Littelfuse SLC Series Class G Time-Delay Cartridge Fuse, 480VAC

Littelfuse SLC Series Class G Time-Delay Cartridge Fuse, 480VAC

The Littelfuse SLC Series is a line of compact Class G time-delay cartridge fuses rated 480VAC, available in ampere ratings from 6A to 50A to match branch-circuit protection needs across industrial and commercial electrical systems. Each fuse in the series delivers a medium time-delay opening characteristic (medium-acting/medium time lag/medium time delay) that reduces nuisance downtime caused by harmless power surges or equipment inrush demands, backed by a 100,000 ampere interrupting rating (A.I.R.) for reliable protection against high fault currents at 480VAC. The series' current-limiting, compact Class G dimensions prevent insertion into lower-voltage fuse holders, and fuse length varies by ampere rating so higher-rated fuses cannot be substituted into holders sized for lower ratings, supporting safe, code-compliant branch-circuit design across the full SLC lineup.

Key Features

• Ampere Rating Range: Available from 6A to 50A so installers can match actual equipment load requirements without greatly oversizing for harmless surges.
• Voltage Rating: 480VAC rating suited for industrial and commercial branch-circuit applications.
• Medium Time-Delay Opening: Medium-acting/medium time lag/medium time delay characteristic reduces downtime caused by power surges or equipment inrush demands.
• High Interrupting Rating: 100,000 A.I.R. provides reliable interruption of overcurrents up to 100,000 amperes at 480VAC.
• Current-Limiting Design: Current-limiting construction reduces equipment damage caused by the heating and magnetic effects of short-circuit currents.
• Compact Class G Construction: Unique SLC series dimensions prevent insertion of lower-voltage fuses into Class G fuse holders, and fuse length varies by ampere rating to prevent insertion of higher ampere-rated fuses into holders designed for lower ratings.
• Package Size: Industrial Cartridge construction sized for standard Class G fuse holders.
