Omron G3PE-535B-2N 3-Phase Heater Control (Solid State Relay)

Description

The G3PE-535B-2N is a robust, compact 3-phase solid-state relay (SSR) designed specifically for high-efficiency heater control in industrial applications. By utilizing a phototriac isolation method, this unit ensures complete electrical separation between the control signal and the high-voltage load, providing safe and reliable switching for heating elements.

This model is engineered for heavy-duty performance, supporting a 35A load current and a wide load voltage range of 200 to 480 VAC. A critical feature is the integrated zero-cross function, which minimizes electrical noise (EMI) by switching the output only when the AC voltage crosses zero, thereby extending the life of both the heater and the relay. With its screw terminal structure and high inrush current resistivity, the G3PE-535B-2N is a dependable choice for industrial heating processes.

Installation Guidelines

• Heat Dissipation: Due to the 35A current capacity, ensure the relay is mounted on a heat sink or in an area with sufficient airflow. SSRs generate heat during operation, and proper cooling is essential to prevent thermal failure.
• Wiring: Use appropriately rated cables for the load side to handle 35A continuously. Ensure all terminal screws are tightened to the specified torque to prevent overheating at the connection point.
• Safety: Since the load voltage can be as high as 480 VAC, ensure the system is properly grounded and that protective covers are installed over terminals to prevent accidental contact.
• EMI Considerations: Although the zero-cross function significantly reduces electrical noise, keep low-voltage control signal wiring physically separated from high-voltage load wiring to maintain signal integrity.
