The **SVB-KZ-R/CE** is a specialized electronic component, typically categorized as a **Main Switch Assembly** or **Emergency Stop Switch** used in industrial automation and motor control systems. It is primarily manufactured by brands like **Eaton (Moeller)**. --- ### 1. Technical Specifications The device is designed as a rotary handle kit for circuit breakers and switch-disconnectors. Below are the core technical attributes: | Parameter | Specification | | :--- | :--- | | **Component Type** | Rotary Handle (Lockable) | | **Safety Standard** | CE (Conformité Européenne) | | **Degree of Protection** | IP65 (Dust-tight and protected against water jets) | | **Color Coding** | Red handle / Yellow locking ring (Safety/Emergency) | | **Locking Mechanism** | Padlockable in the "OFF" position (up to 3 padlocks) | | **Application** | Emergency-Stop / Main Switch functions | --- ### 2. Electronic & Mechanical Functions While the SVB-KZ-R/CE is a mechanical interface, it performs critical roles in an electronic control circuit: * **Circuit Interruption:** It provides the physical interface to actuate a switch-disconnector (like the P1 or P3 series), which electronically isolates a motor or machine from the power source. * **Forced Opening:** It ensures that contacts are physically separated, a requirement for safety-rated electronic disconnects. * **Position Feedback:** Often paired with auxiliary contacts (e.g., NO/NC blocks) to send an electronic signal to a PLC (Programmable Logic Controller) indicating the switch status. --- ### 3. Usage Context This part is commonly found in the following electronic environments: 1. **Industrial Control Panels:** Acts as the primary power cutoff on the exterior of a metal enclosure. 2. **Motor Control Centers (MCC):** Used to isolate specific heavy-duty motors during maintenance. 3. **Safety Logic Circuits:** Integrated into E-Stop loops to ensure the system cannot be restarted while the handle is locked in the "OFF" position. --- ### 4. Installation Example ```yaml Component: SVB-KZ-R/CE Compatibility: Eaton P1-25, P1-32, P3-63 Switch-disconnectors Mounting: Front mounting (flush or surface) Shaft Type: Direct or extension shaft connectivity ```
