AJB DCDB 2IN-1OUT 1000V – Fuse & SPD as SIBASS

The Array Junction Box (AJB) with DC Distribution Box (DCDB) is engineered to combine two PV string inputs into a single output while ensuring maximum safety and efficiency in 1000V DC solar photovoltaic systems.

This model is equipped with SIBASS fuse holders and fuses for reliable overcurrent protection, along with SIBASS Surge Protection Devices (SPD) to safeguard against lightning strikes and transient overvoltages. It provides robust protection and long-term reliability, making it suitable for commercial and utility-scale solar PV installations.

Key Features:

• Configuration: 2 Inputs – 1 Output

• Rated Voltage: 1000V DC

• Protection Devices:

  • Fuse (SIBASS): Protects each string from reverse current and overcurrent faults

  • SPD (SIBASS): Provides surge protection against lightning and grid disturbances

  • Optional DC MCB/Isolator for switching and short-circuit safety

• Enclosure: IP65/IP66 rated, UV-resistant polycarbonate or powder-coated metal enclosure

• Connectivity: Heavy-duty terminals with cable glands for secure, maintenance-friendly wiring

• Compliance: Designed as per IEC/IS standards for solar PV safety
