Fuses For Semiconductor Protection
Knife Blade Contact – German Standard |
SIBA ultra-rapid knife blade contact fuses type NH are available in many different sizes and four voltage ratings. They follow DIN/VDE -
IEC standard and can be fitted in open fuse bases. Usage in fuse bases or switches requires the comparison of the power loss of the fuse with the power acceptance of the base or
switch.
All SIBA type NH-fuses are available with either integral blown fuse indicator or a separately fitted trip indicator fuse for microswitch
operation.
Class: aR/gR
