Class-T fuses provide the ultimate protection for high power circuits where extremely fast fuse blow characteristics are required.
Modern batteries such as AGM and Lithium ion Phophate (LifePO4) technologies are capable of very high short-circuit currents which may be beyond the interrupt rating of standard circuit breakers and other fuse types.
Class-T fuses are also recommended for use with high power inverters and inverter/chargers.
Fuses are available in continuous current ratings of 110-600A, However we only currently stock the 300a and 400a versions to suit the carrier we carry.
 
Note:
Occasionally our supplies may alter between both Littelfuse and Bussman, We can not guarantee which brand you will receive.
