NF125-HV

The NF125-HV is a high-performance class moulded case circuit breaker (MCCB) from Mitsubishi Electric’s WS-V World Super V Series, engineered to deliver robust overcurrent and short-circuit protection across a wide range of industrial power distribution and machinery applications. Belonging to the NF-H high-performance tier, it is designed to meet the demanding needs of modern electrical panels and distribution boards, offering a rated frame of 125A with available pole configurations in 2-pole and 3-pole arrangements, where the 2-pole version is derived from the 3-pole model with the central pole removed.NF125-HV

Built around a thermal-magnetic fixed trip unit, this breaker provides dependable overload and short-circuit protection without the need for external adjustments, making it well suited for panel builders and industrial equipment manufacturers who require consistent, repeatable protection performance. The WS-V Series platform incorporates advanced breaking technology that achieves high interrupting capacity ratings across voltages ranging from 200V AC up to 690V AC, with a rated insulation voltage of 690V, covering a broad spectrum of global grid voltages and making it compatible with both European and Asian electrical infrastructure standards.NF125-HV

With a short-circuit breaking capacity (Icu) of up to 100kA at 200V AC and 50kA at 400V AC per IEC 60947, this breaker offers class-leading fault protection for its frame size, reducing the risk of equipment damage during high-energy fault events. The front lugs or bars connection interface simplifies installation within standard enclosures and switchgear. Whether sourced as new-never-before-used (NNB) surplus or as a verified used unit, this component represents a cost-effective path to maintaining or expanding reliable electrical protection in commercial and industrial settings.NF125-HV

As a genuine product in the Mitsubishi Electric low-voltage protection lineup, this circuit breaker is backed by an established engineering heritage and is recognized internationally under IEC 60947 standards. It is an ideal replacement or spare part for facilities managing panel upgrades, machinery refurbishment, or MRO inventory, offering full compatibility with the broader ecosystem of accessories and auxiliary devices available for the NF125 frame series.
