Contactor Chint NC1-1201 is a 3-pole AC contactor specifically designed for industrial automation. It is suitable for frequent control of motors or other inductive loads.
1. Parametrii de bază
– Curent nominal: 12O (under AC-3 duty category, it can control a 5.5kW motor at 380V).
– Control Voltage: Supports multiple specifications such as 220VAC and 48VAC, with a coil frequency of 50/60Hz.
– Configurare contact: 3 deschis în mod normal (NU) main contacts + 1 în mod normal închis (NC) auxiliary contact. The auxiliary contact has a rated current of 10A and can be used for signal feedback or interlock control.
– Metoda de montare: Suportă montare pe șină DIN standard de 35 mm sau fixare cu șuruburi. The inclination of the mounting surface shall not exceed ±5°, making it suitable for compact distribution cabinets.
2. Certificari si standarde
– Domestic Certifications: Certified by CCC (China Compulsory Certification) and compliant with the GB14048.4 standard.
– International Certifications: Some models have obtained international certifications such as CE, UL, and VDE, making them applicable to global markets.
3. Performance Features
– High Reliability: Silver alloy contact material enhances electrical conductivity and corrosion resistance. The mechanical lifespan reaches 10 milioane de operațiuni, and the electrical lifespan under AC-3 is 1 milioane de operațiuni.
– Wide Voltage Adaptability: The coil pull-in voltage range is 85%-110% a tensiunii nominale, and the release voltage range is 20%-75% a tensiunii nominale, adapting to scenarios with large voltage fluctuations.
– Modular Expansion: Can be equipped with F4 auxiliary contact sets (până la 4 sets), F5 air time delay modules, or thermal relays to achieve functions such as time delay control and overload protection.
4. Scenarii de aplicare
– Controlul motorului: Commonly used for start-stop and forward-reverse control of three-phase asynchronous motors. When combined with a thermal relay, it can form an electromagnetic starter.
– Automatizare industrială: Serves as an executive component in PLC control systems to realize remote control of equipment and automated processes.
– Air Conditioning and Refrigeration Equipment: Some models (de ex., NC1-1201 220V for air conditioning) are suitable for controlling compressors and fans in HVAC systems.
5. Model Selection and Replacement
– Modele alternative:
– Same Brand: NC1-1210 (with 1NO + 1NC auxiliary contacts), NC1-1204 (4-pole configuration).
– International Brands: Schneider LC1D1201, ABB AF12-30-01. These models have compatible parameters and similar mounting dimensions.
– Precauții:
– Select the rated current according to the load type (AC-3/AC-4). For AC-4 loads (de ex., welding machines), derating is required during use.
– Ensure the control voltage matches the actual circuit to avoid coil burnout.
6. Price and Purchase
– Market Reference Price: The 220VAC model is approximately 26.89 RMB pe unitate (non-air conditioning dedicated), and the 48VAC model is approximately 71.51 RMB pe unitate (DC coil). Prices vary by channel and order quantity.
– Canale de achiziție: Available via Chint WhatsApp: 0086-13811255435. It is recommended to purchase through authorized distributors to ensure genuine products.
7. Instalare și întreținere
– Wiring Specificaions: For the main circuit, 2.5mm² flexible wires or 4mm² rigid wires are recommended. The auxiliary contacts support 1mm² wires, and the tightening torque is 0.8-1.2N·m.
– Recomandări de întreținere: Regularly clean the oxide layer on the contact surface, check the coil temperature rise (not exceeding 60K), and ensure the mechanical interlock mechanism operates flexibly.
