Model Explanation

NC1-2508:

NC1: Series code of CHNT AC contactors

25: AC-3 rated current of 25A

08: 4-pole main contact configuration, 2НО+2НЗ (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 “З” indicates DC coil)
Add F4 series auxiliary modules when auxiliary contacts are insufficient
