230VAC 63A Dual Power Manual Transfer Switch 35mm DIN Rail Mount Single Side Interlock Circuit Breaker 2P f26 1PROTECTION FUNCTION: The dual power manual transfer switch is designed for switching between two power sources and provides overload and short circuit protection. 2SIDE 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. 3SAFE 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. 4FINE 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). 5WIDE 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.
