SZW26-20/D202.2OM Three-Position Double-Pole Changeover Switch: This product is a three-position (1-0-2) double-pole changeover switch, featuring a panel-less, two-hole mounting structure. It has a rated current of 20A and is suitable for AC 50/60Hz circuits with a rated voltage of ≤440V and an insulation voltage of 690V.
Key Features:
Double-pole design allows simultaneous switching of both the live (L) and neutral (N) lines.
Rotating the handle to position "1" connects the first set of L and N lines; rotating to position "2" connects the second set of L and N lines; position "0" is the fully disconnected state, used for isolation.
Structure and Parameters:
Features a flame-retardant casing, silver alloy contacts, and thickened copper conductors for safety and durability.
Mechanical life ≥10⁵ cycles, electrical life ≥3×10⁴ cycles (operating frequency 120 times/hour).
Operating ambient temperature: -25℃ ~ +40℃.
Application Scenarios:
Suitable for distribution boxes, control cabinets, and other applications, for safe switching and isolation control between two sets of loads (such as dual power supplies, backup equipment), especially suitable for applications requiring simultaneous switching of both live and neutral lines.
