Provides positive internal safety lockout on electrical enclosures

while the equipment is energized. 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. The interlock fits 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-stand Type 12 enclosures

4. All single-door Type 12 enclosures with latch kits installed

The above interlocks will fit the following enclosures, but

modifications are required. Consult the factory for more

information.

2. Heavy Duty Free-Stand Enclosures for Flange-Mounted

Disconnects, Type 12

The interlocks will also fit most Hoffman custom enclosures with

door latching mechanisms similar to the mechanisms used on the

preceding enclosures.

Non-NDH style 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:

1. One-door Type 4 and 4X enclosures

2. Two-door Type 4 and 4X enclosures

3. One-door Type 12 enclosures
