Product specifications
| Item | Contact form | Contact rating | Electrical durability | Mechanical durability | Coil voltage | Coil power consumption | Ambient temperature | Safety standard certification |
| Spec | SPST-NO (1a) | 480 VAC / 36 A |
|
1,000,000 operations min. (switching frequency: 18,000 operations/h) | 12 VDC | Approx. 1.4 W 172 mW*2 |
-40 to +85°C | C-UL*3 / UL / TUV / CQC IEC60079-15 explosion-proof certified |
|---|
*1. According to OMRON's research in February 2024. Comparison of maximum rated catalog values of relays with IEC60079-15 explosion-proof certification.
*2. When holding voltage is 35%.
*3. However, C-UL certification is not applicable to 480 VAC rated products.
