Contacts, Spring Loaded and Pressure

XP3A-5866-0770D-R/S is a contact device consisting of a movable contact and a fixed contact which can be controlled by the action of external force or energy and can establish or cut off an electrical circuit. Typical components include silver alloy contacts, phosphor bronze terminals, double ended springs, nitrile rubber pressure gaskets, and an isolation chamber. It is designed to protect wires and electrical components from short circuits and overcurrents.

Application Field

XP3A-5866-0770D-R/S is used for a wide variety of applications, including high current motor control applications, high-voltage power supplies, UPS systems and medical equipment. The device offers a robust design, high current and voltage rating and reliable contact performance. It can be used in a wide range of temperature and humidity conditions; it is suitable for both indoor and outdoor use.

Working Principle

XP3A-5866-0770D-R/S consists of two contacts, each of which is supported by a piston in a pressure chamber, or two contact pistons; the contact pressure between the two pistons produces the electrical connection when the contacts close. The contact pressure is controlled by means of a double-ended spring which compresses against one of the contact pistons, while the other contact piston remains stationary. This allows the contact pressure to be adjusted to provide a secure and reliable electrical connection.

When the contact pressure is released, the contacts open, and the electrical circuit is broken. The contact pressure is maintained by a nitrile rubber pressure gasket which provides additional insulation and helps to keep the contacts closed under extreme temperature and humidity conditions. The isolation chamber helps to protect the contacts from environmental contaminants. Additionally, the design of the device ensures that it will perform reliably in a wide range of applications.

XP3A-5866-0770D-R/S is extensively used in industrial, commercial and consumer applications, due to its robust design, high current rating and long-term reliability. It is designed to perform reliably in extreme temperature and humidity conditions and offers protection from short circuits and overloads. The device is easy to install and maintain and can be used in a variety of applications.
