Double Side Opening Disconnect Switch

The DAL (Double Side Opening) switch consists of three columns of insulators, with the central column being rotatable to operate and support the blades, while the two lateral columns remain fixed.

The switch phases are mounted on a steel tube base, with cast aluminum and stainless steel components complementing its assembly to ensure maximum safety and robustness. The use of adjustable profiles between the three phases enhances stability, and its insulators are made of porcelain.

The support, base, and other metal parts are manufactured from hot-dip galvanized steel in compliance with NBR 6323.

It can be supplied according to customer requirements for installation on both concrete and metal structures.

The switch can be operated either manually or by motor, using a control panel equipped with multiple auxiliary contact blocks. Additionally, electrical, electromechanical, or mechanical interlocking devices can be supplied as needed.

Maurizio Three-Phase Switches are tested and approved in accordance with IEC 62271, NBR 7571, and ANSI C37.32-2002 standards.
