The SZL9-75/D0723.3 has a rated current of 75A and features a three-position, three-pole structure. It has a rated current of 75A, with one power input split into two power outputs to supply two devices. When the handle is rotated to position 1, the first set of ABC contacts is connected; when rotated to position 2, the second set of ABC contacts is connected; and in the middle position 0, all contacts are disconnected. Different operating modes can be achieved through various contact combinations. The product design emphasizes operational stability and practicality, making it suitable for use in conventional electrical environments.
It is compatible with 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, good insulation, silver alloy contacts, thickened copper components for stable conductivity and long lifespan, flexible installation options, and customizable panel text. These features meet the daily operational needs of equipment and are suitable for use in 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 transfer switches. Mechanical life: 0.3 x 10⁶ cycles, operating frequency: 120 cycles/hour.
Electrical life: 0.6 x 10⁶ cycles, operating frequency: 120 cycles/hour.
