LongArm Model ABL-2

The ABL2 remotely operates the ON/OFF handle on low voltage Allen-Bradley Centerline motor control center (MCC) cabinets. This remote switch operatort is of robust design with simplicity in mind as there is no prepositioning of the actuator arms for attachment. The ABL2 has built-in safety features protect the worker from inadvertent operation in all stages of use.

The ABL2 is magnetically attached to the Centerline MCC in seconds. The ABL2 actuator operates the ON/OFF handle with a swift and smooth motion. In addition, the ABL2 actuator and controller may be stored on the MCC for quick and convenient access.

The ABL2 is offered in two basic models – a wireless version (ABL2-W) and a cabled version (ABL2-C). The advantage of the wireless version is that there are no cables to deal with which makes it more convenient to use. The cabled version is offered because some customers prefer cable operated equipment.

Devices are also available for low voltage Allen-Bradley Centerline 2100 MCC buckets with small handles and for the medium voltage Allen-Bradley Centerline MCC.

The standard offering includes:

  • LongArm ABL3 Actuator
  • Hand-held wireless controller (with 50’ range)
  • Custom battery pack featuring Energizer Ultimate Lithium battery cells (tested to over 2000 operations before requiring replacement.)


  • The cabled (ABL3-C) version may be ordered with a 30’ or 50’ control cable
  • An alkaline battery pack may replace the Lithium battery pack in the event next day air shipping is required. (Expedited shipping options may be limited for units with Li batteries. An Alkaline battery pack is also available for expedited shipping requirements.)
