Key Advantages for Engineers
- Wide 9A-95A current range helps engineers standardize one contactor family across multiple three-phase motor applications.
- AC-3 and AC-4 utilization categories support both standard motor switching and heavier reversing or jogging duty selection.
- IEC/EN 60947-4-1 compliance plus multiple export certifications improve confidence for OEM projects and global industrial panels.
Technical FAQs
How do I select the right NC1 AC Contactor for a three-phase motor?
Selection should be based on the motor rated current, supply voltage, utilization category, and required electrical life. The NC1 range covers 9A to 95A and supports AC-3 and AC-4 duties for different motor control conditions.
What is the difference between AC-3 and AC-4 for the NC1 series?
AC-3 is typically used for normal starting and stopping of squirrel-cage motors, while AC-4 applies to inching, plugging, or reversing duty where switching stress is higher. Engineers should use AC-4 data for more severe motor control cycles.
Can SNTElec support OEM and export supply for NC1 contactors?
Yes. SNTElec supports OEM and export supply for NC1 contactors with multiple coil options, auxiliary contact configurations, and current ratings, helping overseas buyers source compliant motor control components for industrial projects.
