Overview

The Littelfuse H345601A ACS Shock-Safe 3AG Panel-Mount Fuse Holder (SKU: H345601A) is a high-integrity fuse holder designed to eliminate electrical shock hazards in compliance with IEC standards 60065 and 60127. This panel-mount device accommodates 3AG type fuses and integrates an anti-tease mechanism that prevents accidental circuit interruption when the knob is inadvertently depressed during operation or maintenance. This feature ensures continuous system functionality in critical applications. The ACS series offers five distinct fuse holder types, providing maximum flexibility for inventory reduction and application versatility. Users can select between two knob styles: a screwdriver slot for precise control or a finger-grip for easier manual operation. The screwdriver slot knob style includes a drip-proof option, making it suitable for environments where moisture ingress is a concern. Two terminal configurations are available to match application requirements: screw terminal for secure wire connections or wire leads for direct integration. The low-profile body design enhances safety by minimizing exposure to live components while maintaining ease of access for fuse replacement. This fuse holder is engineered for panel-mount installations in industrial control panels, power distribution systems, and machinery protection circuits where personnel safety and operational reliability are paramount. Key specifications include a 3AG fuse size compatibility, panel-mount design, and compliance with IEC shock-safety standards. The anti-tease feature and multiple configuration options make the H345601A an ideal solution for applications requiring both safety and operational flexibility in electrical protection systems.
