AVS303-xx

The AVS303 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.

Fully automated switch with no moving parts, the AVS303 incorporates a contactor to switch the full load current (see the AVS3P-0 if you already have switching mechanism in place).

The AVS303-xx is available in different sizes ranging from 23 amps to 1250 amps (the –xx relates to the model number, i.e. AVS303-23 is a 23 amp per phase AVS303).

Protect against

• High voltage
• Low voltage
• Spikes/surges
• Powerback surges
• Any two phases shorting together

Ideal for:

• 3 phase air conditioning
• Industrial refrigeration
• Industrial plants and machinery

Max power: From 23 amps per phase and up to 1250 amps

Wait time: User adjustable from 10 seconds to 10 minutes
