The Schneider Electric HMIZU50 is a gasket designed as a fixing accessory for the illuminated USB switch product line. Its sole function is to provide a seal between the switch bezel and the panel cut-out, keeping dust and moisture out of the enclosure opening.
As a simple molded rubber or silicone part, the HMIZU50 carries no electrical ratings, approvals, or compliance documentation beyond what the parent illuminated USB switch assembly requires. The buyer's fit check is purely mechanical: it must match the panel cut-out diameter and the switch bezel profile of the specific illuminated USB switch model it was sold with.
