Eaton Crouse-Hinds CHMM3 Mounting Adapter - IP66
Part Number: CHMM3
Quick Summary
CHMM3 is a mounting module adapter for VMVL/PVML fixtures that enables secure retrofit in hazardous locations. Engineers often face misalignment, material incompatibility, and retrofit downtime when upgrading older HazLux systems. This adapter delivers IP66 enclosure protection, NEMA 4X ruggedness, and NEC/CEC compliance for Class I, Division 2; Class II, Division 1; Class III. By using copper-free aluminum and a retrofit-ready design, it reduces weight, enhances corrosion resistance, and simplifies field installation, making VMV/VMVL mounting smarter and more reliable for industrial lighting upgrades. The result is faster installations, fewer field changes, and long-term performance in demanding environments.

IF 1917 - CHMM3 Top Hat Adapter
Eaton Specification Sheet - CHMM3
Copper-free aluminum construction provides superior corrosion resistance while reducing overall weight, delivering longer service life in harsh industrial environments and lowering maintenance frequency for HazLux retrofit projects. This translates to fewer unplanned outages and lower lifecycle costs, especially in outdoor, washdown, or chemically aggressive facilities where VMVL/ PVML adapters operate. The CHMM3 design supports efficient field retrofits, enabling quick alignment and secure mounting for VMVL/PVML configurations and helping sustain production with minimal downtime. Pairing robust material with a retrofit-ready form factor improves installation confidence and reduces the need for custom hardware or modifications during HazLux upgrades. In practice, contractors see faster commissioning and clearer compliance pathways when upgrading legacy lighting to modern Champ VMV solutions.

FAQs
To install CHMM3, verify VMVL/PVML compatibility and HazLux retrofit suitability, then align the adapter with the fixture mounting surface and secure using standard hardware per the IF 1917 instructions. Ensure an IP66 seal and verify enclosure integrity after installation. Refer to the CHMM3 installation sheet for torque specs and step-by-step guidance to minimize field downtime.
CHMM3 provides IP66 enclosure protection and a NEMA 4X rating, designed for hazardous/classified locations. It supports NEC/CEC compliance with classifications including Class I, Division 2; Class II, Division 1; and Class III, making it suitable for a range of hazardous-area installations and ensuring regulatory alignment during retrofits.
Yes. CHMM3 is specifically engineered to retrofit Thomas and Betts HazLux fixtures, delivering a copper-free aluminum mounting solution with VMVL/PVML compatibility. It streamlines installation, reduces need for fabrications, and provides a durable, compliant interface for hazardous-location lighting upgrades.
CHMM3 measures 13.52 inches in length, 12 inches in width, and 2.5 inches in height, with a weight of 2.2 pounds. These dimensions support straightforward mounting within standard HazLux retrofit footprints, ease handling in the field, and compatibility with common mounting rails and enclosures found in industrial facilities.
The copper-free aluminum construction resists corrosion, reducing maintenance needs and replacement costs in harsh environments. Improved durability and faster retrofits lower total cost of ownership, while IP66/NEMA 4X protection minimizes enclosure-related maintenance and downtime, delivering a favorable return on investment for long-term hazardous-location lighting projects.
