• ADJ53024 Power Relays, Over 2 Amps - Application Field and Working Principle

• 1. Application Field

  ADJ53024 is a high-current power relay designed for motor control, welding, heavy equipment, and HVAC/industrial controls applications. Its thermal parameters also make it suitable for use in automotive switching applications. ADJ53024 is rated to carry up to 10 amperes continuously with a maximum switching capacity of 24 amperes. Its contact rating of 30 amperes makes it suitable for controlling heavy-duty machinery with high contact loads.

  In addition, the relay’s quick-break contact system greatly reduces electrical noise and arcing across the contact points, which helps reduce shock and vibration when the contact is opened or closed. Its sealed construction makes the relay resistant to moisture and dirt, and it can be used both indoors and outdoors without any additional protection.

• 2. Working Principle

  ADJ53024 has a quick-break contact system that is designed to reduce electrical noise and arcing when the contact is opened or closed. It has a operated closing circuit which is energised when the relay receives sufficient voltage. This releases the mechanical tension on the contact arm, allowing it to close, thus connecting the two contact points. As soon as the voltage is interrupted, the contact arm is quickly released and the contact opens, thus disconnecting the two contact points.

  The relay also has a fail-safe feature which prevents it from becoming locked in the closed position if the voltage is suddenly interrupted. The spring tension of the contact arm is set to ensure that the contact opens even if the voltage is interrupted. This feature prevents damage to the relay and ensures reliable performance over time.
