Overview

The Mersen GP30 (SKU: GP30) is a fast-acting midget plug fuse designed for reliable circuit protection in industrial and residential applications. This 1-1/2" x 13/32" (10 mm x 38 mm) fuse operates at a maximum of 125VAC and has a current rating of 30A. A key feature is its visual indicator, which clearly signals a blown fuse, simplifying troubleshooting and minimizing downtime. The GP30 is RoHS compliant and lead-free, operating effectively within a temperature range of -40°C to +85°C. It offers low Watts loss (3W or less) and a UL 94-V0 flammability rating. This fuse is ideal for supplemental protection of circuits where blown fuse indication is crucial, such as solenoid or control circuits. The GP30 is UL Listed to standard 248-14 (1/10 to 15A) and UL Recognized for 20-30A ratings. It provides dependable protection with clear operational feedback, ensuring operational continuity. Manufactured in the USA, the Mersen GP30 is a trusted choice for applications requiring fast-acting, visually indicated fuse protection.
