Blade Fuses
A blade fuse (NH fuse) is a high breaking capacity fusible fuse link fitted into a base or a fused load break switch by the blade contacts at its two ends. It is used in low-voltage main distribution and power factor correction panels, at transformer outputs, and on motor and drive supply lines for overcurrent protection. Siemens, ABB and Tibcon fuse links are listed in sizes such as NH000, NH00, NH1, NH2, NH3 and NH4 and in rated currents such as 125 A, 160 A, 250 A, 400 A and 630 A; besides general-purpose gG types, Siemens 3NE series semiconductor protection fuses are also available. Choose the blade fuse according to its size, rated current, rated voltage and duty class (gG for cable and line protection, aM for motor circuits, aR or gR for semiconductor protection). The size of the fuse link must be compatible with the size of the base or fused load break switch; bases are in a subcategory. The NH fuse system is defined in the IEC 60269 series of standards; a blown fuse link is not repaired but replaced with a new one of the same size, class and current rating.

How to choose Blade Fuses
A blade fuse (NH fuse) is a high breaking capacity fusible fuse link fitted into a base or a fused load break switch by the blade contacts at its two ends. It is used in low-voltage main distribution and power factor correction panels, at transformer outputs, and on motor and drive supply lines for overcurrent protection.
- Separate overcurrent/leakage protection, motor starting and local isolation requirements.
- Select rated current, pole count and breaking capacity (kA) from the installation calculation.
- Match coil voltage, auxiliary contacts and tripping curve to the control circuit and load type.
