Overview

LG KSSCA301A is the complete 30,000 BTU (2.5 Ton) R32 single-zone 4-way ceiling cassette mini split heat pump system from LG's 4-Way Ceiling Cassette line: the KNSCB301A indoor unit and the KUSXA301A inverter outdoor unit, sold together as the matched, AHRI-rated pair. It is rated 25.0 SEER2, 15.20 EER2, 10.40 HSPF2, runs on 208-230/60/1 power (32 A MCA / 35 A MOP).

Capacity modulates across 12,000 / 30,000 / 36,000 Btu/h in cooling and 14,000 / 34,000 / 40,000 Btu/h in heating (min / rated / max), so the system idles at part load instead of cycling. Heating continues down to -13°F outdoor, with 36,200 Btu/h available at 17°F and 34,000 Btu/h at 5°F.

  • 1 × LG KNSCB301A 30,000 BTU 3×3 ceiling cassette indoor unit with Wireless Remote Controller PWLSSB21H
  • 1 × LG KUSXA301A R32 inverter heat pump outdoor unit

  • Interconnect cable, disconnect and breaker sized to the MCA/MOP in the specifications; pad or wall bracket; condensate drain
  • Requires PT-AAGW0 grille (sold separately)

Typical coverage is roughly 1,300–1,600 sq ft depending on climate, insulation and layout. AHRI reference 214825956 (Energy Star, Energy Star Cold Climate). Installation and warranty registration should be completed by a licensed contractor who has completed LG training; the LG limited warranty document is linked under Documentation.

Common Questions

What is included with the KSSCA301A system?

KSSCA301A ships as Includes KNSCB301A indoor unit and Includes KUSXA301A outdoor unit. Line set, interconnect wiring, disconnect, pad or bracket and condensate drain are field supplied.

What power does the KSSCA301A need?

208-230V, 1-phase. Minimum circuit ampacity and maximum overcurrent protection are listed in the Specifications table above and on the LG submittal under Documentation; size the breaker and wire to those values and local code.

Is the submittal sheet and installation manual available for KSSCA301A?

Yes — the LG submittal data sheet, engineering manual, installation manual and warranty document are all linked under Documentation on this page and can be downloaded without an account.

Is the stock number on this page real?

Yes — it's the live count from our own shelf, not an availability estimate. If it says 4, that's how many are physically here. When it hits zero, this page says so.

Is this a genuine LG unit, or aftermarket?

Genuine LG OEM equipment — not an aftermarket substitute.

I see this listed under a different name on other sites. Is it the same part?

Yes — manufacturers and distributors sometimes use different brand names or legacy labels for the same part number. Part number KSSCA301A is identical across all name variations.

What's the warranty on this part?

Warranty terms vary by manufacturer. Contact us with your order number for details specific to this part.

How fast does this ship?

In-stock items ship the same business day on orders placed before 1pm ET, Monday–Friday. Standard ground delivers to most of the continental US in 2–5 business days. This part ships by LTL freight, so transit runs on the freight schedule — we'll contact you to arrange delivery.

Does everything ship UPS or FedEx Ground?

This part ships by truck freight rather than parcel — still free, included in the price shown, and we'll contact you to schedule delivery before it ships.Most orders ship UPS or FedEx Ground. A small number of large or heavy parts across the catalog ship by truck freight instead — that's still free, and we reach out to arrange a delivery window before those orders leave the warehouse.
