The Omron G3PE-535B-3N DC12-24 is a three-phase solid state contactor from the G3PE series, designed specifically for heater loads. It is rated for 35 A at 200 to 480 VAC, with a control input of 12 to 24 VDC. The zero cross function ensures switching occurs near the voltage zero crossing, minimizing inrush current and electrical noise — a practical advantage when cycling resistive heater elements in industrial ovens or packaging machinery.
The 35 A rating at 200-480 VAC is the continuous load current for resistive heater duty — do not derate for motor or inductive loads without checking the datasheet's AC-51 or AC-53 curves. The operating voltage range of 180 to 528 VAC gives headroom for nominal 400 VAC three-phase systems with typical line variation. The phototriac coupler isolation provides galvanic separation between the 12-24 VDC control side and the power circuit, which simplifies interfacing with a PLC or temperature controller. A yellow operation indicator gives a quick visual check during commissioning.
