Compact circuit-breaker Compact NSXm

ComPacT NSXm is the smallest frame size of molded case circuit breakers. Thanks to its convenient design, its use is efficient and easy in 16 to 160 A applications.

Advantages of the ComPacT NSXm breaker:

• Thanks to the partially transparent cover, you can quickly identify the auxiliaries installed on the circuit breaker.


• You can easily get the documents related to the circuit breaker on your smartphone using the QR code on the front of the circuit breaker.


• Residual current protection integrated in the circuit breaker (circuit breaker with MicroLogic Vigi protective relay), spring-type electrical auxiliaries and standard auxiliaries saves installation space and time for effortless selection and installation.:


• The Roto-active™ disconnection technology improves the selectivity of the electrical system and enables the optimization of instrument selections through combined short-circuit protection.


• The new wireless auxiliary and alarm contact enables information about triggers and predictive alarms for local communication and remote control. This enhances predictive maintenance and energy efficiency.


• Small size: Width 81 mm (3P) / 108 mm (4P) x Height 137 mm x Depth 80mm


• Rated current: 16 - 160 A


• Breaking capacity 400 V: 16, 25, 36, 50 or 70 kA / 400V


• Number of poles: 3 and 4


• Trip unit options (embedded into the frame): Thermal-magnetic TM trip unit relay or electronic MicroLogic Vigi trip unit with built-in residual current protection (30mA - 1A)


• Installation: To DIN rail without additional accessories or installation on a base plate


• The spring mechanism of the EverLink™ terminal compensates for the changes in the conductor, preventing the problems caused by overheating from loose connections


• The EverLink™ tunnel terminals embedded to the breaker also save costs and installation space on the input and output side, as there is no need to purchase and install separate cable lugs and contact protectors
