The **F2TS-43-R** is a specific model of a **Fused Terminal Block**, commonly used in industrial electrical panels for circuit protection and power distribution. It is designed to combine the functionality of a terminal connection point with an integrated safety fuse. --- ### Technical Specifications Below are the typical electronic and mechanical characteristics of the F2TS-43-R: | Feature | Specification | | :--- | :--- | | **Component Type** | Fused Terminal Block | | **Mounting Type** | DIN Rail (Standard 35mm) | | **Fuse Compatibility** | 5 x 20 mm Glass/Ceramic Fuses | | **Current Rating** | Up to 10A (Depending on fuse installed) | | **Voltage Rating** | 250V - 600V (Application dependent) | | **Wire Size Range** | 22 AWG to 12 AWG | | **Termination Method** | Screw Clamp | --- ### Key Electronic Components & Features #### 1. The Fuse Holder The core electronic feature is the integrated housing for a **5x20mm fuse**. This acts as the sacrificial link in the circuit. If the current exceeds the fuse's rating, the internal wire melts, breaking the circuit to protect sensitive downstream components like PLCs or sensors. #### 2. Screw Clamp Terminals The part utilizes high-conductivity copper alloy clamps. These ensure low contact resistance and prevent "hot spots" that could lead to electrical fires in high-vibration industrial environments. #### 3. Insulation Housing Constructed from high-grade **Polyamide (PA 6.6)**. This material provides: * **Dielectric Strength:** Prevents arcing between adjacent terminals. * **Flammability Rating:** Usually UL94V-0 (Self-extinguishing). #### 4. Optional LED Indicator (Model Variant Dependent) Many versions of the "F2TS" series include a built-in **blown-fuse indicator**. * **Circuitry:** A high-value resistor and a neon lamp (or LED) are connected in parallel with the fuse. * **Function:** When the fuse is intact, current takes the path of least resistance through the fuse. When the fuse blows, current flows through the indicator light, causing it to glow and signal a fault. --- ### Application Usage The F2TS-43-R is primarily used in: * **Control Panels:** To isolate individual control loops. * **Power Distribution:** Providing short-circuit protection for specific branches. * **Safety Interlocks:** Ensuring that a failure in one sensor does not shut down the entire system.
