MS-N Series Auxiliary Power Contactor Front Clip-On: Features
UN-AX4 external appearance
- Twin contacts are used for all contacts, attaining high contact reliability.
- Auxiliary contacts can be added to electromagnetic relays and electromagnetic contactors in nearly all series.
- Because these can be added easily without using special tools, it is effective for on-site modifications, etc.
- Thin-type takes up only a small mounting area, greatly contributing to a smaller panel surface area.
- Twin contacts are used for high contact reliability. Applicable to low-level signals.
