Omron G3PE-225B-3N | Omron | Solid State Contactors for Three-phase Heaters

Description

The G3PE-225B-3N is a high-performance three-phase solid state contactor designed specifically for controlling industrial heating loads. Utilizing a phototriac coupler for insulation, this solid state relay (SSR) provides rapid, maintenance-free switching without the wear associated with mechanical contactors. The unit features an integrated zero cross function, which minimizes inrush current and electromagnetic interference during switching, protecting the heater elements and prolonging system lifespan. Optimized for high-density industrial control panels, it supports DIN track mounting and provides reliable operation for three-phase heater applications requiring a 25 A load capacity.

Installation Guidelines

• Mounting: Ensure the device is mounted on a standard DIN rail in a vertical orientation to facilitate natural convection cooling.
• Heat Dissipation: Solid state contactors generate heat during operation. Maintain adequate clearance from other components to ensure sufficient airflow.
• Wiring: Use appropriately sized conductors for the 25 A load. Ensure all terminal connections are tightened to the torque specifications provided in the installation manual.
• Protection: It is recommended to install a fast-acting fuse in series with the load to provide short-circuit protection for the output semiconductors.
