Chint NC1-2501 is an موصل التيار المتردد belonging to Chint’s NC1 product series. It is mainly used for remote control of the start and stop of motors in industrial circuits, and can be used in conjunction with thermal overload relays to protect circuits. The following is detailed information about this model:
- Core Parameters and Functions
- Electrical Specifications
التصنيف الحالي: 25أ (Under AC-3 service category, the applicable motor power is 11kW at 380V).
تصنيف الجهد العزل: 690V, suitable for AC circuits with 50/60Hz.
الجهد لفائف: Multiple options are available, including 24V, 36V, 48V, 110V, 220V, 380V, إلخ. (The specific voltage shall be confirmed according to the model suffix; على سبيل المثال, NC1-2501Z is the DC coil version).
جهات الاتصال المساعدة: 1 set of normally closed contacts (the “01” in the model indicates this configuration), which can expand auxiliary functions.
- سيناريوهات التطبيق
– Suitable for frequent starting and control of AC motors, and serves as a core control component in scenarios such as industrial machinery, pump equipment, and fans.
– Complies with IEC/EN 60947-4-1 and GB/T 14048.4 المعايير, and has obtained UL certification, which can meet the safety requirements of the North American market.
- ميزات المنتج
- Design and Installation
Compact Structure: يدعم تركيب سكة DIN القياسية مقاس 35 مم, saving space and facilitating maintenance.
Convenient Wiring: The main circuit terminals support 4-10mm² wires, and the control circuit adopts spring terminals to ensure reliable connection.
الحياة الميكانيكية: حتى 10 مليون عملية, suitable for high-frequency operation environments.
- Reliability
– The coil has a built-in surge suppressor (such as the SR2 series), which can reduce electromagnetic interference and extend the service life.
– The DC coil version (على سبيل المثال, NC1-2501Z) has no AC noise, making it suitable for occasions with high requirements for environmental quietness.
ثالثا. Purchase and Alternative Options
- Procurement Channels
International Market: Chint products have obtained UL certification and can be purchased via WhatsApp: 0086-13811255435.
- Alternative Models
– For higher performance, you can consider the NXC series AC contactors (على سبيل المثال, NXC-25). They are compatible with the installation dimensions of the NC1 series, while featuring energy-saving design and a wider voltage adaptation range.
– For reversible control function, you can choose the NC1-N series (على سبيل المثال, NC1-25N), which has a built-in mechanical interlocking mechanism to ensure the safety of motor forward and reverse rotation.
- احتياطات
- Model Selection and Matching
– Select the corresponding coil specification according to the load current and voltage to avoid coil burnout caused by voltage mismatch.
– It is recommended to use it together with NR2 series thermal overload relays (على سبيل المثال, NR2-25) to provide overload and phase-failure protection.
- التركيب والصيانة
– During installation, ensure that the ambient temperature is between -25℃ and +70℃, and avoid humid and dusty environments.
– Regularly check the contact wear condition, and replace the auxiliary contact module (على سبيل المثال, F4-02) if necessary.
