Description
To air condition an open area from the ceiling: Mitsubishi Electric cassette PLA-SM125EA + PUZ-SM125YKA with a nominal cooling capacity of 10,406 frigories/h (12.1 kW). It is an alternative to consider when there is a false ceiling and you want to free up the walls; it does not replace several splits for closed rooms. Check height, installation space, and air distribution. Installation is separate.
Before choosing it, it is advisable to check the available height above the ceiling and the location of the equipment. The panel and the control are part of the configuration: in "What is included" you can see which ones are supplied with this reference.

Questions about PLA-SM125EA + PUZ-SM125YKA
How many frigories does this cassette have?
The Mitsubishi Electric PLA-SM125EA + PUZ-SM125YKA set has a nominal cooling capacity of 10,406 frigories/h (12.1 kW). The power refers to the complete set, not to each air outlet of the cassette.
Is a cassette better than a wall-mounted split for my living room or premises?
This cassette is an option if the space and the false ceiling allow for the installation of PLA-SM125EA and proper air distribution. It offers 12.1 kW nominal cooling; it is not inherently better than a wall-mounted unit. To choose, compare the thermal load, height, position of people, and installation cost.
Does it cool several closed rooms?
It should not be chosen for that reason alone just because it has 10,406 frigories/h. An interior cassette distributes air in the area where it is installed; doors and partitions limit access to other rooms. For closed spaces, consider a multisplit or a duct network designed for them.
What should I check if the space receives a lot of sunlight?
Look at the square meters of the space, the large windows, and the hours of sunlight. If the premises or living room overheats and more capacity is needed, compare the Mitsubishi Electric PLA-SM140EA + PUZ-SM140YKAIt goes from about 10,406 to 11,524 frigories/h. Before deciding, we will review with you the power and the available space in the false ceiling.
What does PLA-SM125EA + PUZ-SM125YKA include?
1 × PLA-SM125EA (indoor unit); 1 × PUZ-SM125YKA (outdoor unit); 1 × Model to be confirmed (remote control). The previous composition identifies the units and controls of this offer. The installation is contracted separately.
What measurements should I check before booking the equipment?
Indoor Unit – Dimensions width x height x depth (Panel): 298 x 840 x 840 (40 x 950 x 950) mm. Outdoor Unit – Dimensions width x height x depth: 981 x 1,050 x 330 (+40) mm. These are the measurements of the indicated components, not the minimum installation space. Also allow for the clearances, connections, and maintenance access required by the manual.
What efficiency does this combination have and what can I compare?
SEER of the set · catalog June 2025: 5.5. SCOP of the set · average climate: 3.9. Compare the same magnitude, combination, and test climate. This data does not certify the consumption of your home nor the performance of another combination.
Is Wi-Fi included or is an accessory required?
Wi-Fi is not included in this offer. Mobile control requires a compatible accessory; its reference must be verified for the specific equipment.
What command does the equipment receive?
Remote control included. A specific remote control model is not assigned without confirmation in the supply.
Are the decibels in the technical sheet the noise I will hear at home?
Indoor Unit – Sound power: 65 dB(A). Outdoor Unit – Sound power: 72 dB(A). Maintain the indicated speed and mode when comparing. Pressure and sound power are different magnitudes; the perceived noise also depends on the room and the installation.
Is it suitable for an open office with many workstations?
It can fit if the calculation of the open area requires 12.1 kW. It is advisable to consider occupied workstations, computer equipment, and windows, and to position the unit so that the air is not directed uncomfortably over the tables. Closed offices require studying their own layout.
What changes compared to the 100 YKA if they fit in the same space?
The inner body measures 298 × 840 × 840 mm, but the cooling capacity increases from 9.5 to 12.1 kW. The exterior also changes along with the air flow. For a replacement, it is not enough to check the space: it is necessary to review the power supply, pipes, drainage, and the requirements of the room.
What power supply does this version require?
The PLA-SM125EA + PUZ-SM125YKA pair requires 400 V three-phase. The official sheet indicates 400/3 – 12.2 V/F – A. Before ordering it, your installer must check the line, the protections, and the available power supply; the single-phase VKA variant is not electrically equivalent.
Why doesn't the energy label appear on small splits?
This pair has a nominal power of 12.1 kW in cold and exceeds the 12 kW of that label's scope. In the technical sheet, you can check the indices and consumption from the Spanish catalog of June 2025. This edition is identified because the previous web table presents the seasonal data in a different format; we do not convert percentages by assumption nor do we draw a class of the scale for equipment up to 12 kW.
Can it air condition several closed rooms?
This 125 has a single internal cassette. It distributes air in the area where it is installed, but it does not allow for independent temperature selection for rooms separated by doors. If your premises have offices or private rooms, check with the installer if you need more units or a zoned distribution.
What should I consider for drainage and winter use?
PLA-SM125EA includes a drainage pump, but the installation requires a well-executed and tested drain. If you want to use it in cold conditions when the outside temperature drops below −5 °C, the documentation requires an optional wind protection guide; the published range does not mean that this accessory is included.
