FRONT PANEL COMPACT COMPACT COVER NSX400-630 AC

ComPacT NSX offers a complete range of high-performance compact circuit breakers (MCCB) in two frame sizes up to 630 A. Modular and easily configurable breakers are designed to meet your needs, from thermal-magnetic protective relays to extended protection and monitoring features with MicroLogic protective relays. Setting and selecting the breaker is easy thanks to updated Finnish online product selectors available at www.se.com/fi. The new generation of ComPacT NSX breakers provides an updated appearance along with innovative and versatile solutions for all electrical distribution applications. Benefits of the ComPacT NSX breaker:

Configurability:

• Reliable, safe, and easy connection of the protective relay to the breaker frame using torque screws enables simple and adaptable installation.
• Accessories for installation, control, monitoring, and operation are easy to install during initial setup or can be later modified to suit your needs.

Efficiency:

• The partially transparent cover allows quick identification of accessories installed on the breaker.
• Access breaker-related documentation easily on your smartphone via the QR code on the front of the breaker.
• Integrated earth leakage protection (MicroLogic Vigi protective relay), spring-connected electrical accessories, and standardized accessories optimize installation space and time, making selection and installation effortless.

Reliability:

• Roto-active™ breaker technology enhances system selectivity and enables optimization of device selection with combined short-circuit protection.

Connectivity:

• Depending on the selected protective relay and monitoring, control, and communication options, remote monitoring of electrical distribution can be easily implemented with ComPacT NSX breakers.
• The new wireless auxiliary and alarm contact enables transmission of trip and predictive alarm information for local communication and remote management. This enhances predictive maintenance and energy efficiency.
