SERIES 185  AUTOMATIC TRANSFER SWITCH

24 HOUR PROTECTION AGAINST POWER FAILURES

Residential power outages can jeopardize homeowner personal safety and comfort, and also cause millions of dollars in damages to small businesses each year.

Computers, communications, air conditioning, security systems, refrigerators and freezers, hot water heaters and sump pumps all depend on electrical power to operate.

A generator is one piece of the solution. An ASCO Series 185 Automatic Transfer Switch is the other, the vital link that makes continuous power hassle free.

THE ASCO Series 185 Automatic Transfer Switch provideS all  the intelligence your generator needs to make sure the power stays on when utility power fails. Sensing the loss of utility power and signaling the generator to start and restore power to your home or business – even if no one is home. When utility power has been restored, the Series 185 Automatic Transfer Switch automatically transfers your vital loads back to the utility and shuts the generator down.

Working hand in hand with virtually every brand of generator, ASCO Series 185 Automatic Transfer Switches provide around-the-clock protection from a power failure, taking action only when required.

ASCO Series 185 Automatic Transfer Switches are suitable for operation with portable or permanently mounted standby generators supporting loads up to 400 Amperes.
