HVL Metal-Enclosed Load Interrupter Switchgear — Full Range

The Square D HVL 5–38 kV Load Interrupter is the most popular ANSI-rated switchgear in its class in the country.

Both the switch and enclosure of medium voltage interrupter switchgear are industry standards in terms of design, production, and performance. The load interrupter switchgear must carry out a number of important operations in a unit substation, including protecting equipment and disconnecting faulty lines and transformers. HVL has been designed to offer exceptional protection for your distribution system.

HVL switchgear is available for various applications and configurations, including:

  • Individual service entrance bays
  • Multiple-bay lineups incorporating HVL load interrupters
  • Substation primaries

The Square D brand metal-enclosed switchgear has established itself as an industry standard for improved system performance, lower maintenance cost, easier system growth, and decreased system cost.

Fuselogic™

The ultimate in medium voltage fuse protection, FuseLogic uses Square D current-limiting fuses with mechanical sensors that operate without the need for additional energy with no auxiliary power requirements. Fuselogic functions may be combined to offer blown fuse indication contacts with mechanical lockout and anti-single phasing protection. Anti-single phasing requires the optional stored energy mechanism (SEM). HVL/ccTM and HVL switches are both available with FuseLogic.

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

Basic fused and unfused load interrupter switch configurations for stand-alone or transformer primaries are available through the HVL quick ship program. The Quick Ship option provides faster delivery, but with fewer custom options.

600 A individual HVL switches are available in free-standing indoor (NEMA 1) or outdoor (NEMA 3R) enclosures, each with a three-pole, 600 A capacity. The switches used in these enclosures are UL Recognized and are listed under Category WIQG2 in File E140591(M). These switches are available unfused or with provisions for DIN—style, Square D™ brand current-limiting fuses or for boric acid fuses. Additional switches, extra cable terminating lugs, and distribution class surge arresters are all available as optional accessories.

The door is locked with a switch operating handle and key interlocks are built in. For line and load connections, set screw type lugs are provided on #2 solid—600 kcmil copper or aluminum cables. A bolted enclosure with a viewing window, ground pad, and space heater (NEMA 3R only) are other standard features. The heater’s control power must come from an external source. Fuses are not furnished with this equipment. Refer to DIN/E Current-Limiting Fuses, Non-Disconnecting Type or Boric Acid Fuses for fuse information. Many of the switches listed in these tables are available from stock. The following tables provide details on switches and HVL Switches for Power-Dry II ™, Power-Cast II ™, and Uni-Cast II ™ Transformer Connections.

Provisions for Future Expansion

All “single” Digest switches have provisions for future expansion on either side. Order kits HVMB for top crossover copper 600 A bus and HVLC for line connections to the top bus.

HVL Switches for Power-Dry II ™, Power-Cast II ™,
and Uni-Cast II ™ Transformer Connections

For unit substation primary main switches, HVL switches can be configured for close coupling cable connections to listed dry type transformers. You can see these listed in the tables below with current-limiting or boric acid fuses. We have included both single and duplex switch mains. Transformers are listed on Medium Voltage Distribution Transformers and may not be suitable for close coupling. For transformer availability and specific configurations, contact Spike Electric or your representative.

Fuse Selection

Selecting the fuse is the customer’s responsibility and should be based on transformer and system characteristics. A standard rule of thumb for selecting fuses for transformer protection is to multiply the self-cooled full load current of the transformer (or the next higher fuse rating) by 1.33.

Moreover, maximum fuse size can be determined by comparing the fuse total clearing curve to the transformer damage curve. Contact Schneider Electric for transformer overload and short-circuit withstand capability. The minimum fuse size should carry the transformer magnetizing inrush current of 12 times full load amperes for 0.1 second.

Standard Features

  • Switches for transformer primaries are cable connected only.

  • Key interlocks must be ordered and coordinated by customer.

  • Standard color is ANSI 61 for standalone units; ANSI 49 for switches connecting to transformers.

  • If switches are purchased to coordinate with Square D™ brand transformers, composite drawings and shipment coordination will not be available.

  • Switches are not designed for any special dimensions for retrofit purposes. For dimensions other than shown, contact your nearest Schneider Electric sales office or your local Schneider Electric distributor.

Ordering Information

Select switch catalog number based on fused or unfused and enclosure type.

  1. Select catalog numbers for factory modifications from the table above.
  2. If fused, select fuse from DIN/E Current-Limiting Fuses, Non-Disconnecting Type (Extended Travel Blown Fuse Indicator) or Boric Acid Fuses.
  3. Price switch and fuses separately. Switches are furnished with provisions only for current-limiting fuse or boric acid fuse.

RECONDITIONED
Yes. We provide reconditioned fan control panels as well. We believe in delivering quality products and solutions that have reliability and longevity. Hence, our reconditioned fan control panels and other equipment are thoroughly inspected and will offer services that are as good as new equipment. Also, our reconditioned equipment is affordable, because while quality is high, cost needn’t be.

UPGRADING
Our large on hand inventory of contactors, circuit breakers, relays, PLC, and other control products we can help you upgrade the functionality of your control panel effectively.  Replacing the old with the newsiest technology doesn’t always mean you have to completely tear out your existing panel along with the wire that has already been pulled. We can retrofit and engineer a new back panel for you with all of your components pre wired. We will supply you with a full 3D CAD lay out, a BOM of suggested upgraded components, along with wiring schematics showing you exactly how the upgrade will look. We will work with your contractor in technical questions to help ensure the old is taken out and the new replaced properly.
