TIME IN SECONDS
The compact design of Littelfuse SLC series Class G fuses offers a cost
effective, space saving alternative to other fuse classes. The unique
design of the SLC series provides superior time-delay characteristics
over competitive products, which can increase system reliability and
minimize downtime. Class G fuses meet NEC requirements for branch
circuit protection and vary in length to prevent over-fusing when used
with the appropriate Class G fuse block.

Features/Benefits
• Current-limiting – Reduces damage to equipment caused by heating
and magnetic effects of short-circuit currents.
• 100,000 A.I.R. – Reliable interruption of all overcurrents up to
100,000 amperes.
• Time-Delay – Allows fuses to be sized closer to actual equipment
requirements and may reduce downtime caused by power surges.

Note: For applications where greater time-delay is required, or where
ratings exceed 60 amperes, consider selecting Littelfuse time-delay
Class RK1, RK5, J or CC fuses.
