Manual dual power transfer switch 400VAC - 35mm DIN rail mounting, side locking, 3P 125A circuit breaker

Features:1.OVERLOAD AND SHORT-CIRCUIT PROTECTION: This dual-power manual transfer switch is equipped with overload and short-circuit protection, ensuring the safety of your electrical system.
2.One-sided locking for added safety: The right-side breaker handle is locked to the internal tripping mechanism of the left-side breaker.Therefore, opening the right-side breaker will trip the left-side breaker.When the right-side breaker is open, attempting to open the left-side breaker will fail, and the right-side breaker must be manually closed before the left-side breaker can be opened.
3.SAFE TO USE: When both handles are turned on simultaneously, only the right-side circuit is energized.The circuit breaker tripping mechanism on the left side is pre-disengaged, eliminating the risk of both circuits being energized simultaneously.
4.ROBUST CONSTRUCTION: The switch is constructed with silver alloy contacts for improved conductivity and a flame-retardant PC housing for added safety.
5.3-COLOR INDICATOR WINDOW: The switch features a three-color indicator window, with red indicating tripping, yellow indicating overload protection, and green indicating normal operation.
