Datasheet - G3NA-250B-UTU 100-240VAC

COO (Country of Origin):: CN

Omron G3NA-250B-UTU 100-240VAC Series Solid State Relay, 50A Maximum Load Current, 240V Maximum Load Voltage - G3NA-250B-UTU 100-240VAC

This solid-state relay provides reliable on-off control for AC loads in industrial automation and electrical systems. It accepts a low-voltage control signal and switches alternating current without mechanical contacts, enabling silent operation and reduced wear. The unit is intended for surface mounting in control panels and machinery where high-current switching and a Compact footprint are required.

Features and Benefits:

• Supports 50 A load current for high-current AC switching
• Operates up to 240V AC enabling broad supply compatibility
• Accepts 5 V-24V control for flexible input interfacing
• Low off-state leakage of 5 mA or 10 mA reduces standby dissipation
• On-state resistance around 100 mΩ minimises conduction losses
• Rated for use between -30 °C and 80 °C for varied environments

Applications

• Suitable for controlling industrial heaters and ovens
• Ideal for motor controller auxiliary circuits
• Used with lighting banks in large installations
• Can be used for AC distribution switching in panels

What Terminal style is provided for electrical connections?

Screw-type terminals are used for the output and control connections to allow secure cable fastening.

How is the unit mounted in a control enclosure?

It is designed for surface mounting, enabling attachment to flat-panel or DIN-compatible surfaces.

What switching configuration does it implement?

It employs a single-pole single-throw normally open arrangement for simple on-off control.

Which standards and approvals apply to its construction?

The component conforms to multiple safety and installation standards including UL, CSA, EN/IEC 60335, IEC 60715 and TÜV.
