Omron G7J Series Power Relay, 120V Coil Voltage, 25A Switching Current - G7J-4A-T 100/120VAC


This power relay is a Compact electromechanical switching device designed for control and automation panels, providing reliable circuit switching in industrial environments. It is intended for applications requiring a moderate Coil input and high-contact switching capability, suitable where a tab-terminal mounting and a W‑bracket fitment are preferred.

Features and Benefits:


• 120V AC Coil rated at 2.6VA for predictable Coil consumption
• Four single-pole contacts enabling simultaneous switching of multiple circuits
• Silver-alloy contact faces to reduce contact wear and improve conductivity
• Switching capability of 25A for handling substantial load currents
• Can switch AC up to 250V and DC up to 125V for versatile load types

Applications


• Suitable for motor control contact switching in automation panels
• Ideal for interfacing control logic with high-current loads
• Used for switching heater circuits in industrial equipment
• Can be used for load transfer in power distribution modules

What Terminal and mounting methods are used for installation?


Connections are provided via straight tab terminals while the relay body is secured using a W‑bracket mount to suit panel assemblies.

How does the relay perform across temperature ranges?


It operates over an ambient span from −25°C up to a maximum of 60°C, allowing use in typical industrial indoor environments.

What approvals cover its safety and regulatory acceptance?


It carries underwriter and certification approvals recognised in North America, indicated by UL and CSA listings.

What is the electrical contact resistance and how does it affect performance?


Contact resistance is specified at 100 mΩ, minimising voltage drop across closed contacts for efficient current transfer.
