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
