Heavy Duty Safety Switches

Product Description

Series F

The Square Dby Schneider Electric brand Heavy Duty Safety Switch is designed to be tough, reliable and provide exceptional performance in the most grueling conditions; from commercial and institutional to industrial and manufacturing facilities. F Series safety switches provide significantly higher levels of mechanical endurance than NEMA Type KS-1 or UL98 standards require. The design life of a F-Series switch is a minimum of three times the NEMA requirement.

An abundance of copper is used in the heaviest current carrying power paths of all Square D by Schneider Electric Heavy Duty Safety Switches. The more copper for current carrying paths, the lower the temperature rise. Managing temperatures inside the switch is the key to providing greater service life.

All heavy duty safety switches feature a quick-make, quick-break operating mechanism, a dual cover interlock and a color-coded indicator handle.

Applications

Heavy duty safety switches are designed for the following applications:

  • Commercial and industrial installations

  • Up to 600 Vac or 600 Vdc maximum

  • Up to 200,000 rms symmetrical amperes short circuit current

  • Series F handle, mechanism and lock plate are field replaceable

  • Side-opening, left hinged covers

  • Highly visible embossed ON-OFF marking / ON-OFF labels are used on NEMA Type 4X fiberglass reinforced polyester enclosures

  • Quick-make, quick-break, operating mechanism

  • Standard with plated aluminum lugs which accept both Cu and Al wires

  • Front removable mechanical lugs

  • Dual cover interlock prevents the cover from being opened when the switch is ON and prevents the switch from being turned ON when the cover is open

  • An interlock bypass is provided for access by authorized personnel

Fuse Pullers

 

Class J Fuse Provisions Alternate mounting holes make for easy conversion to Class J fuses

 

Tangential Knockouts

  • Factory installed fuse pullers are standard on 30–100 A, NEMA Type 4/4X/5 stainless steel, NEMA Type 4X fiberglass reinforced polyester and NEMA Type 12 or 12K switches; Available as a kit for field installation on 30–100 A, F Series switches, NEMA Type 1 and 3R switches

  • 30–600 A switches are shipped with standard Class H fuse spacing. These switches will accept Class R fuses also; A field-installed rejection kit is available, which when installed, rejects all but Class R fuses;

  • See page 32 for Class R Fuse Kits

  • Fuse load base(s) can be repositioned to accept Class J fuses on

  • 30–600 A, 600 V switches and 100–600 A, 240 V switches;

  • 600 A switches also require a mounting kit (catalog number H600J)

Receptacle Switches

Interlocked receptacle switches are furnished with a factory-installed, three-phase, four-wire, Appleton Powertite, Crouse-Hinds Style 2 Arktite or Hubbellock™ receptacle. The fourth wire is connected to the switch equipment grounding terminal and is not a solid neutral termination. Interlocking linkage between the receptacle and switch mechanism prevents insertion or removal of the plug while the switch is in the “ON’’ position or insertion of any plug other than specified. The interlocking mechanism also prevents the switch from being turned “ON” if a plug has not been fully inserted into the receptacle.

Appleton Powertite Receptacle

Sample Applications

Locking Position—Designations

Diagram Symbols

NOTE: Device locked open = switch in OFF (O) position. Deviced locked closed = switch in ON (I) position.
  1. To prevent two devices from being closed simultaneously:

    Sample Application

    Figure 1 shows two devices that are not to be closed at the same time. Using key interlocks shown, only one key is required to operate the system
    • Both devices are shown open, therefore, the key is free

    • To close any one device insert the key and turn that particular lock

    • The key is held in this lock until the device is locked open

    • The procedure described above is the same for two devices, neither of which is to be opened simultaneously

  2. To prevent the opening of switch A when circuit breaker B is closed:

    Sample Application


    Figure 2 shows switch A and circuit breaker B in the closed position.
    • Key A-1 is held in circuit breaker B interlock

    • Open the circuit breaker

    • Turn key A-1 in the L-O-R interlock on circuit breaker B to lock open; Key A-1 is now free

    • Insert key A-1 in the L-C-R interlock on switch A and turn to unlock

    • Open switch A. Key A-1 is now held; Reverse the sequence to restore service

  3. To prevent operation of switch A when circuit breaker B is closed. Permits re-closing of the circuit breaker for servicing when switch is locked open:

    Sample Application


    Switch A and circuit breaker B are in the closed position.

    • Key A-1 is held in the circuit beaker interlock

    • Open the circuit beaker

    • Turn key A-1 in the L-O-R interlock on circuit breaker B to lock open; Key A-1 is now free

    • Insert key A-1 in the L-O-C-R interlock on switch A and turn to unlock

    • Open switch A; Key A-1 is now held

    • Turn key A-1 in the L-O-C-R interlock on switch A to lock open; Key A-1 is now free

    • Return key A-1 to circuit breaker interlock and unlock for operating during servicing period

    • Reverse the sequence to restore service

  4. To prevent paralleling of lines A and B; two loads, fed from either source (Main-Tie-Main):

    Sample Application


    Circuit breaker A is closed to supply load M. Circuit breaker B is closed to supply load N. Tie-circuit breaker C is open. Keys A-1 and held in interlocks on both circuit breakers A and B. Tie-circuit breaker C cannot be closed unless either A or B is locked open.

    To transfer load N to circuit breaker A, proceed as follows:

    • Open circuit breaker B

    • Turn key A-1 in L-O-R interlock on circuit breaker B to lock open; Key A-1 is now free

    • Insert key A-1 in L-O-R interlock on tie-circuit breaker B and turn to unlock; Key A-1 is now held

    • Close tie-circuit breaker C

    • Reverse the sequence to restore service

    • Load M can be supplied through circuit breaker B in a similar manner
