LOAD BREAK SWITCH LEVER NSX160NA LOAD SWITCH 160A 3P

The ComPacT NSX range covers a wide selection of high-performance compact circuit breakers (MCCBs) in two frame sizes up to 630 A. Modular and easily configurable breakers are designed to meet various needs, from thermal-magnetic protective relays to extended protection and monitoring features with MicroLogic protective relays.

Defining and selecting the breaker is easy using the Finnish online product selectors on www.se.com/fi.

The new generation of ComPacT NSX breakers offers 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 can be easily installed during initial setup, or you can later modify the breaker’s functions according to your needs.

Efficiency:

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

Reliability:

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

Connectivity:

• Depending on the selected protective relay and monitoring, control, and communication options, you can easily implement remote monitoring of the electrical distribution system 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.
