Product overview
CH8-M contactors combine an AC-coil modular contactor with a front manual control lever. This page covers 4P all-NO versions in 25A and 63A frames.
Technical selection summary
| Rated current | 25A or 63A. |
|---|---|
| Contacts | 4NO |
| 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 selected here | AC 230V selected from the source product-page example; confirm the supplied manual-control version coil marking with the quotation. |
| Operation | Front manual-control lever; exact operating positions and reset behavior should match the supplied version. |
| Mounting | 35mm DIN rail. |
| Dimensions | Use the manual-control drawing, which includes the projecting control; do not substitute the standard-contact version depth. |
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.
