Interruttore differenziale CHINT NBHLE-40Y-1PC32

CHINT NBHLE-40Y-1PC32 is a 1P+N two-pole interruttore differenziale (RCD) specially designed for household and small-to-medium engineering applications. Integra il sovraccarico, cortocircuito, e funzioni di protezione dalle perdite, suitable for AC 50Hz/60Hz circuits with a rated voltage of 230V. Below is its core information and application guidelines:

1. Parametri tecnici fondamentali
2. Corrente nominale e caratteristiche di intervento

Corrente nominale: 32UN, adatto per carichi convenzionali come l'illuminazione, prese, and small air conditioners, supporting up to approximately 7kW single-phase devices (per esempio., instantaneous water heaters).

Default Type C trip characteristic (instantaneous trip at 5-10 volte la corrente nominale), ideal for resistive loads (per esempio., lampade, riscaldatori elettrici); for inductive loads like motors, Tipo D (instantaneous trip at 10-14 volte) is available.

2. Leakage Protection and Breaking Capacity

30mA leakage action current, rapidly cutting off faulty circuits within 0.1 secondi, conforme alla CEI 61009-1 e GB/T 16917.1 standards to prevent electric shock and fire risks.

Potere di interruzione: 6IL, capable of handling common household short-circuit currents (typically 2-4kA) to ensure safe power disconnection.

3. Electrical Performance and Certifications

– Tensione nominale: 230V, operating temperature range: -5°C fino a +70°C, IP20 protection grade, resistant to moisture and dust.

– Certified by CCC and compliant with CE standards, garantendo una qualità affidabile.

1. Scenari applicativi tipici
2. Household Power Distribution Systems

Branch Circuit Protection: Socket circuits in humid areas like kitchens and bathrooms to prevent safety accidents from leakage. Per esempio, scaldabagni elettrici (3-8kW) can directly use a 32A circuit breaker with 30mA leakage protection for dual-layer safety.

Whole-House Leakage Protection: If the distribution box lacks a main RCCB, NBHLE-40Y-1PC32 can serve as the main switch to monitor leakage across all circuits.

2. Commercial and Light Industrial Use

Small Office Equipment: Centralized power supply circuits for printers, proiettori, distributori d'acqua, ecc., to avoid overload and leakage risks.

Store Lighting Systems: LED strips and display cabinet circuits in clothing stores, cafes, ecc., providing stable protection.

3. New Energy Equipment Adaptation

AC Charging Pile Protection: Una pila di ricarica da 7kW (32UN) can directly use this circuit breaker as the main switch, paired with NXB series circuit breakers for hierarchical control.

PV Inverter Branch: Protection for the AC side of small household PV systems to prevent damage from backflow current.

III. Raccomandazioni per l'installazione e la selezione

1. Specifiche di installazione

Montaggio su guida: Compatible with TH35-7.5mm standard rails, wiring terminals support 2.5-10mm² conductors, and vertical installation is required for optimal heat dissipation.

Requisiti ambientali: Evitare l'installazione ad alta temperatura (>70°C), high-humidity, or flammable environments; distribution boxes must have reserved heat dissipation space (≥30 cm dal muro).

2. Logica di selezione

Carica corrispondenza: Equipment total power (W) ÷ tensione (230V) = corrente (UN). La corrente nominale dell'interruttore dovrebbe essere ≥ 1,2 volte il valore calcolato. Per esempio, a 6kW load corresponds to 26.1A, making a 32A circuit breaker compliant.

Leakage Protection Hierarchy: If the main switch already has an RCCB, use ordinary circuit breakers (per esempio., NXB63-2P/32A) for branches; se non, prioritize NBHLE series for whole-house protection.

3. Espansione accessoria

Funzioni ausiliarie: Can be paired with AX-X1 auxiliary contacts (indicate on/off status), AL-X1 alarm contacts (trigger signals during faults), or shunt trip coils (remote tripping control).

Compatibilità del sistema: Compatible with NXB series circuit breakers, rail sockets, and surge protectors (per esempio., NXU) to build modular power distribution systems.

1. Maintenance and Safety Tips
2. Ispezioni regolari

Monthly Testing: Press the test button (TEST) to verify the leakage protection function. Replace immediately if it fails to trip.

Annual Check: Use an infrared thermometer to detect contact temperatures (≤60°C) e prevenire un aumento della resistenza di contatto dovuta all'ossidazione.

2. Risoluzione dei problemi

Scatti frequenti: If overload or short circuit is ruled out, aging insulation may be the cause, requiring professional electrical inspection.

Leakage Indicator Protrusion: Indicates a past leakage fault; identify and fix the cause before resetting.

1. Prezzi e canali di acquisto

Prezzo di mercato: Reference price per unit is approximately 150-200 Città di New York (subject to local dealers).

Purchase Advice: Procure through CHINT’s official channels (per esempio., Tmall flagship store, authorized dealers) to ensure product quality and after-sales service.

1. Typical Configuration Schemes

Con elevata affidabilità e adattabilità flessibile, CHINT NBHLE-40Y-1PC32 is the ideal choice for leakage protection in household and small-to-medium engineering projects. Users can select trip characteristics based on load types and strictly follow installation guidelines to ensure electrical safety.
