Description
Omron G3PE-545B-3 DC12-24 Three-Phase Solid State Contactor
The **Omron G3PE-545B-3 DC12-24** is a three-phase solid state contactor designed for electronic ON/OFF switching of compatible AC loads. Unlike conventional electromechanical contactors, it uses semiconductor switching technology, making it suitable for applications requiring frequent switching and reduced mechanical contact wear.
This model accepts a 12–24V DC control signal and switches three-phase AC loads within its specified operating range. Its integrated heat sink, screw terminals, LED operation indicator, and protective terminal cover support installation in suitable industrial control systems.

Features and Benefits
Three-Phase Solid State Switching
The three-pole configuration supports simultaneous control of compatible three-phase AC loads from a DC control signal.
12–24V DC Control Input
The wide control-input range supports compatible control circuits using 12V or 24V DC. Verify the available control voltage before installation.
Zero-Cross Switching
The zero-cross function switches the AC output near the voltage zero crossing, helping reduce switching-related electrical disturbance in suitable applications.
Integrated Heat Sink
The heat sink helps dissipate heat generated during operation. Proper mounting, ventilation, and thermal design are essential, particularly at higher load currents.
LED Operation Indicator
The indicator provides a visual reference for control operation and assists with inspection and troubleshooting.
Screw Terminals and Protective Cover
Screw terminals provide secure electrical connections when installed correctly. The terminal cover helps protect against accidental contact with live terminals.
Typical Applications
The Omron G3PE-545B-3 may be suitable for compatible applications such as:
– Industrial electric heating systems
– Three-phase resistive heating loads
– Temperature-control equipment
– Industrial process heating
– Automated machinery with compatible AC loads
– Electrical control panels
Confirm that the load type and operating conditions are supported before selecting the contactor.
Installation and Compatibility Guidance
Before installation, verify the full model number, DC control voltage, three-phase AC supply, load current, and wiring diagram. The 45A rating applies under specified conditions and should not be treated as a universal rating for every installation.
Solid state contactors generate heat during operation and may require thermal derating. Install the unit according to Omron’s mounting and ventilation requirements, and select appropriate overcurrent protection and heat-management measures for the application.
This device is intended for ON/OFF switching; it is not a variable-speed drive or a general-purpose motor starter replacement without application-specific engineering review.
