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.

600 A “Single” HVL/cc Switch with PROVISIONS ONLY for Square D™ brand Current-Limiting, Non-Disconnect Type Fuses for Cable Connection to Power-Dry™, Power-Cast™, and Uni-Cast™ Transformers

(FLC = 300 A MAXIMUM)
RH—Transformer on right, LH—Transformer on Left
Application A = Top Entry (Incoming Cables)
Application B = Bottom Entry (Incoming Cables)

• 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.

600 A “Duplex” HVL/cc Switch with PROVISIONS ONLY for Square D™ brand Current-Limiting, Non-Disconnect Type Fuses for Cable Connection to Power-Dry, Power-Cast, and Uni-Cast Transformers

• FLC = 300 A maximum

• RH—Transformer on right

• LH—Transformer on left includes mechanical interlock to prevent paralleling of sources

• Application A = top entry (incoming cables)

• Application B = bottom entry (incoming cables)

1. Select switch catalog number based on fused or unfused and cable entry locations (top or bottom) from Unfused Switch Selection, or Fused Switch Selection.

2. Select incoming line auxiliary bay from Bays for Bottom Entry/Exit Cables, or Bays for Top Entry/Exit Cables, if required.

3. Select main bus from Bus Kits, if required.

4. Select catalog numbers for factory modifications from Factory Modifications, if required.

5. If fused, select DIN/E fuses from Fuse Selection.

Fuselogic is a protection system that provides the ultimate in medium voltage equipment protection. This patented system utilizes the CS-3 Type striker type current-limiting fuses with mechanical sensors that function without any auxiliary power requirements. Several configurations of Fuselogic functions can be combined to provide simple blown fuse indication during operation contacts or closing of the switch with mechanical lockout to help prevent anti-single phasing protection. Anti-single phasing requires the optional stored energy mechanism (SEM). Fuselogic is available on both HVL/cc™ and HVL switches.

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. (See Factory Modifications.)

The rule of thumb method for selecting fuses for transformer protection is 1.33 times the self-cooled full load current of the transformer or the next higher fuse rating. Selection of the fuse is the customer’s responsibility and should be based on transformer and system characteristics.

• Maximum Fuse Size:
  Maximum fuse size should 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.

• Minimum Fuse Size:
  Minimum fuse size shall carry the transformer magnetizing inrush current of 12 times full load amperes for 0.1 second.

• 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.

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

2. Select catalog numbers for factory modifications from the table above.

3. If fused, select fuse from DIN/E Current-Limiting Fuses, Non-Disconnecting Type (Extended Travel Blown Fuse Indicator) or Boric Acid Fuses.

4. Price switch and fuses separately. Switches are furnished with provisions only for current-limiting fuse or boric acid fuse.
