HVL/cb Vacuum Circuit Breaker Switchgear—5-15 kV, 1200 A

Square D™ brand metal-enclosed switchgear has become an industry standard for its superior system performance, low maintenance cost, easy system expansion, and reduced system expense.

Square D™ brand HVL/cb vacuum interrupter switchgear offers a small footprint, reduced capital and operational expenditures, longer maintenance cycles, and initial low cost offer for the market. With the incorporation of the Evolis vacuum circuit breaker, the switchgear is able to operate at up to 10,000 operations.

Standing at 24 in. wide, 90 in. inches high, and 65 in.deep, this equipment is NEMA 1 rated and adheres to the ANSI IEEE standard. Additional features include switchgear ratings up to 1200 A for the main bus, 15 kV for the system voltage, a 25 kA interrupting rating, and up to 95 kV BIL.

HVL/cb switchgear is designed for front-only or front or rear access, which allows the switchgear be placed against a wall without an NEC-governed rear aisle. The “Type 2b” arc resistant option has a plenum behind the low voltage compartment that does not require any additional height space to be added to the switchgear. Designed for top and bottom cable entry, the units can be equipped with either the over-toggle mechanism (OTM) or the stored-energy mechanism (SEM), making this switchgear ideal for most applications.
