NF125-SXV

The NF125-SXV is a molded case circuit breaker (MCCB) from Mitsubishi Electric’s WS-V World Super V Series, belonging to the NF-S standard class lineup. Designed for low-voltage power distribution and protection applications, this breaker is built to open and close low-voltage circuits while reliably interrupting fault currents caused by overloads or short circuits. With a 125A frame current rating and thermal-magnetic trip mechanism, it delivers dependable overcurrent protection across a wide range of industrial and commercial electrical installations.NF125-SXV

This unit is listed as NNB (New Never Been Used/Installed), meaning it has never been placed into service and retains its full factory-specified performance characteristics. Buyers benefit from the complete operational life of the breaker — a significant advantage over refurbished alternatives when protection integrity and long service life are priorities. The WS-V series incorporates advanced arc interruption technology engineered to meet the rigorous demands of modern power distribution panels, machinery control centers, and building automation systems.NF125-SXV

The NF-SXV designation places this product in the standard-class tier of the NF125 family, offering a balanced combination of breaking capacity and cost efficiency. It is compatible with a broad range of Mitsubishi Electric accessories including auxiliary contacts, alarm switches, shunt trip units, and undervoltage releases, making it a versatile choice for engineers specifying protection devices in new builds or replacement scenarios. Its compliance with IEC 60947-2 ensures interoperability with internationally standardized switchgear and controlgear systems.NF125-SXV

Whether you are maintaining an existing facility, expanding a distribution board, or sourcing surplus industrial electrical components, this breaker represents a reliable, brand-name solution backed by Mitsubishi Electric’s reputation for quality in power distribution products. Purchasing a genuine, unused component from the WS-V family ensures your installation benefits from proven arc-quenching performance and a thermally stable molded case housing designed for long-term service in demanding environments.
