SSR relay RSR62-60D25-R RSR62-60D25-R 3-phase 2615975

Solid State Relay – Reliable Control of Three-Phase Loads

The RSR62-60D25-R solid state relay is a robust solution for switching three-phase loads on and off. Designed to operate at 600 V AC, it offers instantaneous switching, which is crucial in applications requiring a fast response. Its semiconductor-based construction ensures high durability and resistance to mechanical damage, eliminating problems associated with traditional electromechanical relays.

Construction and Practical Application

This relay is particularly useful in industrial automation systems, where control of motors, heaters and other high-power devices is required. A 4-32V DC control input ensures compatibility with a wide range of PLCs and logic circuits. The lack of a built-in heatsink requires the use of additional cooling – a dedicated RTP-30 thermal pad mounted between the relay and the heatsink, which ensures optimal heat dissipation and stable operation. This solution allows for flexible adaptation of the cooling system to specific working conditions and space limitations.

Key Features and Benefits

• Instantaneous switching: enables quick start-up of devices, which is important in processes requiring precise time control.
• Three-phase circuit: ideal for controlling three-phase motors and other loads requiring three-phase power.
• Wide control voltage range (4-32V DC): ensures compatibility with various control systems.
• High resistance to interference: thanks to its semiconductor construction, the relay is less susceptible to electromagnetic interference than traditional relays.
• No moving parts: increases the durability and reliability of the device, reducing the risk of failure due to mechanical wear.
• Use of RTP-30 thermal pad: allows for efficient heat dissipation, ensuring stable operation even under high loads.
• AC3 rated current - 25A: enables control of loads up to 25A at 600V AC.
