Overcurrent release NZM2/3-XA208-250AC/DC 259763

Overcurrent release for Eaton NZM circuit breakers – reliable starting and protection

This overcurrent release, catalog number 259763, is a key component of the NZM, N(S)2(-4), NZM3(-4) and N(S)3(-4) series circuit breakers. Designed to work with cam switches, it enables remote starting and control of circuit breakers while ensuring a high level of safety. Thanks to the ability to operate in both AC and DC circuits (208…250V), it offers a wide range of applications in various electrical installations.

Functionality and application

The overcurrent release allows circuit breakers to be started using a voltage pulse or constant voltage. This solution is particularly useful in applications requiring remote control, process automation or providing an additional level of protection against accidental switching on. When the control voltage is applied, the release blocks the possibility of direct contact with the main switch contacts, minimizing the risk of electric shock.

It is worth remembering that the operating current release is not compatible with the leading NZM..-XHIV.. auxiliary switch or the undervoltage release NZM..-XU....

Key features and benefits

• Voltage versatility: Possibility of powering with alternating current (AC 50/60 Hz) and direct current (DC) in the range of 208-250V.
• Safety: Blocking of the main contacts when the control voltage is applied ensures protection against accidental contact.
• Compatibility: Designed for a wide range of Eaton NZM and N(S) series circuit breakers.
• Easy installation: Belongs to the family of accessories for LZM/LN and NZM/N circuit breakers, which facilitates integration with existing installations.
• Flexibility: Possibility of starting via pulse or constant voltage – adaptation to the specifics of the application.
• Solid connection: Uses a screw connection for a reliable and durable electrical connection.

This release is characterized by a screw connection. The rated control voltage Us is 208…250V for both DC and AC 50/60 Hz. It is not intended for use as a switch, motor starter or overload relay, but works perfectly with cam switches.

This release is an optimal solution for installers looking for a reliable and safe way to remotely control Eaton circuit breakers and for end users who value convenience and functionality.
