Product Core Parameters

1. Basic Parameters

定格電流: 40あ, suitable for medium-load circuits (such as air conditioners, water heaters, 等) in household or small commercial places.

極数: 2P (double pole), which can disconnect the live wire and neutral wire simultaneously to provide more comprehensive circuit protection.

Leakage Trip Current: 30ミリアンペア, in compliance with GB/T 16917.1 and IEC 61009-1 standards, which can quickly respond to leakage faults and protect personal safety.

遮断容量: 6の, which can effectively cut off short-circuit current and ensure circuit safety.

Tripping Characteristic: タイプC (suitable for lighting and mixed loads), capable of withstanding short-term impact currents.

2. Certifications and Standards

– Certified by China CCC (Certificate No.: 2024010307667898), meeting domestic electrical safety requirements.

– Compliant with the international standard IEC 61009-1, applicable to most markets worldwide.

3. Physical Properties

寸法: Approximately 94.5×72×78mm (referencing the NB6LE-63 of the same series), supporting TH35-7.5mm rail installation to save distribution box space.

Material: Environmentally friendly flame-retardant material with strong aging resistance and long service life.

アプリケーションシナリオ

1. Household Electricity

– As a protection switch for main inlets or branch circuits, it can prevent safety accidents caused by overload, 短絡, そして漏れ, especially suitable for high-power equipment such as air conditioners and electric water heaters.

– Supports (side-by-side installation) of multiple units, with a derating factor of 0.76In (when exceeding 9 単位), which needs to be adjusted according to actual loads.

2. New Energy Charging Piles

– Specifically designed for new energy charging piles, meeting the leakage protection requirements in high-current (40あ) scenarios, suitable for household or small commercial charging piles.

– Adopts Type A leakage protection, which can detect AC and pulsating DC leakage, with broader compatibility.

3. Industrial and Commercial Use

– Suitable for low-voltage distribution systems in factories, shops, 等, protecting motors, lighting equipment, 等, from damage caused by fault currents.

– Can be used in conjunction with other electrical components (such as contactors, リレー) to build a complete distribution protection solution.

Purchase and Usage Suggestions

1. Price and Packaging

– The unit price in the Chinese market is approximately 37-137 人民元, specifically depending on packaging specifications (single unit or boxed). 例えば, the single-unit quotation on Alibaba is 37 人民元, and a box (3 units/box) on Taobao is approximately 112 人民元.

– For bulk purchases (のような 54 units/case), more favorable prices can be obtained by contacting Whatsapp 0086-13811255435.

2. Purchase Channels

Domestic: Available on e-commerce platforms such as Suning.com, JD.com, Taobao, and Alibaba, with some merchants offering free shipping.

International: Purchasing through importers or international e-commerce platforms (such as Alibaba.com) is required. Note the certification compatibility and import duties (the tariff for Chinese electronic products exported to the U.S. is approximately 15%).

3. 設置とメンテナンス

– 設置前, confirm the circuit voltage (230V/400V), frequency (50Hz), and wire specifications (1-10mm²) to ensure compatibility.

– Regularly check the leakage protection function (例えば, press the test button monthly) to ensure it works normally.

– For model replacement, consider the NXBLE-63 2P C32A or NXBLE-63 2P C50A of the same series, specifically selected according to load requirements.

予防

1. International Usage Compatibility

– This product is mainly oriented to the Chinese market. For export to regions such as the U.S., confirm compliance with local standards (such as UL certification). Current search results do not mention UL certification, so it is recommended to consult suppliers or professional institutions.

– The U.S. voltage is 120V/240V, so confirm whether the product supports this voltage range (the NXBLE-63 series has a rated voltage of 230V/400V, possibly requiring step-down use).

2. Alternative Models and Discontinuation Information

– The CHINT official website still lists the NXBLE-63 series products without mentioning discontinuation. For alternative models, consider NXBLE-63E (special for charging piles) or NXBLE-125 (higher current rating).

3. Import Process

– Importing from China to the U.S. requires customs declaration, providing commercial invoices, packing lists, and other documents, and paying duties and possible value-added taxes. It is recommended to use a freight forwarder or customs broker to assist with customs clearance to save time.

まとめ

CHINT NXBLE63-2P40A is a cost-effective leakage protection circuit breaker suitable for household, charging pile, and small-to-medium commercial scenarios. Its core advantages include rapid leakage response, high short-circuit breaking capacity, and broad compatibility. Domestic users can purchase it conveniently through mainstream e-commerce platforms, while international users should pay attention to certifications and import procedures.
