ELECTRICAL INTERLOCKS
INDUSTRY STANDARDS
UL 508A Component Recognized; File No. E61997
CSA Certified; File No. 42186
APPLICATION
Provide positive internal safety lockout on electrical enclosures
while the equipment is energized. Use catalog numbers AEK115,
AEK230 and AEK460 are used with standard Hoffman door latching
mechanisms. When energized, these interlocks prevent the door
handle from being turned to open the door. Fit either clockwise or
counterclockwise handles in the following enclosures:
1. All two-door Type 4 and 12 enclosures
2. All Type 4X with 3-point latch enclosures
3. Free-standing Type 12 enclosures
4. All one-door Type 12 enclosures with latch kits installed
The interlocks will fit the following enclosures, but modifications
are required. Consult the factory for more information.
1. Two-door Type 12 enclosures for flange-mounted
disconnects
2. Heavy duty free-standing Type 12 enclosures for flange-
mounted disconnects
3. Modular Type 12 enclosures for flange-mounted
disconnects
4. Multi-door Type 12 enclosures
The interlocks will also fit most Hoffman custom enclosures
with door latching mechanisms similar to the mechanisms used
on the preceding enclosures. AC electrical interlocks will not
fit CONCEPT™ enclosures or Bulletin A25 and A26 enclosures.
Interlocks are not designed to be used in place of the standard door
or cover latch.
Catalog numbers AEK115NDH, AEK230NDH and AEK460NDH are
designed to be used on some Hoffman enclosures and boxes which
have exterior latching only. When energized, these interlocks will
prevent the enclosure door from being opened. They fit on the door
or cover of the following enclosures and maintain UL Type 4, 4X and
12 when properly installed per Hoffman instructions:
1. One-door Type 4 and 4X enclosures
2. Two-door Type 4 and 4X enclosures
3. One-door Type 12 enclosures
4. Larger sizes of CH, CHS, CHNF, CHNFSS and CHAL junction
boxes
5. Type 1 and large Type 1 enclosures
The interlocks also fit in most Hoffman custom enclosures and
boxes which have doors or covers hinged similar to doors or covers
on the preceding enclosures.
Installation
AEK115, AEK230 and AEK460 mount on the inside of the enclosure
door using the same screws which hold the door handle in place.
The strike plate attaches to the existing latch assembly.
