Overview
The Gould Shawmut 30320 is a compact, open-style fuse block rated for 30 amperes at 600 volts AC/DC. Built for Class CC and midget fuse applications, this adder-block design allows stacking onto 1-pole, 2-pole, or 3-pole configurations to create segmented multi-pole assemblies. Engineered for industrial control panels, distribution cabinets, and power protection circuits, the 30320 delivers consistent overcurrent protection with minimal footprint.
Key Features
- 30 ampere, 600 volt AC/DC rating with 200,000 amp RMS symmetrical interrupting rating
