Omron G3NA Series Solid State Relay, 5 A Load, Screw Mount, 264 V Load

Omron G3NA Series Solid State Relay, 5A Maximum Load Current, 264V Maximum Load Voltage - G3NA-205B-UTU AC100-240

This solid-state relay is an electronic switching device designed for control of AC loads in industrial automation and electrical systems. It operates with AC input voltages across a broad range and uses zero-cross switching to reduce electromagnetic interference and stress on connected equipment. The relay is intended for panel or control-board installations where compact, low-maintenance switching is required.

Features and Benefits:

• Handles 5A continuous load for moderate current applications
  Supports AC100–240V input enabling flexible supply use
  Switches up to 264V AC to accommodate high-voltage loads
  Zero-cross switching reduces inrush and electromagnetic noise
  Screw-terminal mounting simplifies secure panel installation
  Low off-state leakage of 10 mA minimises standby current draw

Applications

• Suitable for temperature control systems in manufacturing processes
  Ideal for switching heating elements in lab and industrial ovens
  Used with motor-control circuits requiring EMI reduction
  Can be used for controlling lighting banks in commercial installations
  Suitable for integration into control panels with screw-terminals

What ambient temperature range can it tolerate during operation?

It is rated to work down to −30 °C and up to 80 °C, allowing use in a wide variety of controlled and harsh workplace environments.

How is the device secured within a control panel?

Connections are MADE via screw-type terminals and mounting is designed for fixed panel installation to ensure robust electrical and mechanical contact.

What characteristic limits its use with very low-voltage loads?

The relay requires a minimum load voltage of 19V to switch reliably, so it is unsuitable for applications below this threshold.

Are there approvals relevant to industrial compliance?

It carries recognised approvals from CSA, TUV and UL, supporting acceptance in regulated installations.
