NOTE: 30-200A. Type 3R Switches have
removable hub plates on rainsheds. 400A and
larger Type 3R Switches have no provisions
for mounting hubs. Drill or punch hole in the
field to accommodate hub size desired.
➀ Hubs suitable for 3R Switches.
➁ Neutral Barrier kits are required on 30-100A switch only and only with 1-Phase, 3W or 3-Phase and 4W loads.
Compression lugs mounting kits are required on 400-1200A switches only.
➂ Provides mounting for a single line or load lug.
➃ Provides mounting for two compression lugs per phase on line or load one per pole required.
➄ Line lugs have wire-bending space and are UL approved for #14-6 conductors.
➅ Max. wire size for height reduced switches is 500 Kcmil (Cu/Al).
➆ All but 60A GD & Compact HD NF switches are also UL approved for #2 Cu/Al conductors.
➇ All 200A Heavy Duty Switches have a wire range & wire bending space for one # 6-300 Kcmil (Cu/Al).
Compression Lug
Neutral Barrier Kit
All Heavy Duty Switches are field con-
vertible for crimp type lugs. When
compression lugs are required for 30-
100A switches, a neutral barrier kit is
required for 1-Phase, 3W or 3-Phase,
4W applications. When compression
lugs are required on 400-1200A
switches, lug mounting kits are
required.

Kirk-Key Interlocks
Kirk-Key Interlocks are factory installed
only on Type VII Heavy Duty and Double
Throw Safety Switches.
Interlocks are used to prevent the
authorized operator from making an
unauthorized operation. The interlock
system is a simple method of applying
key interlocks to safety switches so as to
require operation in a predetermined
sequence.
Before consulting the factory, the
following information is required:
• User name and address
• Key number from lock assemblies
on any existing locks to be inter-
locked with
• Complete locking scheme
Consult factory for delivery.
