Undervoltage release for NZM2/3 NZM2/3-XU110-130AC 259497

Undervoltage release for NZM2/3 circuit breakers

This undervoltage release, designed for the NZM2 and NZM3 series circuit breakers, provides additional protection for the electrical installation against the effects of voltage drops. This is particularly important in applications sensitive to voltage fluctuations, where stable power is crucial for the correct operation of devices. The device reacts to a voltage drop in the range of 110-130V AC, allowing for a quick response and disconnection of the circuit in case of power supply problems.

Functionality and application

The NZM2/3-XU110-130AC release is dedicated to working with cam switches, which ensures precise and reliable operation. Its main task is to monitor the control voltage and trigger the disconnecting mechanism when the voltage drops below the set threshold. This protects not only the connected devices, but also the circuit breaker itself from overload caused by incorrect operation. Installation is done via a screw connection, which guarantees a solid and durable electrical connection.

Key features and benefits

• Protection against undervoltage: Provides reliable protection against the effects of insufficient supply voltage, which extends the life of connected devices.
• Compatibility: Designed for Eaton NZM2 and NZM3 series circuit breakers, guaranteeing a perfect fit and easy installation.
• Fast response: Reacts to a voltage drop in the range of 110-130V AC at both 50Hz and 60Hz, ensuring a quick disconnection of the circuit if necessary.
• Solid connection: Uses a screw connection, ensuring a secure and durable electrical connection.
• No auxiliary contacts: The lack of switching, normally open or normally closed contacts simplifies the design and increases the reliability of the device.
• Compliance with standards: The product meets the appropriate safety standards (has the CE marking), which confirms its high quality and safety of use.

It is important to choose the correct release for a specific application and to regularly check its technical condition to ensure optimal protection of the electrical installation. This release is a protective element of the installation – it does not function as a motor starter or overload relay.
