- Structure & Characteristics
- تكوين جهة الاتصال الرئيسية: 4-pole design with 2 Normally Open (لا) + 2 Normally Closed (نورث كارولاينا) اتصالات, 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
- Arc Extinguishing System: High-efficiency arc extinguishing chamber guarantees breaking capacity and extends contact service life
- جهات الاتصال المساعدة: 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
- Frequent starting, 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) starting, star-delta starters and reversible contactors
- Widely used in industrial automation, building electrical systems, power systems and other fields
- شرح النموذج
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 (اللاحقة “ز” indicates DC coil)
- Add F4 series auxiliary modules when auxiliary contacts are insufficient
