The **SVB-EZ-R/K** is a specific electronic safety component, typically identified as a **Main Switch Assembly** or **Emergency Stop Disconnect** manufactured by **Eaton (Moeller)**. It is widely used in industrial automation to ensure the safe disconnection of power to machinery. Below is a breakdown of its electronic and mechanical specifications. --- ### 1. Component Overview The SVB-EZ-R/K is an operator kit used for **T0, T3, and P1 series** rotary switch disconnectors. It functions as the interface between the human operator and the internal electrical contacts. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Eaton (formerly Moeller) | | **Part Type** | Rotary Handle / Main Switch Assembly | | **Colors** | Red handle on a Yellow locking ring (Standard for Emergency Stop) | | **Protection Rating** | IP65 (Dust-tight and protected against water jets) | | **Locking Mechanism** | Padlockable in the "OFF" position (up to 3 padlocks) | --- ### 2. Key Electronic Functions The "Electronic" aspect of this part refers to its role within a circuit interruption system: * **Safety Disconnection:** It serves as a "Main Switch" (Master Disconnect). When turned to the OFF position, it physically separates the internal copper contacts to ensure zero voltage in the downstream circuit. * **Emergency Stop Integration:** Because it features a Red/Yellow color scheme, it meets international standards (IEC/EN 60204-1) for emergency power-off devices. * **Load Break Capacity:** While the handle is mechanical, it is designed to actuate switches capable of breaking high inductive loads (AC-23A ratings) without electrical arcing damage. --- ### 3. Technical Specifications Table | Category | Details | | :--- | :--- | | **Mounting Type** | Front mounting (EZ = Center mounting/Rear mounting variants) | | **Switching Angle** | 90 degrees | | **Compatibility** | P1-25, P1-32, T0-1, T0-2, T0-3, T0-4, T3-1...T3-4 | | **Ambient Temp** | -25°C to +50°C | | **Standard Compliance** | IEC/EN 60947, VDE 0660, CSA, UL | --- ### 4. Components Included in the Kit 1. **Rotary Handle:** The ergonomic red lever used to toggle the switch. 2. **Yellow Locking Ring:** The circular base that indicates the "ON/OFF" status. 3. **Drive Shaft/Coupling:** Connects the external handle to the internal electrical switch block inside the cabinet. 4. **Hardware:** Screws and gaskets required to maintain the IP65 seal. ---
