The AC Distribution Box (ACDB) 40A 3-Phase with NVR is designed for safe and efficient management of AC power in solar rooftop and industrial applications. It provides protection against overcurrent, short circuit, and surges while ensuring system reliability with a built-in No-Volt Release (NVR) feature.

This ACDB is suitable for integrating solar power plants with the main grid or backup systems, providing a safe connection point between the inverter and the AC loads.

Key Features:

• Rated Current: 40A, 3-Phase

• Input Voltage: 415V AC ±10%

• Output Phases: 3-Phase

• NVR (No-Volt Release): Ensures safety by disconnecting power automatically during voltage failure or drop, preventing damage to connected equipment.

• Compact & Durable Enclosure: IP65 powder-coated MS box for indoor/outdoor use.

• Standard Compliance: As per IEC/IS standards for safety and performance.

Components Included:

1. AC MCB (40A) – Protects against overload and short circuit.

2. AC SPD (Surge Protection Device, 3-Phase) – Safeguards the system from voltage surges due to lightning or grid faults.

3. 3-Phase Contactor (40A) with NVR – Provides controlled power switching and automatic disconnection during voltage failure.

4. Enclosure Size: 280mm x 280mm – Compact, weather-resistant design.
