Overview
The Gould Shawmut 30321 is a 1-pole, 30-ampere, 600-volt AC/DC fuse block engineered for industrial electrical protection. This Class CC midget fuse block accommodates standard 1-1/2″ x 13/32″ midget fuses and is ideal for control panels, distribution systems, and equipment requiring reliable overcurrent protection. The unit features high-conductivity tin-plated copper alloy fuse clips for superior electrical continuity and corrosion resistance.
Key Features
