UKP-250S03K 3-Pole 250A Side-Operated Switch Disconnector for Compact Switchgear Cabinets
The KRIPAL UKP-250S03K is a 3-pole, 250A AC switch-disconnector fitted with a side-mounted operating handle, designed for base/screw-mount installation in enclosures where side-access operation is preferred over front-panel handle placement.
This configuration is especially useful in deep cabinets, multi-tier switchgear assemblies, or layouts where the front face is reserved for metering, indicators, or other components. The 3-pole design isolates three-phase circuits with a robust, spring-driven quick-break action, backed by strong dielectric and short-time withstand performance for demanding industrial environments.
