Power Relays, Over 2 Amps

The XT424730 is an industrial relay designed to provide reliable switching performance at higher currents. It is rated for up to 150A DC or 250A trip in AC load currents, making it one of the most reliable power relays available. The XT424730 offers several features designed to increase its switching capability and reliability, such as a unique contact construction that eliminates the need for an additional switch, a high-transition-temperature (HTH) coil, and a long-lasting mechanical structure that protects the contacts from corrosion and heat generated by a high load current.

Application Field

The XT424730 is designed to be used in a variety of applications that require reliable switching of high currents. Its compact size and high-performance characteristics make it well-suited to use in electrical applications such as starter motors, hydraulic power systems, and large industrial machinery. It is also suitable for remote control and automation applications, and can be used for controlling solenoids, valve actuators, and winches. Additionally, the XT424730 can be used in semi-automated industrial processes where precision control of high currents is necessary.

Working Principle

At the heart of the XT424730 is its unique contact construction, which ensures reliable switching of higher currents than what is found in other power relays. The contact construction consists of a series of individual contact elements which are connected in parallel, and each of these contacts has a dedicated coil that creates an electromagnet. When a current flows through the coil, it produces a magnetic field, which creates a force that moves the contacts. This movement is then transferred to the relay lever, which when shifted, causes the contact to open or close, depending on the direction of the current. This versatile structure allows for various configurations, such as normally open, normally closed, and latching, which are commonly used in industrial control applications.

Additionally, the XT424730 is designed with a high-transition-temperature coil, which is capable of withstanding high temperatures generated by a large load current. This feature significantly enhances the reliability and longevity of the relay, since it eliminates the possibility of an internal short circuit or electrical arc due to excessive heat.

The XT424730 also features a robust mechanical structure, which is designed to provide superior protection for its contacts from both corrosion and heat. This advanced design also allows for faster switching of higher currents than is possible with other power relays.

The XT424730 is a reliable, high-performance relay that can be used in a variety of industrial control applications. Its compact size and high-performance characteristics make it well-suited for use in starter motors, hydraulic power systems, and large industrial machinery. Furthermore, its unique contact construction and high-transition-temperature coil ensure reliable switching of higher currents, and its robust mechanical structure provides superior protection against corrosion and heat.
