- Model Explanation
NC1-2508:
NC1: Series code of CHNT AC contactors
25: AC-3 rated current of 25A
08: 4-pole main contact configuration, 2NO+2NC (08=2NO+2NC, 04=4NO, 00=4NC)
- Selection Tips
- Select the appropriate model according to load type (AC-3/AC-4) and rated current
- Ensure the control circuit voltage matches the coil voltage
- Select NC1-2508Z model if DC coil is required (the suffix “Z” indicates DC coil)
- Add F4 series auxiliary modules when auxiliary contacts are insufficient
