Category: Circuit Protection Devices, Electronics, Mersen

Overview

This datasheet presents information on the Amp-Trap CS-3 and 9F60/9F62 Series of medium voltage fuses designed for transformer protection by Mersen. These fuses offer a range of voltage ratings, specifically 2.75kV, 5.5kV, 8.25kV, 15.5kV, 25.8kV, and 38kV, and are ferrule mounted. The datasheet includes their applications, features, benefits, ratings, and approvals.

Applications

The fuses serve as protective devices for transformers or distribution systems ranging from 2.4kV to 34.5kV. They provide both overload and short circuit protection. The fuses are adept at handling transformer magnetizing inrush current and are current-limiting to ensure superior equipment protection.

Highlights and Approvals

These medium voltage fuses are E-Rated and UL listed for safe outdoor use. They have gained specific approvals, including some that are UL listed under standard File E143362.

Features/Benefits

The Amp-Trap CS-3 and 9F60/9F62 series boast several features beneficial to users:

Compatibility: Products are UL listed and compatible with other UL listed equipment.
Ferrule Mounting: Standardized ferrule mounting allows for ease of use with standard clips and interchangeability with different brands.
Current-Limiting Design: Ensures high levels of equipment protection
Non-Venting Operation: The fuses operate silently without venting.
Identification: Catalog numbers and manufacturing dates are metal embossed for durable identification.
