ASCO SERIES 185 Power Transfer Switches
For Residential or Light Commercial Use

ASCO SERIES 185 Generator Transfer Switches reliably connect power from a backup generator to your home or business whenever outages occur. When utility power has been restored, this line of power transfer switches will automatically transfer your loads back to utility and shut down the generator, saving fuel and standing ready to address the next utility failure.

• Listed to UL 1008 for optional standby systems, handling total system load including motors and all other electrical loads.
• cUL Listed for Canadian installations.
• Available in 100 through 400A ratings.

Benefits

• True double-throw contacts with inherent mechanical interlocking to prevent connection of generator and utility sources.
• Terminals for convenient connection of neutral and ground conductors.
• Working hand in hand with virtually every brand of generator, ASCO SERIES 185 Power Transfer Switches provide around-the-clock protection from a power failure, taking action only when required.
