AC 230V Protection Relay

TOMZN 3 IN1 Voltage Protector Features

• Adjustable Over-Voltage Protection – Cuts off power if voltage rises above your set safe level (e.g., 230–300 V range).

• Adjustable Under-Voltage Protection – Disconnects supply when voltage falls below the safe limit (e.g., 140–210 V range).

• Adjustable Over-Current Protection – Protects against excessive current with adjustable current range up to 63 A.

• Real-Time Monitoring – Built-in voltage meter, ammeter, and energy (kWh) meter for live electrical data.

• Delay & Reconnect Settings – Adjustable delay times before protection kicks in and automatic power reconnection after normal conditions return.

• Memory of Fault Values – Saves recorded values for over-voltage, under-voltage, and over-current events even after power is off.

• LED Indicators – Flashing LEDs show voltage or current protection status when triggered.

• DIN-Rail Mountable – Fits easily into electrical panels using a standard DIN rail.
