The **WSBS-11A-R** is a specific electronic component typically manufactured by **Schurter**. It belongs to the category of high-performance **switch and socket-outlet combinations**, specifically designed for power distribution and circuit protection in industrial and medical equipment. --- ## 1. Core Technical Specifications The WSBS-11A-R is primarily a power entry module that integrates several functions into a single housing. | Feature | Specification | | :--- | :--- | | **Component Type** | Power Entry Module (PEM) | | **Mounting Type** | Snap-in (Front Side) | | **Rated Current** | 10A - 15A (Depending on region/standard) | | **Rated Voltage** | 250 VAC | | **Circuit Breaker** | Integrated Thermal (TA45 series) | | **Termination** | Quick-connect terminals (6.3 x 0.8 mm) | | **Protection Class** | Class I (IEC 61140) | --- ## 2. Key Electronic Functions ### A. Integrated Circuit Protection The "11A" in the series often refers to the inclusion of a **TA45 Thermal Circuit Breaker**. Unlike a standard fuse, this is a resettable protection device that: * Trips during an overcurrent event. * Functions as the primary ON/OFF power switch. * Protects the internal circuitry of the device from short circuits or thermal overload. ### B. Power Connection (IEC C14) It features a standard **IEC 60320-1 / C14 inlet**, which is the universal connector for power cables used in desktop computers, medical monitors, and laboratory equipment. ### C. Mechanical Switching The rocker switch is designed for high inrush currents, preventing the contacts from welding together when the device is first powered on (a common issue with capacitive loads). --- ## 3. Applications and Usage Due to its robust design and international safety approvals (UL, VDE, CSA), the WSBS-11A-R is used in: 1. **Medical Equipment:** High reliability and specific leakage current standards. 2. **Laboratory Instruments:** Precise power control for sensitive measurement tools. 3. **Industrial Automation:** Durable power entry for control panels. 4. **Audio/Video Gear:** High-quality power distribution for rack-mounted systems. --- ## 4.
