ChintNXBLE63 – 2P/C40

ChintNXBLE63 – 2P/C40 is a 2 – palo (2P) miniature residual current circuit breaker. Its main parameters and functions are as follows:

Parametri fondamentali

Corrente nominale: 40UN (“Q40” indicates that the tripping characteristic is Type C and the rated current is 40A);

Numero di poli: 2P (cuts off both the live wire and the neutral wire simultaneously);

Protezione corrente residua: Tipo CA (detects ordinary AC leakage). The residual operating current is usually 30mA (an industry conventional value, and some models support options such as 50mA/75mA);

Capacità di interruzione: 6IL (can safely cut off circuits with a short – circuit current of not less than 6000A);

Tensione applicabile: 230V (for single – circuiti di fase);

Mechanical/Electrical Life: The mechanical life is 20,000 volte, e la vita elettrica lo è 10,000 volte.

Funzioni principali

1. Protezione corrente residua: When there is electric shock to the human body (current ≥ 30mA) or equipment leakage in the circuit, l'alimentazione viene rapidamente interrotta all'interno 0.1 second to prevent electric shock casualties;
2. Protezione da sovraccarico: If the circuit load is too large (current exceeds 40A), it will automatically disconnect to avoid overheating and fire of the circuit;
3. Corto – Protezione del circuito: When a short circuit occurs in the circuit (current increases sharply in an instant), the circuit is cut off immediately to protect electrical appliances and the circuit;
4. Funzione di isolamento: It can be used as a switch for infrequent on – off of the circuit under normal conditions.

Scenari applicativi

Elettricità domestica: For high – power socket circuits in kitchens, salotti, ecc. (come i condizionatori, scaldabagni elettrici), it replaces traditional air switches and adds residual current protection;

Piccolo – scale Commercial Places: For socket or lighting circuits in convenience stores and offices, meeting the electricity demand within 40A;

Decoration and Renovation: Upgrading the residual current protection of old circuits to meet the new national standard’s requirement that “socket circuits must be equipped with residual current protection”.

Installation and Use Precautions

– It should be selected according to the actual load of the circuit to avoid “a big horse pulling a small cart” O “a small horse pulling a big cart”;

– Premere il “pulsante di prova (T key)” once a month to verify whether the residual current protection function is normal;

– Durante l'installazione, the live wire (l) e il filo neutro (N) must be distinguished. If the wiring is reversed, the residual current protection function may fail.
