NewTrend · MC7-U
Product overview
MC7-U modular contactors provide AC/DC-coil switching for building lighting, heating and other low-inductance loads. This page covers the 25A and 63A all-NO versions in two- and four-pole arrangements.
Technical selection summary
| Selectable versions | 25A or 63A AC-1; 2NO or 4NO; AC/DC 230V coil. |
|---|---|
| Motor-load ratings | 25A frame: 9A AC-3; 63A frame: 25A AC-3. |
| Main-circuit voltage | 2P: 250V AC; 4P: 500V AC, as shown in the corresponding technical table and labels. |
| Coil | AC/DC 230V selected here; AC operation 50/60Hz. |
| Mounting | 35mm DIN rail. |
| Protection | IP20 device; IP40 when installed in a suitable distribution enclosure. |
| Ambient temperature | Operating -5 to +60 C; storage -40 to +70 C. |
| Installation spacing | At least 9mm spacing/spacers between adjacent devices as required by the installation illustration. |
| Recognition traceability | UL Recognized Component, file E539285, category NRNT2; factory family BMC7. |
| Model-reference note | MC7-U is the website sales reference obtained by removing the first model letter; the original certification family is BMC7. Recognition applies to the original approved component, not a newly certified renamed model. |
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. UL identification and the exact supplied factory version are confirmed with the quotation. UL Recognized Component is distinct from UL Listed equipment.
Typical applications
- Lighting and resistive-heating control in building distribution boards.
- Ventilation, pumps and small motors when selected for the actual utilization category.
