2903302

Power Relays, Over 2 Amps

The 2903302 is a power relay that is used for remote switching applications. It is designed to control circuits with up to 16A at 100-277VAC. This type of power relay is commonly used in industrial and residential applications, such as lighting, HVAC, and small motors.

The 2903302 power relay is based on a solenoid electromagnet, which is a coil of wire wrapped around a ferromagnetic core. When the current flows through the coil it generates a magnetic field, which attracts the movable armature inside the relay, closing the circuit. The amount of current needed to activate the relay depends on the type of relay and its coil resistance.

The 2903302 power relay is designed with a single pole double throw (SPDT) contacts, meaning that it has two separate circuits that can be controlled by the relay. It also has a status LED to indicate the state of the relay, either open or closed. The contact rating is 16A at 277VAC for resistive loads, and 5A at 277VAC for inductive loads.

This type of power relay can be used in a wide range of applications, including motor control, HVAC systems, lighting systems, access control, security alarms, and more. It is also suitable for use in hazardous areas, as it is designed to meet UL, CSA, and CE requirements. The 2903302 power relay is a reliable and cost-effective way to switch circuits.

When using the 2903302 power relay, it is important to ensure that the relay is rated for the correct voltage and current. Over-current or overload can cause damage to the relay and may cause a fire or other safety hazard. Installers should also ensure that the control circuit is properly wired to the relay.

The 2903302 power relay is an effective and reliable switching solution for a wide variety of applications. Its SPDT contact design and status LED make it easy to monitor the state of the relay. With its high current and voltage rating, the 2903302 is an ideal solution for motor control, HVAC, lighting, and access control applications.
