The ComPacT NSXm160B is one of the smallest molded case circuit breakers on the market, with dimensions of only 108 mm wide, 137 mm high, and 80 mm deep. This compact design allows for easy integration into electrical cabinets and power distribution systems, occupying minimal space without sacrificing protection capability. Its reduced size is ideal for applications where space is limited and a high-performance protection solution is required.

This model incorporates Schneider Electric's innovative Everlink technology, which ensures a stable and secure connection, even in environments with vibrations or thermal fluctuations. Everlink reduces the risk of loose or faulty connections, enhancing system safety and long-term operational reliability. Additionally, the circuit breaker offers the option of mounting on DIN rail or plate, providing additional flexibility in installation, adapting to different electrical panel configurations.

The built-in thermal-magnetic control unit (TMD) in the ComPacT NSXm160B provides adjustable protection against thermal overloads and short circuits, ensuring that the electrical system is protected against current variations that could damage equipment or compromise installation safety. This control unit combines thermal protection with a long delay (L) for overloads, magnetic protection with a short delay (I) for short circuits, and instantaneous protection (G), ensuring a quick and precise response to any electrical fault.
