The ASCO 920 is designed as a feeder disconnect switch for load capacities beyond the ASCO 917. ASCO 920 RC switches are available for separate mounting in NEMA type enclosures or direct mounting within lighting panelboards for total or split-bus applications.

It is available from 30 through 225 amperes per pole with 2 or 3 poles and service voltages through 600 volts AC. The ASCO 920 is listed under UL 508 for ballast lighting, tungsten, general use and resistive loads. It also meets the withstand current rating requirements of UL 67 for panelboard applications.

The ASCO 920 is easy to install and features all-position mounting, no derating for high inrush loads and a reliable single-solenoid operator. ASCO 920 RC switches can be used with energy management systems which automatically control lighting and power circuits through control devices such as photoelectric cells, microprocessors, timers and occupancy sensors.
