Blade Terminal & Special Purpose Fuses

Low Voltage

RoHS

MAXI

42V Fuse

Slo-Blo Type Fuse

• Same performance characteristics as the industry standard MAXI, but

modified to work in the 42 volt environment

• Unique design prevents lower rated fuses from being inserted into

the circuit

• Backwards compatibility with 12 volt circuits

• Based on proven technology

• Mates with industry standard terminals
