Overcurrent Trip Unit NG125 MX+OF – Reliable Protection and Flexibility

The NG125 MX+OF overcurrent trip unit is a component used to expand the functionality of Schneider Electric NG125 series residual current circuit breakers and overcurrent circuit breakers. It enables the addition of an overcurrent tripping function, which increases the safety of the electrical installation by protecting against sudden voltage surges. This is particularly important for devices with induction motors or other loads generating inrush currents.

This model is compatible with a wide range of control voltages – both AC (230-415V for 50Hz and 110-415V for 60Hz), and DC (110-130V). This allows it to be used in various types of installations, both in residential and industrial buildings. This trip unit is not intended for use with motor circuit breakers or overload relays, but works perfectly with residual current circuit breakers and overcurrent circuit breakers.

Versatility and Easy Installation

The NG125 MX+OF overcurrent trip unit is characterized by a screw connection, which ensures a secure and durable electrical connection. Its versatility makes it an ideal choice for both professional installers and end-users looking for a reliable solution to protect their installations. The ability to connect to busbars simplifies installation and configuration in electrical panels. Additionally, the K60 series is characterized by compatibility with any busbar available on the market.

Advantages in points:

• Wide range of control voltages: AC 230-415V (50/60Hz) and DC 110-130V – ensures application flexibility.
• Overvoltage protection: The overcurrent tripping function protects against sudden voltage surges, increasing installation safety.
• Compatibility: Designed to work with Schneider Electric NG125 series residual current circuit breakers and overcurrent circuit breakers.
