relay is designed to remain reliable even under heavy loads and frequent switching operations. It is equipped with built-in surge suppression and overcurrent protection features to ensure a safe operation. Furthermore, the utilization of a single-pole double-throw contact block and its minimum operating voltage of 85V make the HJ2-L-AC220/240V-R an excellent choice for switching and circuit protection applications.
