Class G Fuses

Class G fuses are current-limiting, high-performance fuses (UL/CSA 248-5) for 600V AC/300V DC circuits. They feature a compact ⅜”” x 1½”” (10x38mm) design with 200kA interrupting rating, ideal for branch circuit protection in industrial and commercial systems.

Fuse Types Under Class G:
GMA – Fast-acting, general-purpose protection.
GMC – Time-delay for motor/transformer inrush tolerance.
GDL – Dual-element (time-delay + fast-acting).
