Omron G3PE-245B 12-24VDC Three-Phase SSR: Technical Guide, Applications and Installation
When a machine has to run 24/7, component selection is not about saving a few euros on the BOM — it is about selecting items that will not become a production problem. The Omron G3PE-245B 12-24VDC Three-Phase SSR (24V DC) is designed precisely for that reality, with large industrial heating systems at the top of its application list.
For projects where sensing and switching decisions need to be made together, Omron’s Omron Sensor products are a natural companion to this unit. Both families are built to the same quality standards and documented to the same CE and UL requirements, which simplifies the declaration of conformity process.
About the Omron G3PE-245B 12-24VDC Three-Phase SSR
The Omron G3PE-245B 12-24VDC is a Three-Phase SSR rated at 24V DC, built to handle large industrial heating systems reliably over a long service life. Key engineering features include 45 a high current, integrated heatsink, and the unit mounts via din rail.
The engineering case for the Omron G3PE-245B 12-24VDC Three-Phase SSR rests on a clear set of advantages: 45 a high current, integrated heatsink. Operating voltage of 24V DC slots neatly into most European and global panel designs.

Industry Use Cases
The Omron G3PE-245B 12-24VDC Three-Phase SSR is commonly specified for the following applications:
- Large industrial heating systems
- 3-phase process control
Across these use cases, the consistent thread is a need for dependable switching over a large number of operations, often in environments where an unplanned fault would create significant disruption. The Omron G3PE-245B 12-24VDC is designed with exactly those conditions in mind.
Installation Checklist
One underrated aspect of working with Omron components like the G3PE-245B 12-24VDC Three-Phase SSR is the consistency of the mounting system. If you have installed any other unit from the same family, the process is identical — same rail, same socket dimensions, same terminal layout. That repeatability genuinely speeds up panel assembly in high-volume projects.
For ongoing maintenance, periodically inspect for contact discolouration, check terminal screws for loosening, and look for any signs of heat stress on the housing. Catching these early avoids the much larger cost of an unplanned production stop.
Omron G3PE-245B 12-24VDC: Long-Term Value
Omron’s reputation in automation did not come from clever advertising. It came from decades of components performing reliably in factories, warehouses, and process plants around the world. The G3PE-245B 12-24VDC Three-Phase SSR is a current embodiment of that engineering culture — nothing superfluous, nothing compromised.
Frequently Asked Questions
What is the difference between the Omron G3PE-245B 12-24VDC and a mechanical contactor?
The Omron G3PE-245B 12-24VDC Three-Phase SSR is designed for panel-level signal and load switching at the current ratings specified. A contactor is built for direct motor starting at higher currents. For applications within the rated capacity of the Omron G3PE-245B 12-24VDC, it offers faster switching, longer life, and a smaller footprint than a contactor.
How does temperature affect the Omron G3PE-245B 12-24VDC?
Like all electromechanical devices, performance can be affected at the extremes of the operating temperature range. The Omron G3PE-245B 12-24VDC is rated for use across a defined ambient temperature range — consult the datasheet for precise limits and any derating requirements at elevated temperatures.
Can I mount multiple Omron G3PE-245B 12-24VDC units side by side on a DIN rail?
Yes. The Omron G3PE-245B 12-24VDC Three-Phase SSR is designed for standard DIN rail assembly with adjacent units. Ensure adequate total load current is within the rail and busbar capacity, and that enclosure ventilation is sufficient for the combined heat dissipation.
Does the Omron G3PE-245B 12-24VDC include a test facility?
Depending on the model variant, some Omron relay sockets include a manual test button or push-to-test function. Check the specific socket model specified for the Omron G3PE-245B 12-24VDC to confirm whether this feature is available.
How long is the warranty on the Omron G3PE-245B 12-24VDC?
Omron provides a standard 12-month manufacturer warranty on products purchased through authorised distributors. Extended warranty options may be available — contact your local Omron distributor for details.
