General

Square D™ brand HVL/cc metal-enclosed load interrupter switchgear with a sealed switch enclosure contains the contact arcing from switch contacts (all interruption takes place within the sealed enclosure), a critical concern in gaseous environments – Class 1 Div 2 certified. The permanently sealed switch help prevent switch contamination, especially important in dusty environments, thus eliminating maintenance on main and ground switch contacts.

Its compact size is made up of modular units, making the HVL/cc easy to expand future extensions and connections to existing equipment and ideal for retrofit applications. With front access, only options available at system voltages below 17.5 kV can be positioned against walls, in small rooms, or in prefabricated buildings. The small footprint can result in considerable cost savings from the reduction of building or room sizes.

The HVL/cc switch can be equipped with either an over-toggle mechanism (OTM), which is standard, or an optional stored energy mechanism (SEM). Top or bottom cable entry enhances installation flexibility. Enclosures are free-standing and suitable for both indoor (NEMA 1) and outdoor (NEMA 3R) applications.
