Automatic 3-Phase to 1-Phase Selector

Tired of voltage fluctuations damaging your appliances every time the power supply goes haywire? The amiciKart Intelligent 3-Phase to 1-Phase Changeover Switch automatically selects the healthiest available phase in seconds — giving your home, office, or industrial setup uninterrupted, protected power without any manual intervention.

This 63A automatic transfer switch continuously monitors all three incoming phases and instantly switches to the best one the moment it detects overvoltage, undervoltage, or overcurrent conditions. A bright built-in LED display shows live voltage readings across all three phases and real-time current consumption — so you always know exactly what's happening with your power supply. You can also set your own priority phase and customise cut-off thresholds to match your specific load requirements, making this switch equally suited for residential wiring boards, commercial setups, and light industrial panels.

Unlike basic manual changeover switches, this unit combines triple-layer protection (over-voltage, under-voltage, and over-current) with fully adjustable settings — extending the lifespan of your connected appliances and reducing costly downtime. Installation is straightforward for any licensed electrician, and the compact DIN-rail compatible design fits neatly into standard distribution boards.

Original product FAQs

What is the maximum current rating of this changeover switch, and is it suitable for heavy loads like air conditioners or water pumps?

This switch is rated at 63A, making it suitable for heavy household and light industrial loads including air conditioners, water pumps, and refrigerators. Ensure your total connected load does not exceed 63A on the selected phase to avoid tripping.

What voltage range does this switch monitor, and what are the default over-voltage and under-voltage cut-off values?

The switch monitors standard 230VAC single-phase output derived from a 3-phase supply. The over-voltage and under-voltage cut-off thresholds are adjustable, allowing you to set custom trip values based on your local grid conditions and appliance sensitivity — the default settings are pre-configured for typical Indian grid fluctuations.

Can I set one phase as the primary/priority phase, and how does the switch decide which phase to switch to?

Yes, the switch allows you to assign a priority ranking to each of the three input phases. It will always prefer the highest-priority phase when it is within the healthy voltage range, and automatically fall back to the next available phase only when the priority phase is outside the set thresholds.

Is this switch compatible with a standard DIN rail distribution board, and does it require a neutral connection?

The switch is designed for DIN-rail mounting and fits into standard modular distribution boards used in Indian residential and commercial installations. It operates on a 3-phase + neutral input configuration, so a neutral connection is required for proper operation and accurate voltage sensing.

How fast does the switch transfer between phases, and will there be a noticeable power interruption during the changeover?

The automatic phase changeover happens within a few seconds of detecting a fault condition on the active phase, which may cause a brief interruption similar to a momentary power blink. This switch is designed for load transfer applications and is not a no-break UPS-type device, so sensitive equipment like computers should be used with a UPS in addition to this switch.
