Adhering to international standards ensures the safety, reliability, and interoperability of electrical components and systems in electrical engineering. Four key standards for low-voltage applications include IEC 60077-3, IEC 60269-2, IEC 60947-2, and IEC 60947-3. Each of these standards addresses specific aspects of low-voltage equipment and its safe operation.

IEC 60077-3 is crucial for railway applications , focusing on electric equipment used in rolling stock. This standard outlines requirements for constructing, performing, and testing low-voltage switchgear and control gear. Compliance ensures the electrical systems within trains are safe, reliable, and capable of withstanding harsh railway conditions.

IEC 60269-2 specifies requirements for low-voltage fuses , particularly for use by authorized personnel in industrial settings. This standard ensures that fuses provide adequate protection against overcurrents, preventing potential equipment damage and ensuring personnel safety. It includes guidelines for the performance, dimensions, and marking of fuses.

IEC 60947-3 addresses requirements for switches, disconnectors, switch-disconnectors, and fuse-combination units used in low-voltage applications. This standard ensures these devices can safely and effectively isolate electrical circuits, providing crucial safety during maintenance and emergencies. It includes specifications for construction, performance, and testing.

The LPHV Series dead front fuse holders are a touch-safe design providing protection to personnel when installing and removing fuses. They are intended to house midget-sized 1000 V fuses. These fuse holders are not designed for load break, but they are ideal for isolating photovoltaic module strings for maintenance and meet UL requirements for 1000 V solar fuse protection. The compact fuse holder mounts quickly onto a 35 mm DIN rail, decreasing panel layout and assembly time. They are available in 1-, 2-, 3-, and 4-pole configurations, or they can be connected together with a Littelfuse multi-pole assembly kit (sold separately). The LPHV series has been self-certified to stringent Littelfuse standards for applications upward of 1000 V dc. These fuse holders meet IEC 60269-2, -4, and -6 performance requirements.
