Overview
The Bussmann CHCC1I is an industrial-grade Class CC fuse holder designed for 600V, 30A circuits. This modular DIN rail fuse holder combines compact size with visual fault indication, making it ideal for distributed circuit protection in control panels and electrical enclosures. The CHCC1I accommodates standard Class CC 10x38mm fuses with a 200,000A interrupt rating (IR), delivering reliable overcurrent and short-circuit protection in the smallest possible package.
Key Features
- 1-pole modular design for DIN rail mounting (35mm standard track)
