ABB STOTZ-KONTAKT 3-Pole Load Disconnector 400V 100A E203/100R 2CDE283001R0100

When a main switch must reliably isolate a three-phase circuit up to 100 A, the ABB E203/100R provides a compact DIN-rail solution. This 3-pole load disconnector is built for manual switching under load and offers clear ON/OFF indication for safe maintenance.

Who is it for

Panel builders and electricians who need a robust main switch for distribution boards, motor feeders, or industrial control panels. Its 3-module width saves space without compromising performance.
