The SZW26-63/D202.2 is a three-position (1-0-2) changeover switch with a rated current of 63A, designed for manual switching and isolation between two independent high-current circuits. In position "1," it connects the first output circuit (contacts 1-2, 5-6); in position "2," it connects the second output circuit (contacts 3-4, 7-8); the middle "0" position completely disconnects all contacts, providing a safe electrical isolation point. The product features silver alloy contacts and thickened copper components, with an insulation voltage of 690V, suitable for AC 440V/50-60Hz lines. It has a reliable structure, customizable panel markings, a mechanical life of 300,000 cycles, and an electrical life of 60,000 cycles.
It is suitable for industrial applications requiring manual switching or isolation of high-current power supplies and loads. Typical applications include: as a manual changeover switch for two 63A power sources (such as mains power/generator); controlling the "one-use, one-standby" switching of two high-power devices (such as motors, electric heating devices); or as a reliable maintenance isolation point in power distribution systems and large mechanical equipment. It is widely used in power, mining, transportation, and automation control fields.
