Asco 300 Manual Options

Asco offers two optional accessories for their Asco 300 manual transfer switches.

Accessory 170 User Interface/Annunciation is factory-installed and must be ordered with the transfer switch. It offers LED indicators and Form C contacts for transfer switch position and source availability. Can be configured with or without phase rotation monitoring, a maintained engine start switch, and an IO module for building management system integration.

Strip Heaters can be factory-installed or ordered later as a Field Kit.
