Distribution Boxes / DC Distribution Box
DC Distribution Boxes for Battery Storage and DC Systems
A DC distribution box sits between the battery bank and the inverters, or feeds DC loads from a common DC bus. TPKELE builds the box to your drawing with DC breakers, DC surge protection and planned cable entry.

Frequently Asked Questions
Can you supply DC boxes above 125A?
Yes. TPKELE DC MCBs cover 1–125A. For higher currents, such as the 300A battery isolation in the Mongolia project, the box uses a project-specified DC MCCB.
Do you build to our own drawing?
Yes. Send the single-line diagram; TPKELE returns a layout and bill of materials for approval before production.
