1PCS Two-Way Knife Switch (2P, 220V) Key benefits Reliable source switching: Double-throw reverse conversion lets you switch cleanly between two power sources (for example, grid and generator or inverter) without complex wiring changes. High load capacity: Rated to handle relatively high electrical loads with a 100A capacity, making it suitable for demanding household circuits. Safety isolation: Functions as an isolation switch to safely disconnect circuits during maintenance or in emergency conditions; particularly useful in photovoltaic installations. Stable connection: 2P two-phase design provides a stable, secure electrical connection for 220V household systems. Specifications (as provided) Voltage: 220V household Poles: 2P (two-phase) Capacity: 100A Function: Double-throw (reverse conversion) and isolation switch Model / color option: 2P 32A How it solves common problems Eliminates manual rewiring when changing power sources by providing a single, reliable switching mechanism. Reduces risk during maintenance or fault conditions by providing a clear isolation point. Supports higher-current household circuits that require robust switching components. Practical applications Home backup power: Switch between utility power and a generator or inverter during outages. Photovoltaic systems: Use as an isolation and switching device for solar inverters and arrays during installation, maintenance, or system changes. Electrical maintenance: Isolate circuits for safe inspection, repair, or replacement of downstream equipment. Installation and compatibility notes Designed for 220V household electrical systems and 2P two-phase wiring. Ensure the installed model and color option match your system requirements; consult the provided model designation (2P 32A) and the device’s 100A capacity to confirm suitability. Installation should be performed by a qualified electrician to ensure correct wiring, mounting, and compliance with local electrical codes. Performance and handling Built to provide stable, repeatable switching and isolation for household and small-scale PV applications. Intended for applications that require a robust mechanical switching solution and clear isolation of circuits. If any additional details (mounting dimensions, enclosure material, or certification) are required, consult the product datasheet or contact the supplier to confirm compatibility with your installation.
