This document introduces the features and characteristics of the G3NA solid state relay, including increased load current, unified installation spacing, external surge absorption effect, action indicator light, and protective cover. The product is suitable for loads ranging from 5A to 90A.
The Omron G3NA series solid‑state relays are general‑purpose SSRs with load ratings from 5 A to 90 A. The manual provides product selection guidance, common precautions, technical data, wiring diagrams, and installation instructions for DIN‑rail and direct mounting.
Key topics include load‑current versus temperature curves, heat‑sink selection, UL/CSA/EN certifications, and recommended wiring practices. The document also lists optional accessories such as single‑touch mounting plates and various heat‑sink models. This manual is written in Chinese.
| Applicable load current | 5 A – 90 A |
|---|---|
| Isolation resistance | ≥ 100 MΩ (DC 500 V test) |
| Operating temperature range | -30 °C – +80 °C |
The G3NA series is certified by UL, CSA, and EN (TÜV) standards.
When a heat‑sink is installed, reduce the load current by about 30 % according to the load‑current‑temperature graph.
Use the single‑touch mounting plate R99‑12 to attach the G3NA to a DIN‑rail before securing it with screws.
