The G3PB-535B-2N-VD is a three-phase solid state contactor from Omron's G3PB series, rated for 35 A load current on a 200 to 480 VAC main circuit. It's built for switching resistive heater loads in industrial ovens, packaging seal bars, and process heating zones where mechanical contactor wear is a problem. The DIN track mounting and integrated heat sink (the 'N' suffix) mean it clips onto a standard rail and sheds heat without an external heatsink — saves panel space and one assembly step.
The 35 A rating is for a Class-1 AC resistive load (heater), which translates to 29.0 kW max at 480 VAC three-phase. That's the number to match against your heater bank nameplate — if the load draws 38 A steady-state, this unit is undersized. The 200-480 VAC range covers common global line voltages, but note it's a 2-element control scheme (switching two phases; the third passes through), which is standard for three-phase resistive loads. Leakage current sits at 20 mA at 480 VAC — enough to ghost a small pilot light if the load is high-impedance; factor that into your circuit design. The zero-cross function turns on at the voltage zero point, which minimizes inrush and RFI — good for heater loads but not for inductive loads like transformers, where random-switch SSRs are preferred.
Screw terminals (B-type) accept standard ring or fork lugs — no special crimp tool needed. The DIN rail mount (N-type) snaps onto a 35 mm rail; the built-in heat sink is sized for the 35 A rating, so no extra derating for enclosure height. Vibration resistance is 0.175-mm amplitude at 10-55 Hz when mounted to DIN rail — adequate for panel-mounted gear but not for direct machine mounting. Shock resistance is 294 m/s² (destruction), dropping to 98 m/s² if reverse-mounted; keep the orientation per the manual for full shock rating.
