Howard Industries' Switch-Pad™ is an oil filled, pad-mounted device intended for fusing,
sectionalizing and tapping applications on medium voltage underground electrical
distribution systems. Switch-Pad™ can be provided in a number of different configurations
including one-, two-, or three-pole designs and is available with numerous switching and fusing options.
Housed in the same oil-filled enclosure used for single-phase pad-mounted transformers,
Switch-Pad™ will blend in well with other pad-mounted equipment in any underground residential
or commercial system.
