FAQs
This 70E-18/100A fuse uses ferrule-end terminations on both sides, enabling quick, vibration-resistant connections. Install in standard telecom panels with ferrule crimps or compatible ferrule-end fittings. Ensure correct orientation and seating, then verify continuity with a meter after mounting to prevent loose connections and reduce downtime.
The fuse is rated for 0.18 A (amperage), with an interrupt rating of 1 kAIC at 300 Vdc and a voltage rating of 125 Vac / 300 Vdc. This combination protects delicate telecom circuits from overcurrent conditions while allowing safe operation in mixed AC/DC environments common in data-path equipment.
Yes, the 70E-18/100A is CE marked, indicating compliance with European safety standards for telecom protection components. It supports European deployments in standard panels and can be integrated into networks and data paths where CE conformity is a requirement.
This fuse is ideal for protecting telecom and data-path circuits in networking gear, switches, and controller panels. Its small form factor, yellow color code, and ferrule-end terminations make it a practical fit for dense rack installations and field service where fast identification and quick replacement are valuable.
The non-indicating design reduces panel clutter and procurement complexity, while the color code aids rapid identification during maintenance. The 1 kAIC interruption and compact 70 Series design minimize downtime and spare-part variety, delivering predictable maintenance intervals and improved overall equipment reliability.
