The SZL9-50/D0723.3 is a 50A, three-pole, three-position changeover switch, capable of simultaneously switching three circuits. It features a logical switching arrangement, dividing one power input into two power outputs for two devices. Position 1 connects the first set of A, B, and C terminals, position 2 connects the second set of A, B, and C terminals, and the middle position (0) disconnects all circuits. This facilitates switching between different operating states, such as equipment mode switching or power source selection. Its structural design emphasizes practicality and compatibility with various electrical devices.
It is suitable for AC 50Hz~60Hz electrical circuits with a rated operating voltage of ≤440V and a rated insulation voltage of 690V. It features flame-retardant and high-temperature resistant materials, excellent insulation, safety and durability, silver alloy contacts, thickened copper components, stable conductivity, long lifespan, flexible installation options, and customizable panel text. These features meet the needs of daily equipment operation and make it suitable for use in complete sets of electrical switchgear or for starting, speed control, and reversing of three-phase asynchronous motors, as well as for switching between main and auxiliary circuits. It can also be used for switching between main and auxiliary circuits in industrial automation equipment. It can completely replace other changeover switches.
