Introduction

Molded case circuit breakers (MCCBs) and low-voltage power circuit breakers (LVPCBs) provide vital functionality for low-voltage power distribution systems and processes – protecting connected devices from both overloads and short circuits. A safe, economical, and effective way to connect and disconnect loads from the electrical source, MCCBs and LVPCBs are pervasive and applied across industries, including applications where uptime is critical

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.

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.
