The NC1 Series AC Contactor is a globally trusted solution for frequent starting and controlling of AC motors, as well as managing resistive and inductive loads in HVAC and industrial automation. Designed for high-cycle reliability, the NC1 series is capable of making and breaking circuits remotely and can be combined with thermal overload relays to form a complete magnetic motor starter.

Whether you are looking for a replacement for an existing CHINT NC1 unit or a high-performance equivalent for a new control panel, our NC1 series offers a robust design that excels in demanding environments. With a wide range of coil voltages (from 24V to 660V) and current ratings, it is the most versatile choice for modern power distribution.

• High-Conductivity Silver Alloy Contacts: Engineered with premium silver-cadmium oxide contacts that resist arc erosion and prevent contact welding, ensuring a mechanical life of up to 10 million cycles.

• Versatile Coil Voltage Options: Available in a full spectrum of control voltages (AC 24V, 110V, 220V, 380V, 480V), making it compatible with various regional power standards and control circuit requirements.

• Modular Auxiliary Configurations: Standard models come with built-in auxiliary contacts (10 for 1NO or 01 for 1NC). The top-mounted design allows for easy addition of auxiliary contact blocks, time delays, and mechanical interlocks.

• Rapid Heat Dissipation: The optimized arc-extinguishing chamber and high-quality flame-retardant housing ensure the unit remains cool even during high-frequency switching.

• Standard DIN Rail Mounting: Features a universal 35mm DIN rail clip and screw-mount holes for fast, secure installation in any standard electrical cabinet or air conditioning unit.

1. HVAC Systems: Controlling compressors and fan motors in commercial air conditioning and refrigeration units.

2. Motor Starting: Operating pumps, conveyors, and industrial mixers in manufacturing plants.

3. Lighting Control: Managing high-power outdoor lighting and stadium floodlights.

4. Automatic Transfer Switches (ATS): Used in pairs with mechanical interlocks for backup power switching.

• Proven Interchangeability: Our NC1 contactors share the exact mounting dimensions and electrical characteristics as major global brands, allowing for a "drop-in" replacement without re-wiring.

• Quiet Operation: Precision-ground electromagnetic cores reduce "humming" and vibration, making these contactors suitable for hospital and office building environments.

• Strict Quality Control: Each unit is tested for coil pull-in/drop-out voltage and contact resistance before leaving the factory.

• Bulk Export Support: We provide reinforced packaging and flexible logistics for international distributors and large-scale project tenders.

Q: What do the numbers "0910" or "2501" mean in the model name?

A: The first two digits (e.g., 09) represent the rated current in Amps. The third digit (1) represents the number of NO (Normally Open) auxiliary contacts, and the fourth digit (0) represents the number of NC (Normally Closed) auxiliary contacts.

Q: Can this contactor be used on 60Hz power systems?

A: Yes. The NC1 coils are designed to operate efficiently on both 50Hz and 60Hz AC frequencies.

Q: Do I need a separate relay for motor protection?

A: Yes. For motor applications, we recommend pairing the NC1 with an NR2 Thermal Overload Relay to provide protection against phase failure and overloads.
