Description
Panel Mount AC Inlet Power Socket with Integrated Fuse Holder (Model: IN3)
Product Overview
The IN3 Panel Mount AC Inlet Power Socket is a high-grade, commercial-ready electrical interface component engineered to serve as a fused primary alternating current (AC) entry point for electronics enclosures, heavy machinery, and industrial instrumentation panels. This specialized inlet seamlessly unifies a standard 3-pin grounded AC socket with an integrated, front-accessible safety fuse drawer. By incorporating overcurrent defense directly at the mains entrance, it removes the need for independent internal fuse blocks or messy in-line holders.
Molded from high-density, flame-retardant engineering thermoplastic, the IN3 features thick structural walls designed to absorb repeated insertion impacts. Equipped with premium copper-alloy solder lugs and a dedicated compartment for a standard 5mm x 20mm glass or ceramic cartridge fuse, this inlet guarantees low contact resistance and total hardware defense against unexpected current surges, short-circuits, and thermal runaway.
Key Features
-
Integrated Safety Fuse Drawer: Features an independent, front-facing bay designed to house a standard 5mm x 20mm overcurrent protection cartridge fuse, facilitating rapid diagnostic checks and toolless replacements.
-
Unified Heavy-Duty Architecture: Combines an AC socket, grounding chassis, and fuse circuit into a single, compact housing layout (Model: IN3), optimizing panel space inside crowded hardware builds.
-
Flame-Retardant Engineered Polymeric Shell: Molded from premium, non-conductive polymer that provides total high-voltage electrical isolation and strictly resists deformation under high continuous-load conditions.
-
High-Conductivity Copper Solder Tabs: Outfitted with robust, silver-plated rear metal pins that ensure rapid heat dissipation during manual soldering cycles and stable low-resistance operation.
-
Explicit Grounded Circuit Safety: Features clear internal terminal layouts for Phase/Line (L), Neutral (N), and a dedicated Safety Ground (E) pin to guarantee complete shock protection and safe chassis implementation.
