Undervoltage release NZM4-XU110-130AC 266192

Undervoltage release – protection against voltage drop

The NZM4-XU110-130AC undervoltage release is a protective element for Eaton NZM series circuit breakers, designed to disconnect the circuit in the event of a voltage drop. Its function is to ensure the safety of the installation and connected devices, protecting them from damage caused by too low voltage. This solution is particularly useful in applications where voltage stability is crucial for the proper operation of equipment.

Functionality and application

The device reacts to a voltage drop in the range of 110-130V AC (50/60 Hz), which allows for effective protection of sensitive devices. This release does not have any switching, normally open or normally closed contacts – its function is limited to monitoring the voltage and initiating the circuit breaker shutdown when the permissible threshold is exceeded. Installation is done via screw connection, ensuring a secure and durable electrical connection.

The NZM4-XU110-130AC undervoltage release is primarily used in:

• electrical installations in commercial and industrial buildings,
• control cabinets,
• uninterruptible power supply (UPS) systems,
• equipment requiring stable power supply.

Characteristics and compatibility

The device is dedicated to working with Eaton NZM4 molded case circuit breakers. Please note that this release is not intended for use with motor circuit breakers, overload relays or overload protection relays. Its construction is based on AC technology, which means it cannot be used in DC circuits. Thanks to this, you can count on reliable operation and precise response to voltage changes in the AC system.
