- Structure & Caratteristiche
- Configurazione del contatto principale: 4-pole design with 2 Normalmente aperto (NO) + 2 Normalmente chiuso (NC) contatti, meeting the requirements of special control circuits
- Coil System: Adopts high-quality electromagnetic materials with low power consumption design, ensuring reliable pull-in and low noise
- Sistema di estinzione dell'arco: High-efficiency arc extinguishing chamber guarantees breaking capacity and extends contact service life
- Contatti ausiliari: Can be expanded with F4 series auxiliary contact modules (ordered separately), up to 4NO+4NC maximum configuration
- Thermal Relay Compatibility: Can be combined with NR2 series thermal overload relays to form an electromagnetic starter, realizing motor overload protection
- Application Scope
- Avvio frequente, stopping and reversing control of AC motors
- Remote switching on and breaking of circuits
- Combination with thermal overload relays to protect circuits prone to overload
- Suitable for various motor control configurations such as DOL (Direct-On-Line) di partenza, star-delta starters and reversible contactors
- Widely used in industrial automation, building electrical systems, power systems and other fields
- Spiegazione del modello
NC1-2508:
NC1: Series code of CHNT AC contactors
25: AC-3 rated current of 25A
