Anam Legrand Pak-4sr22 Magnetic Relay

What is an Anam Legrand Pak-4SR22 Magnetic Relay?

The Pak-4SR22 is manufactured by Anam Legrand Co., Ltd. and is a strong magnetic relay for heavy-duty AC applications. It is an electromechanical switching device that primarily operates through the use of magnetic force for opening and closing electrical contacts. This prevents overload, allows for controlled switching, and provides better protection of the system.

Designed to handle high voltage, the relay has an AC 440V 5A load while offering auxiliary contact configurations such as 2a2b, which are widely applied in control systems, motor operations, and automated machinery. With the coil voltages of 208-220V at 50Hz and 220-240V at 60Hz, it provides versatile performance across different power systems.
