The **SVB-ZE-R/CE** is a specialized electrical component produced by **Eaton (Moeller)**. It serves as a **rotary handle assembly** for main switch applications, specifically designed to be coupled with P1 and P3 series rotary switch disconnectors. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Eaton (formerly Moeller) | | **Part Type** | Rotary Handle / Door Interlock | | **Compatibility** | P1 & P3 Switch-Disconnectors | | **Color Scheme** | Red handle / Yellow locking ring (Emergency Stop) | | **Protection Rating** | IP65 (Dust-tight and water jet resistant) | | **Locking Mechanism** | Padlockable in the OFF (0) position | | **Application** | Emergency switching off / Main switch | --- ### 2. Core Electronic and Safety Features The SVB-ZE-R/CE is not a standalone active electronic device, but rather a **control interface** for power electronics. Its electronic significance lies in its safety certifications and circuit interruption role: #### A. Emergency Stop Functionality The red-yellow color coding indicates that this part is compliant with safety standards for **Emergency Stop** devices. When paired with a P1 or P3 switch, it provides a physical break in the circuit to immediately halt machinery. #### B. Door Interlock System This part is designed for **rear mounting** or cabinet door installation. * **Interlock:** It ensures the cabinet door cannot be opened while the switch is in the "ON" position. * **Safety Overrun:** It allows for the safe isolation of the internal circuitry before a technician gains access. #### C. Environmental Durability The unit is rated **IP65/NEMA 12**, meaning it protects the internal electrical contacts of the switch from: * Industrial oils and coolants. * Dust and metallic particles. * High-pressure water splashes. --- ### 3. Component Assembly Breakdown The part consists of the following sub-components required for the electrical interface: 1. **Rotary Handle:** The ergonomic red grip for manual operation. 2. **Locking Ring:** A yellow collar that can accommodate up to three padlocks for **LOTO (Lockout/Tagout)** procedures. 3. **Shaft/Coupling:** Connects the external handle to the internal switch body located on the DIN rail or backplate. 4. **Front Plate:** Labeled with "0" (OFF) and "I" (ON) markings for clear visual status. --- ### 4. Regulatory Standards The "CE" suffix confirms the component meets the following European directives: * **Low Voltage Directive (LVD)** * **Machinery Directive** (regarding Emergency Stop requirements) * **RoHS** (Restriction of Hazardous Substances)
