The SZL9-50/D1050.4 features a four-section, three-position structure with a rated current of 50A, suitable for multi-circuit electrical control applications. Through position switching, one power input is divided into two power outputs, supplying two devices. Position 1 connects the first set of ABCN terminals, position 2 connects the second set of ABCN terminals, and the middle position 0 disconnects all connections. This allows for the adjustment of multiple circuit combinations. The product can be installed in distribution boxes or control devices for circuit management and status switching. The operation is clear and straightforward, making it suitable for systems requiring centralized control of multiple circuits.
It is compatible with AC 50Hz~60Hz electrical circuits with a rated operating voltage ≤440V and a rated insulation voltage of 690V.
It uses flame-retardant and high-temperature-resistant materials, offering good insulation, safety, and durability. Silver alloy contacts and thickened copper components ensure stable conductivity and a long service life. Flexible installation methods and customizable panel text are also features. It meets the daily operational needs of equipment and can be used in complete sets of electrical switchgear or for starting, speed control, and reversing of three-phase asynchronous motor loads, as well as for switching between main and auxiliary circuits. 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.
