3 Phase Automatic Phase Selector with Voltage, Ampere Meter and Adjustable Protection 100A

Description

1- Power On Delay Time (Adjustable 1-600s)

Built-in power-on delay prevents sudden voltage spikes, protecting sensitive equipment during startup.

2- Protection Recovery Delay (Adjustable 1-600s)

Smart recovery delay ensures stable voltage and current before reconnecting power after a fault.

3- Under Voltage Protection (Adjustable 80-220V)

Automatically disconnects power when voltage drops below safe levels to prevent motor and appliance damage.

4- Over Voltage Protection (Adjustable 110-300V)

Instantly cuts off the supply during high voltage to safeguard industrial and commercial equipment.

5- Over Current Protection (Adjustable 1-80A)

Provides adjustable over-current protection up to 100A to prevent overheating and electrical failures.

6- Over Current Protection Action time (0.1-10s)

Automatically trips the system within an adjustable 0.1 to 10 seconds when the current exceeds the set limit, protecting equipment from overload and short-circuit damage.

7- Over Current Protection Frequency (0–20)

Adjustable over-current trigger frequency (0–20) allows precise tuning for different load behaviors.

8- Voltage & Ampere Meter

Real-time voltage and current display enable accurate monitoring of all three phases.
