SSR relay RSR62-48A40 RSR62-48A40 3-phase 2615963

Three-phase solid-state relay for advanced applications

The RSR62-48A40 solid-state relay is a robust solution for controlling three-phase loads in demanding industrial conditions. Designed by RELPOL S.A., this relay combines reliability, efficiency, and safety, offering an effective alternative to traditional electromechanical relays. Its design based on SCR (thyristor) technology ensures trouble-free operation and long service life, especially in applications with frequent switching.

Characteristics and application

The RSR62-48A40 is designed to switch loads with a voltage of 480 V AC and a current of up to 40 A. Thanks to the ability to choose the control input (90…280 V AC), it can be easily integrated with various control systems. This relay finds application in a wide range of devices and installations, such as:

• Three-phase motor control
• Electric heating
• Industrial lighting
• Automation systems
• Heating and cooling devices
• Industrial machines and equipment

Advantages and benefits

• Zero-crossing switching: Ensures smooth load switching, minimizing electromagnetic interference and extending the life of equipment. This is particularly important when controlling motors, where sudden current surges can cause damage.
• High resistance to interference: Thanks to the optical isolation of the input from the output, the relay is resistant to electrical interference, guaranteeing stable operation in harsh industrial conditions.
• No moving parts: Eliminates the risk of mechanical wear, increasing the reliability and service life of the device. This translates into less frequent inspections and replacements, and therefore – lower operating costs.
• Wide range of control voltages: Enables easy integration with various control systems, regardless of the type of control signal (AC or DC).
• High efficiency: Minimizes energy losses during switching, resulting in energy savings.
• Safety: Built-in RC/MOV protection protects against overvoltage and short circuits, ensuring safe operation of the installation. Test voltage 4000 Vrms guarantees high galvanic isolation.

Additionally, the possibility of mounting on a board or 35 mm rail facilitates installation and integration with existing systems. Made of high-quality materials, it ensures durability and resistance to mechanical damage.
