Class-T fuses provide the ultimate protection for high power circuits, and where extremely fast fuse blow characteristics are required. Modern batteries such as AGM and lithium 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. The fuses come in one of three different sizes, depending on their current rating, so must be used with the correct holders as follows:

• 110-200A - use with fuse holder P04058
• 225-400A - use with fuse holders P03342, P04057, or P04059
• 450-600A - use with fuse holder P03343

Note: These fuses are manufactured by both Littelfuse and Bussman, and we cannot guarantee which brand you will receive.
