The SZW26-20 D202.2Y-D11 is a three-position single-pole padlock-type changeover switch with a "1-0-2" three-position structure and a rated current of 20A. It is suitable for AC 50-60Hz/440V or DC 240V circuits, enabling the switching of a single power source between two loads, with the middle "0" position serving as a safety disconnect point.
Safety and Structural Features:
Safety Locking Function: Comes standard with two padlocks, allowing the key to be removed and locked in the "0" position (or other positions as required), effectively preventing unauthorized or accidental operation, meeting equipment maintenance, isolation, and safety management requirements.
Installation Method: Four-hole robust mounting for stable and reliable structure.
Electrical Materials: Features a flame-retardant casing, silver alloy contacts, and thickened copper conductors for stable conductivity, safety, and durability.
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 applications requiring mandatory safety isolation and access control, such as: power switching and maintenance isolation in industrial distribution cabinets and control cabinets; Lockout/Tagout (LOTO) safety procedures during equipment maintenance; safe switching in test benches and motor control circuits;
Other critical control circuits where preventing accidental or unauthorized operation is required.
