Eaton 281223 varistor-spanningsbegrenzer met LED voor DILM17-32 contactors, 240V AC

Electrical panel builders and maintenance technicians use the Eaton 281223 varistor suppressor module to protect DILM17, DILM25, and DILM32 contactors from voltage spikes. The module plugs directly into the contactor, providing overvoltage suppression and arc quenching for 240V AC coil circuits. An integrated LED gives immediate visual confirmation of suppressor status.
