LV431630 Electric NSX250F 36KA Compact MCCB
Schneider LV431630 250A 3P3D Electric Circuit breaker NSX250F 36KA Compact MCCB
Circuit breaker Compact NSX250F, 36 kA at 415 VAC, TMD trip unit 250 A, 3 poles 3d
NSX Molded Case Circuit Breakers is a full range of high performance molded case circuit breakers (MCCB) in 2 frame sizes designed to meet your needs from thermal-magnetic to advanced Micrologic trip units. This range will soon feature integrated earth leakage protection.
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
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.
Applications
An excellent choice for all standard and specific applications, including:
- Standard applications: industries, buildings, infrastructures
- Specific applications demanding high performance: marine, oil and gas extraction and processing, mining operations, metals and minerals production, and data centers
- Source-changeover systems (TransferPact): service sector (hospital operating rooms, computer rooms, ), industry (assembly lines, ship engine rooms, etc.), infrastructures (runway, railway, etc.)
