SHUNT TRIP RELEASE COMPACT NSXM MX 400VAC

Compact NSXm – Efficiency that clicks

The Compact NSXm circuit breaker simplifies installation, reduces costs, and enhances operational continuity.

Small size and easy installation
The Compact NSXm circuit breaker (MCCB) is the smallest frame size in the Compact NSX range. The width of a 3-pole breaker is only 81 mm (4P / 108 mm). The Compact NSXm, 16-160 A, is therefore an ideal choice as a main or outgoing circuit breaker for electrical or control panels where space is limited and efficient operation is required. The breaker “clicks” directly onto a DIN rail without additional accessories. Mounting on an installation plate is also possible.
All breakers feature a standard mechanical indication on the outside of the enclosure for the electrical accessories installed inside the breaker.

Reliable connection
The Compact NSXm circuit breaker is supplied standard with EverLink™ tunnel terminals. Installation space requirements are reduced and costs are saved when a stripped conductor is connected to the EverLink terminal without cable lugs or touch protection covers. The innovative spring mechanism of the EverLink terminal compensates for changes in the conductor, preventing problems caused by loose connections. The EverLink terminal maintains the installed conductor at the correct tension without requiring retightening.

Efficient protection
The fast and efficient, rotative-actuated breaking of Compact NSXm circuit breakers during short-circuit conditions provides excellent current-limiting capability. This enables optimization of load-side Acti 9 circuit breaker selections in accordance with combined short-circuit protection, resulting in cost savings.

Easy to source
The Compact NSXm range includes 3- or 4-pole breakers with breaking capacities of either 16, 25, 36, 50, or 70 kA/400 V. The breaker part number always includes an integrated protective relay. The range also includes isolators and breakers with built-in earth leakage protection. Common accessories include auxiliary and alarm contacts compatible with PowerPact B and GV4 breakers, trip coils, door handles for the panel cover or side, torque screws, cable lugs and rail terminals, touch protection covers, and input-side EverLink terminals with control circuit output terminals.
