Semiconductor protection fuses
Operating class aR (partial-range semiconductor protection)
With slotted blade contacts for M10 screw fixing, or for installation in NH fuse bases or load-break switches
SITOR NH fuse links are designed for the overload and short circuit protection of cables, wires and power rails as well as for semiconductor protection

IEC 60269-2

When you need a fuse to boost safety in commercial and industrial applications, choose this NH fuse from Siemens. As a low-voltage type with a high rupture capacity, it's a practical pick for protecting cables, power rails and semiconductors against current surges or overvoltage. You can trust it to handle issues up to 250A and 1kV AC by breaking the connected electrical circuit to promptly stop the flow of electricity. This safeguards any linked components, as well as nearby users. The unit's slotted blade contacts let you make a secure connection whether you're fixing it in place with M10 screws, installing it in an NH fuse base or fixing it into a compatible load-break switch.

• Suits any mounting position for quick and easy installation
• Works in a broad range of temperatures from -20°C to +50°C
• Precision-made to a standard fuse size of C00 for broad compatibility
• High load factor of 0.95 means it uses electricity efficiently

There's an easy-to-read indicator built into the front of the device. This means checking the operating status of your fuse can be done at a glance.
