nm8-uv230-630 chint under voltage release 230v for nm8-250-630

Why Choose the Chint NM8-UV230-630 Under Voltage Release?

The Chint NM8-UV230-630 is a genuine 230 V AC under voltage release designed for Chint NM8-250, NM8-400 and NM8-630 moulded case circuit breakers (MCCBs). It provides automatic tripping when the control voltage falls below a safe operating level, helping to protect electrical equipment from unsafe low-voltage conditions.

As part of the Chint NM8 MCCB accessory range, this under voltage release integrates directly with compatible breakers to improve safety, reliability and control within low-voltage power distribution systems. It is commonly used where machinery, motors or critical circuits must be disconnected during voltage loss.

With a 230 V AC operating voltage, the NM8-UV230-630 is suitable for industrial control panels, commercial switchboards, OEM machinery and electrical distribution assemblies requiring dependable under voltage protection.

Reliable Under Voltage Protection for MCCB Installations

Under voltage releases are used to ensure that connected circuits are disconnected when the supply voltage drops below an acceptable level. This helps prevent equipment from running under unstable electrical conditions, reducing the risk of faults, overheating or unsafe operation.

The Chint NM8-UV230-630 is particularly useful in machinery and power distribution systems where loss of voltage must result in a controlled trip. It also helps prevent equipment from restarting unexpectedly when power is restored, improving operational safety for maintenance teams and operators.

Typical Applications

• Industrial control panels.
• Commercial power distribution boards.
• Motor control centres.
• Machine safety and automation systems.
• OEM electrical equipment.
• Switchboard upgrades and maintenance projects.
