Automatic Transfer Switches
Click to enlarge electrical diagramFully Automatic
All of our switches monitor utility and generator voltages and will automatically connect to the appropriate source of power. The 100 amp and 200 amp switches are capable of "whole house" power transfer in residential and small business applications. For whole house applications the switch amp rating must equal or exceed the utility service rating.Safety Features
All switch models are solenoid-operated from utility or generator inputs and contain electrical interlock switches to eliminate the possibility of dangerous back feed to utility during an outage.
Pick options using dropdown menus before pressing add to cart button...
1-Select proper switch for your application. Optional built-in service entrance disconnect eliminates need
for external disconnect when installing switch directly downstream of utility meter. Reduces installation
time and cost of extra external disconnect. ACCM will control up to two A/C units or heat pumps by
wiring these contacts into thermostat circuit.
2-Select optional remote StatStation for displaying genset conditions (soon to be discontinued)
3-Select Command Central when more than two loads must be controlled. Provides four normally closed
control contacts for controlling up to four A/C units or heat pumps by wiring these contacts into thermostat
circuits. Also provides four 50A 240V contactors for controlling four other large loads such as electric
water heater, electric range, electric dryer, etc.
4-Select cold weather package for reliable starting below freezing.
5-Optional maintenance kit. Includes oil, filters, plugs, etc.
6-Select delivery method.
