ACDB + DCDB Combo Box — MCB SPD + MCB SPD (Havells)

Integrated IP65-rated AC/DC protection suite with dual-stage Type-2 40kA SPDs and C-Curve MCBs, delivering high-speed surge suppression and resettable overcurrent safety for solar PV systems.

Inquiry

A complete AC + DC protection suite in one IP65-rated enclosure, with resettable protection on both sides. Each side pairs a high-breaking-capacity C-Curve MCB with a Type-2 40kA surge arrester, giving dual-layered transient suppression and overcurrent safety. Because both the AC and DC sides use MCBs rather than fuses, a tripped circuit can be reset on site instead of replaced — saving a callout and a spare part. Built entirely with Havells components and made to sit outdoors through heat, dust, and monsoon. Supplied in bulk; custom configurations on request.
