Power Relays, Over 2 Amps

Power relays over 2 amps are electromechanical switch devices that enable an electrical signal to control an electrical circuit. Consisting of an input coil, the coil energizes when electric current is applied and a contact closes when enough current passes through the coil. The contact will remain closed until the current is removed and the magnetic field collapses. Commonly used in industrial settings, power relays over 2 amps find applications in electric motors, HVAC equipment, lighting, and numerous industrial equipment.

5-1617785-2 Application Field and Working Principle

The 5-1617785-2 Power Relay is rated at 16A and 277VAC. It is suitable for commercial, industrial, and light-commercial applications. The relay is designed for a range of high-voltage applications, including controlling electric motors, pumps, valves, and other equipment. It is also suitable for controlling heating, ventilation, and air-conditioning (HVAC) systems as well as domestic applications such as traffic signals and fire alarm systems.The 5-1617785-2 Power Relay is energized by a voltage input and switches depending on the state of the input. The input is either switched off or on by a manual or automated switch, sending the signal through the winding of the relay. When the input is “on”, current runs through the winding to produce a magnetic field; this field pulls down the armature which, in turn, depresses a button on the switch contacts. When the input is "off", the armature returns to its original position, opening the contacts. This action may be used to switch circuits on and off. The contacts can be used to control loads up to 16A and 277VAC. The 5-1617785-2 Power Relay also features a hold-in feature, which helps ensure the switch contacts remain closed even when power to the coils is removed temporarily. This is done by the application of a certain "holding" voltage that "holds" the armature in place until the input conditions are changed. The 5-1617785-2 also has an overload safety feature that prevents a short-circuit condition from damaging the relay switch by limiting the current through the input winding. Power relays over 2 amps are widely used in industrial settings as they offer a reliable and cost-effective solution for controlling and switching electric circuits. The 5-1617785-2 Power Relay is a reliable and versatile switch used in high-voltage applications and offers a robust and dependable solution.
