Product Overview

The MD_max hybrid AC low-voltage switchgear is a new-generation low-voltage switchgear developed by ABB and has passed type tests.

The drawer’s movable components can be positioned and matched with three types of indicators: sound, light, and text.

The frame uses a double-folded edge technology with aluminum-zinc coated steel sheets, offering high strength.

Drawer-type structure, capable of accommodating 36 circuits.

The intelligent drawer can achieve a three-position switching without compromising the level of protection.
