Omron G3PA Series Solid State Relay, 30 A Load, DIN Rail Mount, 440 V ac Load, 30V Control

This solid-state relay is a DIN-rail mount switching device designed to control AC loads in industrial automation and electrical systems. It accepts a low-voltage DC control input and provides silent, contactless switching of alternating current with a zero-cross switching function for reduced electrical noise. The unit is suitable for installation in control panels where screw-terminal connections and standard approvals are required.

• Controls up to 30A for high-current switching capability
• Operates across 180–440 VAC to support high-voltage loads
• Accepts 1–30V control for flexible input drive range
• Zero-cross switching reduces inrush and EMI during switching
• Off-state leakage of 20 mA minimises residual current draw
• Rated for −30 °C to 80 °C for wide operating temperature range

• Suitable for resistive heater control in manufacturing processes
• Ideal for motor control in material-handling equipment
• Used with power distribution boards in assembly-line panels
• Can be used for lighting control in industrial facilities
• Suitable for interfacing PLC outputs to high-voltage loads

It provides screw terminals for both control and load connections to facilitate secure, tool-tightened wiring.

The unit is designed for DIN-rail mounting to allow quick installation and standardised panel organisation.

It holds CSA, VDE and UL approvals, demonstrating conformity to recognised safety and performance standards.

Zero-cross operation ensures conduction begins near the AC waveform zero point, reducing switching transients and stress on loads.

The device implements a single-pole single-throw normally open arrangement suitable for on/off AC switching tasks.
