The ACDB 50kW with NVR (Havells MCCB) is an AC Distribution Box designed to manage and protect the alternating current (AC) output from solar inverters in a solar power system. Below are the key details:

Key Features:

• Capacity: Designed for solar systems up to 50 kW.
• MCCB Brand: Equipped with a high-quality Havells MCCB for reliable overcurrent protection.
• Voltage Rating: Supports a maximum voltage of 415V AC, suitable for three-phase systems.
• NVR (No Volt Release): Ensures the system disconnects safely during power failures, providing enhanced safety and protection.
• Material: Typically constructed from durable materials like polycarbonate or mild steel, ensuring long-term reliability.
• Ingress Protection: Often rated IP54 or IP65, making it dust-tight and resistant to water ingress for outdoor applications.

Protection Features:

• MCCB (Molded Case Circuit Breaker): Protects against overloads and short circuits.
• NVR (No Volt Release): Automatically disconnects the system during grid failure or power loss.
• SPD (Surge Protection Device): Protects the system from voltage surges caused by lightning or grid fluctuations.

Specifications:

• Input/Output: 3-phase input/output connections.
• Enclosure Dimensions: Generally around 400mm x 300mm x 150mm (varies by manufacturer).
• Frequency: Operates at 50/60 Hz.
• Color: Typically gray or white.

Benefits:

• Enhanced Safety: Provides comprehensive protection for solar inverters and connected loads by preventing damage from electrical faults or surges.
• Easy Maintenance: Modular design allows for quick replacements of components like MCCBs and SPDs.
• Durable Design: Weatherproof enclosure ensures reliable operation in harsh outdoor conditions.
• Grid Compliance: Includes features like NVR to ensure compliance with grid safety standards.

Applications:

The ACDB 50kW with NVR is ideal for:

• Medium-sized commercial solar installations.
• Industrial setups requiring reliable AC power distribution and protection.
• Residential solar systems with three-phase connections.
