SSR relay RSR62-48A25 RSR62-48A25 3-phase 2615959

Solid State Relay – Reliable Control of Three-Phase Loads

The RSR62-48A25 solid state relay is a robust solution for switching three-phase loads in industrial applications. Designed by Relpol, a leader in relay production, it provides reliable operation and long life, eliminating typical problems associated with mechanical switching elements. Thanks to zero-crossing switching, electromagnetic interference and the risk of damage to connected devices are minimized.

Construction and Application

The RSR62-48A25 relay is designed to work with loads at 480 V AC and a current of up to 25 A. Its semiconductor-based design guarantees quiet operation and no sparking, which is particularly important in environments sensitive to interference. The wide range of applications includes:

• Three-phase motor control

• Switching electric heaters

• Industrial process automation

• Lighting control systems

• Plastics and food processing machinery

Key Features and Benefits

• Zero-crossing switching: Reduces electromagnetic interference (EMI) and extends the life of the load. This means less risk of damage and more stable system operation.

• Three-phase: Ideal for controlling three-phase motors and other loads requiring three-phase power.

• High surge current resistance: Characteristic C allows it to react more slowly to short current spikes, therefore it tolerates starting devices with a motor well.

• No moving parts: Eliminates the risk of mechanical wear, increasing the reliability and life of the device. This translates to less frequent inspections and replacements.

• Wide input control voltage range (90…280 V AC): Ensures compatibility with various control systems. Facilitates integration with existing infrastructure.

• Rated voltage 480 V AC: Allows use in a wide range of electrical installations.

• Rated load AC3 - 25/480 V AC: Specifies the load parameters for which the relay provides optimal operation and safety.
