Description
To air condition an open area from the ceiling: Mitsubishi Electric cassette PLA-SM125EA + PUZ-SM125VKA 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 multiple splits for closed rooms. Check height, mounting space, and air distribution. Installation not included.
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-SM125VKA
How many frigories does this cassette have?
The Mitsubishi Electric PLA-SM125EA + PUZ-SM125VKA unit has a nominal cooling capacity of 10,406 frigories/h (12.1 kW). The power refers to the complete unit, 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-SM140VKAIt 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-SM125VKA include?
1 × PLA-SM125EA (indoor unit); 1 × PUZ-SM125VKA (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.
Can it fit in a restaurant dining room?
It is a candidate for an open table area whose thermal calculation matches 12.1 kW. It is necessary to consider diners, lighting, glass surfaces, and the renewal air. Kitchen extraction and ventilation are sized separately: this cassette provides climate control, but does not replace those systems.
I'm interested in the 125 or the 140 single-phase?
The 140 increases from 12.1 to 13.4 kW of cooling and from 27.2 to 30.7 A of maximum current. The 125 may be sufficient if the calculation supports it; it is not advisable to assume the higher consumption and electrical demand of the next size without first checking the needs.
What power supply does this version require?
The PLA-SM125EA + PUZ-SM125VKA pair requires 230 V single-phase. The official sheet indicates 230/1 – 27.2 V/F – A. Before ordering it, your installer must check the line, protections, and available power supply; the three-phase YKA 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.
