{"title":"NH Knife-Blade Fuses","description":"\u003cp\u003eNH and knife-blade fuses provide reliable overcurrent and short-circuit protection in industrial distribution boards, main switch panels, and commercial installations. Built to IEC standards, they handle high fault currents safely and are available in standardised sizes from 000 through 3, making it straightforward to find a direct replacement or spec a new panel. Our carefully selected range covers common gG\/gL current ratings for both general-purpose circuit protection and cable protection.\u003c\/p\u003e\u003ch3\u003eChoose the right size and rating\u003c\/h3\u003e\u003cp\u003eNH fuses are classified by physical size (000, 00, 1, 2, 3) and current rating in amperes. The fuse must match the base size in your holder or fuse switch and must not exceed the cable's rated current. Always use the characteristic that matches the load: gG for general circuits, gL for cable-only protection.\u003c\/p\u003e\u003ch3\u003eVoltage and breaking capacity\u003c\/h3\u003e\u003cp\u003eCheck that the fuse's rated voltage covers your system voltage (typically 400 V AC for three-phase industrial circuits) and that its breaking capacity is sufficient for the prospective short-circuit current at that point in the installation.
