COO (Country of Origin):: CN

Omron G3NA-275B-UTU-2 100-240VAC Series Solid State Relay, 75A Maximum Load Current, 240V Maximum Load Voltage - G3NA-275B-UTU-2 100-240VAC

This solid-state relay is an electronic switching device designed to control AC loads in industrial automation and electrical systems. It accepts a low-voltage control input and switches alternating current without moving parts, providing silent operation and extended service life for high-current applications within typical industrial temperature ranges.

Features and Benefits:

• 75A load capacity for handling high-current circuits • 100-240VAC load voltage range for broad AC compatibility • 24V maximum control input enabling standard control interfaces • Zero-cross switching reduces electrical noise during switching • Low on-state resistance 100mΩ minimises power dissipation • Off-state leakage 5mA-10mA aids accurate low-load behaviour

Applications

• Suitable for motor control panels in factory automation • Ideal for heating element switching in process equipment • Used with AC power distribution modules in control cabinets • Can be used for lighting control in large commercial installations

What Terminal arrangement does it offer for wiring?

It uses a single-pole single-throw normally open contact arrangement with screw-type terminals for both control and load connections.

What mounting method should be used in a control enclosure?

The unit is designed for surface mounting to panels or heatsinks to facilitate thermal management during continuous high-current operation.

What environmental temperature range can it withstand during use?

The device operates between -30°C and 80°C, supporting installations that experience cold starts and elevated ambient temperatures.

How does the input control range affect Interface options?

The control input accepts voltages from 5V minimum up to 24V maximum, allowing direct drive from common PLC outputs and industrial control circuits.
