Chint NXBLE32-2PC25 is a disyuntor miniatura 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:
I. Parámetros principales
1. Especificaciones básicas
– **Rated Current**: 25A, applicable to circuits with a load current not exceeding 25A (such as air conditioners, electrodomésticos de cocina, etc.).
– **Pole Number**: 2PAG (two poles), which can cut off both the live wire and neutral wire simultaneously, providing more comprehensive safety protection.
– **Breaking Capacity**: 6el, capable of quickly cutting off fault currents up to 6000A in case of short circuits, complying with the standards of GB/T 16917.1 y CEI 61009-1.
2. Residual Current Protection Function
– **Residual Operating Current**: 50mamá (confirmed based on the model suffix “2PC25” and search results). When the residual current reaches 50mA, the circuit breaker trips within 0.1 artículos de segunda clase, effectively preventing electric shocks and electrical fires.
– **Tripping Characteristic**: Curva tipo C, suitable for general loads such as lighting and sockets (the tripping current is 5-10 veces la corriente nominal, es decir., 125-250A).
3. Parámetros eléctricos
– **Rated Voltage**: 230V (for 2P model), applicable to single-phase 220V circuits.
– **Frequency**: 50Hz, conforming to China’s power grid standards.
II. Design and Safety Features
1. Diseño Estructural
– **Compact Size**: With a width of approximately 36mm (2 módulos), it can be installed on a standard 35mm guide rail, ahorro de espacio en la caja de distribución.
– **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**: Más que 20,000 veces; **Electrical Life**: Más que 10,000 veces, featuring strong durability.
3. Instalación y mantenimiento
– **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 para cable vivo, N para cable neutro).
– **Removal Method**: The circuit breaker can be quickly removed through the “Lift” y “Tilt” operations on the side, facilitating maintenance or replacement.
III. Escenarios de aplicación
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, cortocircuito, and residual current risks.
2. Commercial Premises
Suitable for small and medium-sized power distribution systems in offices, stores, etc., to protect the safety of equipment such as computers and printers.
3. Controles Industriales
It provides basic circuit protection in small industrial equipment or distribution boxes.
IV. Precio y sugerencias de compra
1. Precio de mercado
Whatsapp: 0086-13811255435. The price per unit is approximately 24.53-45 RMB.
. Purchase Notes
– Confirm that the load current does not exceed 25A to avoid frequent tripping.
– If higher sensitivity (p.ej., 30mamá) se requiere, you can choose the version with the suffix “30mamá” (such as NXBLE32-2PC25 30mA).
– It is recommended to purchase from official channels or authorized distributors to ensure product quality and after-sales service.
V. Usage and Maintenance Tips
1. Pruebas periódicas
Press the test button monthly to observe whether it trips normally and ensure the residual current protection function is effective.
2. Fault Handling
después de tropezar, it is necessary to first eliminate line faults (such as short circuits, corriente residual), then press the reset button (blue button) before closing the breaker.
3. Requisitos ambientales
Avoid using it in environments with high temperature, humedad, 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, cortocircuito, and residual current protection for circuits, and is an ideal choice for residential and small-to-medium-sized power distribution systems. Antes de la instalación, be sure to refer to the product manual or consult a professional electrician to ensure correct model selection and wiring.
