Product Overview

The 0242.100UR is a 242 Series Barrier Network Fuse designed for potentially explosive environments, with a rated current of 0.100A and intrinsic safety compliance. It effectively protects electronic equipment from overloads and short circuits, ensuring stable operation in hazardous scenarios such as oil, chemical, and mining industries. Its high interrupting capability and rugged environmental performance make it a core safety component for explosion-proof electrical systems.

Key Features

• High Safety-Rated Protection: Offers a 4000A@250VAC/VDC interrupting capacity, quickly cutting off overload currents to safeguard intrinsic safety equipment.
• Dual Mounting Flexibility: Supports both axial lead and surface mount options, adapting to various circuit layouts.
• Eco-Compliant Design: Lead-free, halogen-free, and RoHS compliant, meeting global green manufacturing standards.
• Wide Temperature & Impact Resistance: Operates from -40°C to 125°C, with resistance to thermal shock and vibration for harsh industrial environments.
• Precision Overload Response: Trips within 10 seconds at 300% overload and 0.002 seconds at 1000% overload, minimizing fault impact.
