Tronic Automatic Voltage Switcher 3 Phase

The Tronic Automatic Voltage Switcher 3 Phase is a high-reliability device designed to protect industrial and commercial electrical systems from voltage irregularities and phase faults. It continuously monitors all three phases and disconnects power in case of over-voltage, under-voltage, phase loss, or incorrect phase sequence, helping to prevent costly damage to sensitive equipment. Ideal for protecting entire buildings, machinery, or three-phase air conditioning and refrigeration units, this switcher provides peace of mind in demanding electrical environments. Its weather-resistant IP66 housing and adjustable time delay make it suitable for both indoor and outdoor installations.

Product Features

Three-Phase Voltage Monitoring

Continuously monitors over-voltage, under-voltage, and phase loss on all three phases to prevent electrical damage to connected equipment.

Phase Sequence and Frequency Error Indication

Equipped with functionality to detect phase sequence errors and mains frequency anomalies, offering comprehensive monitoring of incoming power quality.

Adjustable Delay Timer

Allows the user to set a delay period between 10 seconds and 10 minutes before reconnecting power after a fault clears, preventing rapid cycling or surge damage.

High Compatibility and Control

Controls any size contactor or external three-phase controller, making it ideal for large loads and critical equipment.

Weatherproof Construction

Enclosed in a durable IP66-rated PVC casing, ensuring protection against dust and powerful water jets, suitable for harsh environments.
