Chint NXBLE32-2PC25 is a miniature circuit breaker with residual current protection function, suitable for circuit protection in residential, commercial and industrial scenarios. The following is a detailed analysis of its core parameters and characteristics:
ฉัน. พารามิเตอร์หลัก
1. Basic Specifications
– **Rated Current**: 25ก, applicable to circuits with a load current not exceeding 25A (such as air conditioners, kitchen appliances, ฯลฯ).
– **Pole Number**: 2ป (two poles), which can cut off both the live wire and neutral wire simultaneously, providing more comprehensive safety protection.
– **Breaking Capacity**: 6ที่, capable of quickly cutting off fault currents up to 6000A in case of short circuits, complying with the standards of GB/T 16917.1 และไออีซี 61009-1.
2. Residual Current Protection Function
– **Residual Operating Current**: 50มิลลิแอมป์ (confirmed based on the model suffix “2PC25” and search results). When the residual current reaches 50mA, the circuit breaker trips within 0.1 วินาที, effectively preventing electric shocks and electrical fires.
– **Tripping Characteristic**: Type C curve, suitable for general loads such as lighting and sockets (the tripping current is 5-10 คูณด้วยกระแสไฟที่กำหนด, เช่น., 125-250ก).
3. Electrical Parameters
– **Rated Voltage**: 230วี (for 2P model), applicable to single-phase 220V circuits.
– **Frequency**: 50Hz, conforming to China’s power grid standards.
ครั้งที่สอง. Design and Safety Features
1. การออกแบบโครงสร้าง
– **Compact Size**: With a width of approximately 36mm (2 โมดูล), it can be installed on a standard 35mm guide rail, saving space in the distribution box.
– **Operation Indication**: A red mark shows “ON” when the breaker is closed, and a green mark shows “OFF” when it is open, making the status clear at a glance. There is a test button on the side; it is recommended to press it once a month to check if the residual current protection function is normal.
2. Certification and Reliability
– It has passed the CCC certification and meets China’s mandatory safety standards; some models support CE certification, making them suitable for the international market.
– **Mechanical Life**: More than 20,000 ครั้ง; **Electrical Life**: More than 10,000 ครั้ง, featuring strong durability.
3. การติดตั้งและบำรุงรักษา
– **Wiring Method**: Top-in and bottom-out, supporting 6-10mm² wire connection. Attention should be paid to the correct connection of the neutral wire and live wire (L for live wire, N for neutral wire).
– **Removal Method**: The circuit breaker can be quickly removed through the “Lift” และ “Tilt” operations on the side, facilitating maintenance or replacement.
III. สถานการณ์การใช้งาน
1. Residential Electricity Use
It serves as branch circuit protection, used in socket and lighting circuits in areas such as bedrooms, living rooms, and kitchens to prevent overload, ไฟฟ้าลัดวงจร, and residual current risks.
2. Commercial Premises
Suitable for small and medium-sized power distribution systems in offices, stores, ฯลฯ, to protect the safety of equipment such as computers and printers.
3. การควบคุมอุตสาหกรรม
It provides basic circuit protection in small industrial equipment or distribution boxes.
IV. Price and Purchase Suggestions
1. ราคาตลาด
วอทส์แอพพ์: 0086-13811255435. The price per unit is approximately 24.53-45 หยวน.
. หมายเหตุการซื้อ
– Confirm that the load current does not exceed 25A to avoid frequent tripping.
– If higher sensitivity (เช่น, 30มิลลิแอมป์) เป็นสิ่งจำเป็น, you can choose the version with the suffix “30มิลลิแอมป์” (such as NXBLE32-2PC25 30mA).
– It is recommended to purchase from official channels or authorized distributors to ensure product quality and after-sales service.
วี. Usage and Maintenance Tips
1. Regular Testing
Press the test button monthly to observe whether it trips normally and ensure the residual current protection function is effective.
2. การจัดการข้อผิดพลาด
หลังจากสะดุด, it is necessary to first eliminate line faults (such as short circuits, กระแสไฟตกค้าง), then press the reset button (blue button) before closing the breaker.
3. ข้อกำหนดด้านสิ่งแวดล้อม
Avoid using it in environments with high temperature, humidity, or heavy dust. It is recommended to install it in a distribution box to extend its service life.
With the above parameters and characteristics, Chint NXBLE32-2PC25 can provide reliable overload, ลัดวงจร, and residual current protection for circuits, and is an ideal choice for residential and small-to-medium-sized power distribution systems. ก่อนการติดตั้ง, be sure to refer to the product manual or consult a professional electrician to ensure correct model selection and wiring.
