SZW26-20/D202.2-B11R Rail-Mounted Three-Position Double-Pole Changeover Switch. This product is a three-position double-pole changeover switch, supporting 35mm standard DIN rail or 2-hole mounting for easy integration. Rated current is 20A, suitable for AC 50-60Hz/440V or DC 240V circuits.
Functions and Features:
Circuit Control: When the handle is rotated to the "1" position, circuits 1-2 and 5-6 are connected; when rotated to the "2" position, circuits 3-4 and 7-8 are connected; the "0" position disconnects all circuits, enabling switching between two loads.
Core Structure: Features a flame-retardant casing, silver alloy contacts, and thickened copper conductors to ensure reliable electrical connections.
Technical Parameters:
Mechanical Life: ≥10⁵ cycles
Electrical Life: ≥3×10⁴ cycles (operating frequency 120 times/hour)
Operating Environment: Temperature -25℃~+40℃, altitude ≤2000m
Main Application Scenarios:
Suitable for industrial control cabinets, distribution boxes, and automation equipment for dual power supply switching, load selection, or motor control. Rail-mounted installation is particularly suitable for applications requiring flexible layout and quick installation, such as PLC control cabinets and modular electrical systems.
