Bussmann NTN-R-30 Dummy Fuse

Overview

The Bussmann NTN-R-30 Dummy Fuse is a non-conductive placeholder device designed to safely occupy unused fuse sockets in electrical panels and circuits. This innovative solution prevents accidental insertion of live fuses, reduces debris accumulation, and maintains panel integrity while ensuring compliance with safety standards. Note: This is a non-functional dummy unit—it provides no overcurrent protection.

Key Features

• Safety Assurance: Blocks access to unused fuse holders, eliminating risks of incorrect fuse installation.
• Non-Conductive Design: Crafted from insulating materials with 0A current rating; will not complete electrical circuits.
• Secure Fit: Engineered to snap seamlessly into standard NT fuse holders (30mm length, 10.3mm diameter).
• Visual Clarity: Bright red casing with “DUMMY” labeling ensures instant identification by technicians.
• Environmentally Resilient: Resists dust, moisture, and vibrations in industrial settings (operating temp: -40°C to 100°C).

Applications

• Filling vacant slots in power distribution panels
• Control cabinets for machinery/automation systems
• Automotive fuse boxes and electrical enclosures
• Training environments for safe circuit demonstration
