That 45 A figure is the continuous load current it can switch — sized for a three-phase heater bank drawing that line current, not a motor inrush curve. The 12 to 24 VDC control input is optically isolated via a phototriac coupler, so the PLC or thermostat output sees a low-current DC load while the power side handles the AC heater circuit. The zero-cross function turns on the output only when the AC sine wave crosses zero volts. Operate and release times are each one-half of the load power source cycle plus 1 ms maximum. ## Key electrical ratings at a glance Leakage current is 20 mA maximum at 480 VAC. Output ON voltage drop is 1.8 V RMS maximum. Dielectric strength is 2,500 VAC for 1 minute. Insulation resistance is 100 MΩ minimum at 500 VDC. The yellow operation indicator shows control voltage is present.","metaTitle":"Omron G3PE-545B-2 Three-Phase Solid State Contactor, 45 A, 2","metaDescription":"Omron G3PE-545B-2 three-phase solid state contactor for heaters.
