Bussmann DIN ‘S’ Fuse Links
The time current characteristics of the ‘S’ range is optimised to ensure improved discrimination with upstream devices
and to give fast clearance of earth faults in the secondary terminal zones. The breaking performance with low over
currents is adequate to cater for all normal distribution applications, where low voltage fuse links on the secondary side
take care of low overload faults, leaving the high voltage fuse links to clear major faults ahead of LV protection. The fuse
links are suitable for use even where there is no secondary LV protection, provided that they are used in fuse switches
fitted with instantaneous striker tripping.
Bussmann DIN ‘F’ Fuse Links
The ‘F’ range fuse links have ‘full range’ clearing capability. Bussmann ‘F’ types are designed to clear all overloads right
down to fuse’s rated current in accordance with latest IEC 282-1 requirements. They are thus suitable for use as a sole
form of protection. ‘F’ range time current characteristics are especially advantageous for transformer protection
applications.
Bussmann DIN ‘A’ Fuse Links
This earlier, well proven design, has values of minimum breaking current between the ‘S’ and ‘F’ range including higher
current ratings.
