HVL/cc Metal-Enclosed Load Interrupter Switchgear—Full Range

Square D™ brand HVL/cc metal-enclosed load interrupter switchgear provides switching, metering, and interrupting capabilities for medium voltage electrical power distribution systems and is designed and tested per applicable ANSI/IEEE and NEMA standards.

Made up of modular units, the HVL/cc is easy to expand. Two main bus positions allow future extensions and connections to existing equipment.

HVL/cc switchgear is available in either single or multiple bay units. The design is compact, with front-only accessibility.

The HVL/cc switch can be equipped with either an over-toggle mechanism (OTM), which is standard, or an optional stored energy mechanism (SEM). An option with both mechanisms is the Fuselogic™ system. The Fuselogic system offers fuse tripping (with SEM) to provide protection against single phasing loads when a fuse has blown.

The HVL/cc enclosure is designed for front access only and can be positioned against walls, in small rooms or in pre-fabricated buildings. The small footprint can result in considerable cost savings from the reduction of building or room sizes.

Fuselogic™

Fuselogic is a protection system that provides the ultimate in medium voltage fuse protection. This patented system utilizes Square D brand current-limiting fuses with mechanical sensors that function without any auxiliary power requirements. Several combinations of Fuselogic functions can be combined to provide simple blown fuse indication contacts with mechanical lockout to anti-single phasing protection. Anti-single phasing requires the optional stored energy mechanism. Fuselogic is available on both HVL/cc and HVL switches.

HVL/cc Switchgear Quick Ship Program—5–15 kV, 600 A

The HVL/cc quick ship program provides basic fused and unfused load interrupter switch configurations for standalone or transformer primary applications. The Quick Ship program offers faster delivery, but with fewer options.

Three-pole, 600 A individual HVL/cc switches are available in free-standing indoor (NEMA 1) enclosures. These switches are available unfused or with provisions for Square D brand current-limiting DIN/E fuses. Factory optional accessories include auxiliary bays, main bus, auxiliary switches, and distribution class surge arresters. The fuse access panel is mechanically interlocked with the switch mechanism. Key interlocks are not an available option with Digest-listed HVL/cc switches. (1) Set screw type lugs for (2) #2–350 kcmil copper or aluminum cables are provided for line and load connections. Fuses are not furnished with this equipment. For fuse information, refer to General Purpose E-Rated Current-Limiting Fuses:Type DIN/E for HVL/cc Switches.

Provisions for Future Expansion

  • All “single” HVL/cc switches have provisions for future expansion on either side

  • Order main bus kits for copper 600 A bus

600 A Single Switch Unfused

  • Manual over-toggle mechanism, no grounding switch

  • Includes (1) set screw for (2) #2–350 kcmil Cu or Al conductors per phase

  • Application A = Top entry (incoming—cable or main bus), bottom exit (load—cable or main bus)

  • Application B = Bottom entry (incoming—cable or main bus), top exit (load—cable or main bus)

note

Switches with transformer connections are painted ANSI 49. Standalone switches are painted ANSI 61. Transformer connections in HVL/cc switches are based on standard Square D™ brand transformer connections. If these switches are used to connect to other manufacturers' transformers, then connections must match standard Square D™ brand transformer connections. (Cable connections are furnished with the transformer.)

General Purpose E-Rated Current-Limiting Fuses: Type DIN/E for HVL/cc Switches

  • Integrated rating for 600 A HVL/cc switches with Square D™ brand DIN/E fuses listed below is 65 kA rms symmetrical amperes.

  • Current-limiting fuses increase the integrated short-circuit current rating because of their energy-limiting capabilities.

  • To increase the short-circuit current rating of the entire lineup of switchgear, current-limiting fuses must be used in the entrance sections.
