SERIES 185  SERVICE ENTRANCE RATED AUTOMATIC GENERATOR TRANSFER SWITCH

The series 185 Service Entrance Rated Automatic transfer switch has all of the features and functionality of the standard series 185, with the addition of a utility side circuit breaker.

The ASCO series 185 Service Entrance Rated Automatic Transfer Switch is fully rated and UL listed for use as "service entrance" equipment.

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 Power Transfer Switch is the other, the vital link that makes continuous power hassle free.

ASCO Series 185 Power Transfer Switches provide 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 Power 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 Power Transfer Switches provide around-the-clock protection from a power failure, taking action only when required.

ASCO Series 185 Power Transfer Switches are suitable for operation with portable or permanently mounted standby generators supporting loads up to 200 Amperes.
