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.

- Note: When being used with T65, T80, N50 or N65, the auxiliary terminal screw size for the T65, T80, N50 or N65 main body is M4. For the auxiliary contact unit, the terminal screw size is M3.5. Different screw size prevents interchangeable use.
- The front clip-on type and the type mounted on the side cannot be mounted and used on the same main body.
- UN-AX□CX is the type name having a CAN terminal.
- When mounting auxiliary contact unit UN-AX2/AX4, live part protection cover UN-CV250, CV251 cannot be mounted.
