Power relays are auxiliary electronic switching devices used to switch current of a specific value or voltage. HJ4-AC120V-R-6 power relays can be classified as Over 2 Amps power relays. These relays are used to control circuits with current at or above 2 Amps.

The HJ4-AC120V-R-6 power relay uses a mechanical switch composed of an armature to connect and disconnect power from a circuit. The armature is shifted between the contact points of the relay terminals when a voltage is applied to the relay coil. In general, the current supplied to the relay should not exceed the rated current of the relay.

The working principle for HJ4-AC120V-R-6 power relay is simple. When a voltage is applied to the relay coil, it induces a magnetic field around the coil. This magnetic field pulls the armature towards the coil, which mechanically shifts the armature between the contact points of the relay terminals, thus completing the circuit and allowing current to flow through the circuit. When the voltage is removed from the coil, the magnetic field is removed, and the armature is shifted back to its original position, thus disconnecting the contact points of the relay and turning the circuit off.

HJ4-AC120V-R-6 power relays are used in a variety of industrial and commercial applications. These relays are often used to control high-power motors and circuits, such as those found in industrial machinery and large appliances. They can also be used to control heating elements, lights, pumps, fans, and other electrical devices with current, voltage, or power requirements that exceed the rating of a general-purpose relay.

HJ4-AC120V-R-6 power relays are designed to be durable and reliable. The contacts are resistant to corrosion, arcing, and other forms of damage, and are designed for repeated switching applications. The relays are made with high-quality insulators to ensure that the contacts remain securely insulated from the coil. The relay also includes built-in protection features, such as over-current and over-voltage protection, to ensure the safety of the circuit.

HJ4-AC120V-R-6 power relays are a dependable and reliable way to control and switch high-power circuits and motors. The simple design combined with the built-in protection features make these relays suitable for a variety of industrial and commercial applications.
