CHINT NU6-II 2 Pole AC Surge Arrester, 385V / 460V, 40kA | VITS Pakistan

Product Overview

The CHINT NU6-II 2 Pole AC Surge Arrester is designed to protect electrical distribution systems and connected equipment against transient overvoltage caused by lightning and switching operations.

It helps divert surge energy away from sensitive electrical equipment, reducing the risk of damage to electrical installations, control systems and connected loads.

The NU6-II series is designed for AC power distribution applications and is available in different pole configurations and voltage ratings.

Technical Specifications

Important technical clarification: CHINT catalogue information distinguishes between:

• Imax: Maximum discharge current.
• In: Nominal discharge current.

The 40kA figure must be confirmed as Imax or In from the exact product marking and datasheet. Do not publish it as nominal discharge current until verified.

Key Features

• Protects electrical installations against transient overvoltage.
• Helps divert surge energy from sensitive equipment.
• Designed for AC electrical distribution systems.
• Two-pole configuration.
• Available in different operating-voltage configurations.
• Suitable for electrical distribution and control panels.
• Supports protection of connected electrical equipment against surge events.

Applications

• Main electrical distribution panels.
• Commercial electrical installations.
• Industrial distribution boards.
• Control panels and automation systems.
• AC power distribution networks.
• Electrical equipment surge protection.

Why Surge Protection Is Important

Transient overvoltage can occur due to lightning activity and switching operations. These voltage surges may damage sensitive electronic equipment, control devices and electrical components.

Installing an appropriately selected surge protective device helps divert surge energy and improve the protection of electrical installations.

Installation & Safety Notes

• Installation must be performed by a qualified electrician.
• Confirm the system voltage and earthing arrangement before selecting the SPD.
• Select the correct Uc rating for the electrical network.
• Verify the discharge current ratings from the exact model datasheet.
• Follow the manufacturer’s wiring diagram and installation instructions.
• Provide the recommended backup overcurrent protection.
• Ensure proper grounding and keep connecting conductors as short as practicable.
• Check the manufacturer’s status indicator and replacement instructions.

Frequently Asked Questions

1. What is the CHINT NU6-II surge arrester used for?

It helps protect AC electrical systems and connected equipment against transient overvoltage caused by lightning and switching operations.

2. What does 2 Pole mean?

It refers to the two-pole configuration of the surge protective device. The actual protection mode and wiring arrangement must be confirmed from the product diagram.

3. What does 385V / 460V mean?

These are maximum continuous operating voltage options. The correct version must be selected according to the electrical system.

4. What does 40kA mean?

The discharge-current rating describes the surge current the SPD is designed to handle under specified test conditions. Confirm whether 40kA refers to Imax or In for the exact model.

5. Can it be installed in an industrial distribution panel?

It can be considered for compatible AC distribution panels after verifying system voltage, earthing arrangement, protection coordination and the manufacturer’s installation requirements.
