ST-REL7 Series, Power Relays, Over 2 Amps

Power relays over 2 Amps are electromechanical devices designed to control the switching of large electrical loads using a smaller control signal. These relays are specifically engineered to handle higher current levels, providing a reliable and efficient solution for applications requiring the control of significant power. The contacts of power relays over 2 Amps are rated to handle various current levels, ranging from 2 A to 750 A. This wide range of ratings allows for flexibility in selecting a relay that matches the specific current requirements of the load being controlled. The available ratings include 2 A, 3 A, 3.5 A, 4 A, 5 A, 6 A, 7 A, 7.5 A, 8 A, 8.5 A, 9 A, 10 A, 11 A, 12 A, 14 A, 15 A, 16 A, 18 A, 20 A, 21 A, 23 A, 25 A, 26 A, 30 A, 31 A, 32 A, 33 A, 35 A, 40 A, 48 A, 50 A, 60 A, 90 A, 100 A, 120 A, 150 A, 200 A, 400 A, and 750 A. These power relays consist of an electromagnet and a set of contacts. When the control signal is applied to the electromagnet coil, it generates a magnetic field that attracts or releases the contacts, allowing the larger load current to flow or be interrupted accordingly. This mechanism enables the safe and reliable control of high-power devices such as motors, heaters, lighting systems, and other industrial equipment. Power relays over 2 Amps are commonly used in various industries, including manufacturing, energy, transportation, and telecommunications. They provide a robust and dependable solution for switching heavy loads, ensuring efficient operation and protection of electrical systems. It's important to select the appropriate power relay with a current rating that matches or exceeds the load requirements to ensure safe and reliable operation. Additionally, factors such as coil voltage, contact configuration (such as normally open or normally closed), and mounting options should be considered when choosing a power relay for a specific application. In summary, power relays over 2 Amps are electromechanical devices designed to control the switching of large electrical loads. They offer a wide range of current ratings, accommodating various load requirements. These relays are widely used in industrial applications where the control of high-power devices is necessary. By providing a reliable and efficient means of controlling significant electrical loads, power relays contribute to the smooth and safe operation of diverse systems and equipment.
