HPS 25 kVA Single-Phase Dry-Type Transformer
HPS 164855 25 kVA Single-Phase Dry-Type Transformer — 600 V Primary / 120-0-120 V Secondary — CAT P/N 471-4093
Description
Available is one Hammond Power Solutions (HPS) 164855 single-phase dry-type transformer, rated 25 kVA, 60 Hz, with a 600 V primary and 120-0-120 V secondary. The nameplate identifies primary terminals H1–H2 and secondary terminals X2–X0–X1. It also shows primary-voltage taps at 630, 615, 600, 585, and 570 V.
The HPS nameplate carries a supplemental P/N 4714093 marking, and the matching Caterpillar crate label identifies CAT P/N 471-4093 as a transformer. The CAT number is therefore retained as a buyer-facing package/OEM reference, while HPS is identified as the physical manufacturer and HPS P/N 164855 is the manufacturer part number.
HPS describes its general-purpose distribution transformers as low-voltage products rated 600 V and below for supplying appliance, lighting, heating, motorized-machine, and power loads from electrical distribution systems. The offered unit’s exact ratings, configuration, and suitability are governed by its own physical nameplate and must be verified by the buyer.
