Description
Features
The ComPact NSX molded case circuit breaker (MCCB) range is designed to optimize space and breaking capacity. The range comes in two frame sizes with a variety of optional functions and accessories.
Specifications:
- Flexible installation: any position; switchboard or wall-mounted
- Nominal current: 16 to 630 A
- 9 Breaking capacities for the 2 sizes of circuit breakers:
– up to 250 A: 25, 36, 50, 70, 100, 150, 200 kA at 415 V
– up to 630 A: 36, 50, 70, 100, 150, 200 kA at 415 V
– both size of circuit breakers with 75 & 100 kA at 690 V - 1, 2, 3 and 4 pole versions available
- Large range of electronic and thermal-magnetic protections
- Advanced trip unit with integrated power metering: I, U, P, E, THD, f, CosPhi
- Interchangeable trip-units to upgrade your panel with smarter functions
- Plug and ready wiring system and communicating accessories
- Wealth of options for auxiliaries and accessories (field installable)
- Integrated earth leakage protection via MicroLogic Vigi (earth leakage circuit breaker – ELCB)

Benefits
Easy and efficient
- Two standardized frame sizes for your convenience
- Save space, time and effort with integrated earth leakage protection (ELCB), in the molded case circuit breaker (MCCB) frame size
- Easy to swap trip units and standardized accessories over time
- Wide range of online and offline software tools that help to improve productivity at all stages of your project (Product Selector, EcoStruxure Power Design – Ecodial, EcoStruxure Power Build – Low Voltage, EcoStruxure Power Commission)
Optimize safety
- Highly resistant to environmental stresses
- Roto-active breaking technology helps to reduce early aging effects and increase operation lifespan
Measure and Communicate
- Local and remote communication with trip alarm (earth leakage, overload, short circuit) and pre- alarms (earth leakage) allowing you to proactively increase operational and energy efficiency
- Advanced MicroLogic trip unit can assist in providing corrective, preventative and predictive maintenance and energy management to identify potential savings
Working with communication devices, the ComPact NSX inside our Smart Panels becomes an EcoStruxure connected product within our EcoStruxure Power architecture.
