2 Pole Voltage Protector Relay

CNKA is a well-known Chinese supplier that provides wholesale of its brand's 2 pole voltage protector relay. These devices are designed specifically for single-phase AC 220V, 50Hz circuits with a rated current of 63A, making them an ideal choice for protecting residential distribution boxes or wires supplying power to single-phase equipment.

Equipped with a digital display and manufactured with imported modular electronic components, it has high reliability and performance. The protector automatically and quickly cuts off the power supply during abnormal voltages (such as overvoltage, undervoltage, or grid fluctuations) and restores power supply after the voltage returns to normal.

In summary, CNKA's voltage protectors provide powerful protection and intelligent recovery, helping to ensure the safety and stability of electrical systems.

CNKA voltage protector Parameter (Specification)

Feature

1.In the event of sudden or instantaneous overvoltage, the protector does not support multi-function circuit protection.

2.Because the contact line is not directly from the power source, and due to issues like unstable voltage, the protector may not effectively handle sudden power on/off scenarios.

3.It meets the III electrical safety standard with an impulse withstand voltage of up to 4kV.

4.The 2 pole voltage protector relay features a modular design for easy track installation, enhancing its appearance and functionality.

FAQ

Q: What is undervoltage protection?

A: Undervoltage protection, also known as low-voltage protection or LVP, refers to the feature within circuits that prevents automatic restart of loads after a power outage, requiring manual intervention to restore normal operation.

Q: Can undervoltage cause damage?

A: Undervoltage can potentially damage equipment because motor-driven appliances and certain electronic power supplies draw increased current at lower voltage levels, leading to possible overheating.

Q: What causes overvoltage?

A: Overvoltage occurs due to inadequate regulation of power supplied by utility companies, oversized transformers, uneven or fluctuating circuit loads, wiring errors, and failures in electrical insulation or isolation. These issues can result in voltage surges that may harm connected devices.
