SSR relay RSR72-48A40-H RSR72-48A40-H 1-phase 2616002

Solid State Relay SSR – Reliable Load Control

The RSR72-48A40-H solid state relay is a robust solution for switching AC loads, especially where high switching frequency and long service life are required. This single-phase relay with a built-in heatsink provides efficient heat dissipation, resulting in stable operation even under heavy loads. The use of zero-crossing technology minimizes electromagnetic interference and extends the service life of both the relay and the connected devices.

Construction and Application

The RSR72-48A40-H relay is designed to operate with a load voltage of 480 V AC. The control input accepts a 90…280 V AC signal, making it compatible with a wide range of control systems. The integrated heatsink eliminates the need for additional mounting and ensures optimal operating conditions. Solid state relays of this type are used in control cabinets, automation systems, lighting control systems, and in applications requiring frequent load switching, such as plastics and food processing machinery.
