Condition
Used, good. Off-white NEMA 1 cabinet is clean with only minor scuffs and light dirt. Louvers clear; coils visible through the vents are intact with no discoloration or burn marks. Existing conduit nipple still attached on one side. Nameplate and barcode label pristine.
Before you orderA circular ink stamp on the unit reads 'RHM WSC 2010', which may be a test or inspection date — it is not a printed date of manufacture.
How we catalog
Every specification above is transcribed from this unit's own nameplate or data label. Nothing is inferred from a model number or copied from a manufacturer catalog. Where a plate was unreadable or absent, the field is left off rather than estimated. Equipment is sold as-is; we have not powered up or performance-tested these units unless stated. Inspection is welcome and encouraged before purchase.
