Product overview
CH8 modular AC contactors switch building lighting, heating and other distribution-board loads. This page groups the 4P all-NO versions with 25A, 63A and 100A ratings.
Technical selection summary
| Selectable current | 25A, 63A or 100A for the selected all-NO configuration. |
|---|---|
| Main contacts | 4NO; other arrangements require separate confirmation. |
| Rated operating voltage | 400V AC for the 4P versions, as marked on the corresponding product photographs. |
| Rated insulation voltage | Ui 500V AC in the series technical data. |
| Operating conditions | Ambient -5 to +60 C; installation altitude up to 2000m. Use the specified side spacers in distribution enclosures. |
| Mechanical / electrical endurance | At least 1,000,000 / 100,000 operations in the source product description. |
| Short-circuit protection | The contactor does not interrupt short-circuit current; provide a correctly selected protective device. |
| Coil | AC 230V, 50/60Hz for the photographed versions. |
| Load category | Select resistive and motor duty separately; a current rating alone does not establish motor capacity. |
| Mounting | 35mm DIN rail. |
| Standards stated in source | IEC/EN 61095 and IEC 60947-4-1; no UL claim is made for this series here. |
Series reference image. The supplied rating, contact arrangement and coil voltage must match the selected configuration; motor loads require utilization-category selection rather than the resistive-current value.
Typical applications
- Lighting and resistive-heating control in building distribution boards.
- Ventilation, pumps and small motors when selected for the actual utilization category.
