Eaton Specification Sheet - CHMM4
Copper-free aluminum construction provides excellent corrosion resistance and a lighter overall assembly, reducing installation effort and logistics costs while extending service life in challenging environments. This translates to lower maintenance frequency and fewer replacement parts, a tangible total-cost-of-ownership improvement for facilities with outdoor or damp locations. IP66 and NEMA 4X ratings protect internal components from dust, water ingress, and corrosive elements, delivering reliable performance in wash-down zones and harsh industrial settings. For hazardous locations, the NEC/CEC classifications Class I Division 2, Class II Division 1, and Class III ensure compliance with regulatory requirements, enabling safe retrofits without extensive enclosure changes. The CHMM4 is designed to retrofit General Electric H2 Filtr-Gard fixtures, simplifying inventory management and accelerating project timelines by leveraging existing mounting footprints. With VMVL/VMV compatibility, installation aligns with current Champ-series infrastructure, reducing the need for rework and enabling faster commissioning. Documentation and installation resources further shorten field time, supporting technicians with clear, standards-driven guidance, warranty protection, and consistent performance across deployments.
