The DCDB 4 IN 4 OUT – 3 MPPT (MCB + SPD) 1000V is an advanced Solar DC Distribution Box designed to provide reliable protection and safe isolation for 4 PV string inputs and 4 outputs connected to 3 MPPTs in high-voltage solar photovoltaic systems. It integrates DC MCB protection and DC Surge Protection Devices (SPD) to safeguard solar equipment against overcurrent, short circuits, and transient voltage surges caused by lightning or electrical disturbances.
The unit is equipped with 4 Nos. of 32A DC MCBs (LK/Havells) for string-level protection and 3 Nos. of DC SPDs (Havells) for MPPT-wise surge protection, ensuring enhanced safety and system reliability. The enclosure is made from a durable 400 × 400 × 150 mm ABS + PC material, providing excellent resistance against UV rays, dust, moisture, and harsh environmental conditions.
