Power Relays, Over 2 Amps: RR3P-UAC240V Application Field and Working PrinciplePower relays are electrical control components that use electrical signals to power electrode circuits and control multiple circuits at the same time. The RR3P-UAC240V is an AC hydraulic overload protection relay specifically designed for a variety of industrial applications. It is a three-phase overload relay, designed to provide reliable overload protection for electrical motors and pumping systems.Application FieldThe RR3P-UAC240V can provide reliable overload protection for all types of three-phase motors, including AC motors that operate on low- or high-voltage AC supplies from 100 to 600V. It is suitable for use in a range of industrial applications with high-power leveling, such as water pumps, cranes, compressors, conveyors, hoists, fans, mixers, and other machinery powered by electric motors. The setting range of the device, adopting the three-phase setting detection technology, is relatively wide compared to the other overload relays in its class, which makes it suitable for all types of motor load.Working PrincipleIn order to realize the overload protection feature of the device, the RR3P-UAC240V has a thermal capacity-time characteristic. When the current of the motor reaches the setting value of the device, the internal heating of the motor will increase, causing the device to trip. For three-phase motors, the device detects the current of each phase, and calculate the average value to determine whether it reaches the setting value.The RR3P-UAC240V is designed with a manual reset function, wherein the release button resets the device after it has been shut down due to an overload event. The reset button is protected by an enclosure to prevent accidental tripping.The setting range of the device is wide, ranging from 3.5 to 17 Amps. The device comes with multiple national-standard sources, such as European CEE7, British BS 3309, and North American ANSI C-37, which makes it compatible with a wide range of voltage levels and frequencies.It is also an intelligent device, supporting remote-controlled modification of settings and current detection. In addition, a friendly Chinese-character display panel is provided on the device, making it easy to operate.In terms of reliability, the integrated heater element adopts heavy-load silver-film technology, with an operation life of up to 100,000 operations. In addition, the enclosure is of the IP20 rating, which offers protection against dust and splashing water.The RR3P-UAC240V is equipped with a miniaturized structure, allowing it to be installed in tight spaces. At the same time, the device is designed to be energized at the rated voltage 60 times per minute, allowing it to remain in a constant operational state.Overall, the RR3P-UAC240V overload relay is a reliable, efficient, and easy-to-operate device, suitable for use in a wide range of applications, and is ideal for industrial applications with high-power leveling.
