Chint NXBLE32-2PC25 小型サーキットブレーカー

Chint NXBLE32-2PC25 is a ミニチュアサーキットブレーカー with residual current protection function, suitable for circuit protection in residential, 商業および産業のシナリオ. The following is a detailed analysis of its core parameters and characteristics:

私. コアパラメータ

1. 基本仕様

– **Rated Current**: 25あ, applicable to circuits with a load current not exceeding 25A (エアコンなどの, キッチン家電, 等).

– **Pole Number**: 2P (2つの極), which can cut off both the live wire and neutral wire simultaneously, providing more comprehensive safety protection.

– **Breaking Capacity**: 6の, capable of quickly cutting off fault currents up to 6000A in case of short circuits, complying with the standards of GB/T 16917.1 およびIEC 61009-1.

2. 残留電流保護機能

– **Residual Operating Current**: 50ミリアンペア (confirmed based on the model suffix “2PC25” and search results). When the residual current reaches 50mA, the circuit breaker trips within 0.1 秒, effectively preventing electric shocks and electrical fires.

– **Tripping Characteristic**: タイプCカーブ, suitable for general loads such as lighting and sockets (the tripping current is 5-10 定格電流の倍, つまり, 125-250あ).

3. 電気的パラメータ

– **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. 構造設計

– **Compact Size**: With a width of approximately 36mm (2 モジュール), it can be installed on a standard 35mm guide rail, 配電ボックス内のスペースを節約.

– **Operation Indication**: A red mark shows “の上” when the breaker is closed, and a green mark shows “オフ” 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 回; **Electrical Life**: More than 10,000 回, 強い耐久性を特徴とする.

3. 設置とメンテナンス

– **Wiring Method**: トップインとボトムアウト, 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：中性線).

– **Removal Method**: The circuit breaker can be quickly removed through the “Lift” そして “Tilt” operations on the side, facilitating maintenance or replacement.

Ⅲ. アプリケーションシナリオ

1. Residential Electricity Use

It serves as branch circuit protection, used in socket and lighting circuits in areas such as bedrooms, リビングルーム, and kitchens to prevent overload, 短絡, and residual current risks.

2. Commercial Premises

Suitable for small and medium-sized power distribution systems in offices, stores, 等, to protect the safety of equipment such as computers and printers.

3. 産業用制御

It provides basic circuit protection in small industrial equipment or distribution boxes.

Ⅳ. 価格と購入の提案

1. 市場価格

ワッツアップ: 0086-13811255435. 1個あたりの価格はおよそ 24.53-45 人民元.

. Purchase Notes

– Confirm that the load current does not exceed 25A to avoid frequent tripping.

– If higher sensitivity (例えば, 30ミリアンペア) が必要です, you can choose the version with the suffix “30ミリアンペア” (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. 定期テスト

Press the test button monthly to observe whether it trips normally and ensure the residual current protection function is effective.

2. 障害処理

つまずいた後, it is necessary to first eliminate line faults (such as short circuits, 残留電流), then press the reset button (blue button) before closing the breaker.

3. 環境要件

Avoid using it in environments with high temperature, 湿度, 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, 短絡, and residual current protection for circuits, and is an ideal choice for residential and small-to-medium-sized power distribution systems. 設置前, be sure to refer to the product manual or consult a professional electrician to ensure correct model selection and wiring.
