The Hoffman ECL906050PB is a Comline OSP battery compartment enclosure constructed from aluminum with a light gray finish. It measures 1281 x 600 x 500 mm (50.43 x 23.62 x 19.69 inches). The unit features a solid wall-mount door and carries NEMA 3/3R/4/4X/12 and IP66 ratings, ensuring protection against environmental factors.
Verify the specific NEMA rating requirements against your installation environment before ordering. Confirm that the internal dimensions accommodate your specific battery bank size. Ensure the wall-mounting hardware is compatible with the enclosure's pre-drilled holes. Check local regulations regarding outdoor electrical enclosures.
Select this model when aluminum construction is required for weight or corrosion resistance compared to steel. The OSP package designation indicates suitability for outside plant conditions. Consider the IP66 rating if exposure to heavy rain or dust is expected. Verify that the 500mm depth provides sufficient space for cable management alongside batteries.
This part belongs to the nVent Hoffman Comline series, which specializes in outdoor and harsh-environment enclosures. The ECL prefix typically denotes a standard cabinet style within the Comline lineup. The PB suffix specifically identifies the inclusion of a battery compartment feature, distinguishing it from standard equipment cabinets.
Direct substitutes must match the 1281x600x500mm footprint and aluminum material. Verify that any replacement also includes the battery compartment configuration. Ensure the new unit maintains equivalent NEMA 4X/IP66 ratings for environmental sealing compatibility.
