The DCDB 4 IN 4 OUT – 4 MPPT (MCB + SPD) 1000V is a high-performance Solar DC Distribution Box designed to provide safe protection and isolation for 4 PV string inputs and 4 outputs connected to 4 separate MPPTs in high-voltage solar photovoltaic systems. It combines DC MCB protection and DC Surge Protection Devices (SPD) to protect solar components from 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 individual string protection and 4 Nos. of DC SPDs (Havells) for dedicated MPPT-wise surge protection. The enclosure is manufactured using a durable 560 × 380 × 180 mm ABS + PC material, offering excellent resistance against UV rays, dust, moisture, and harsh outdoor environments.
