Feature:1. PROTECTION FUNCTION: The dual power manual transfer switch is designed for switching between two power sources and provides overload and short circuit protection.2. SIDE INTERLOCK: The handle of the right breaker is interlocked with the internal release mechanism of the left breaker. Therefore, opening the right breaker will cause the left breaker to trip. When the right breaker is open, opening the left breaker will fail, and the right breaker must be manually closed before the left breaker can be opened.3. SAFE USAGE: When both handles are simultaneously opened, only the right circuit is energized and the release mechanism of the left breaker is already disconnected, ensuring there is no danger of both circuits being energized simultaneously.4. FINE WORKMANSHIP: The switch features silver alloy contacts and a PC flame retardant material casing. It also has a three color indicator window, red (tripped), yellow (overload protection), and green (normal operation).5. WIDE APPLICATION: The switch is suitable for use in recreational vehicles, homes, generators, or other dual power systems. It can be easily installed using screw clamp connections and 35mm DIN rails.Specification:Item Type: Dual Power Manual Transfer SwitchMaterial: PC Flame Retardant, SilverRated Voltage: 230VACCurrent: 63ARated Frequency: 50 60HZPoles: 2PShort Circuit Breaking Capacity: 3000AShort Time Withstand Current: 1500A/1sElectrical Life: >1500 timesMechanical Life: >8500 timesProtection Level: IP20Operating Temperature: -5 to 40Terminal Cable Size: 16mmInstallation: 35mm DIN RailThree Indicators: Red (Tripped), Yellow (Overload Protection), Green (Normal Operation).Package List:1 x Dual Power Transfer Switch
