The AVP303 is a Three Phase Automatic Voltage Protector which protects against over voltage and under voltage on any one of the three phases as well as loss of one or more phases. Indication and/or disconnection as a result of mains frequency error of phase sequence error is available as an option.
The AVP303 incorporates a contactor to switch the full load current. The AVP303-xx is available in different sizes ranging from 23Amps to 500Amps (the -xx relates to the model number, ie: AVP303-23 is a 23Ampper phase AVP303).
