Koteloitu

Koteloitu is a Finnish adjective describing something that has been encased or housed in a protective shell or enclosure. It is formed from kotelo, meaning case or enclosure, with the participial suffix that yields a state of having been enclosed. The term is commonly used to indicate that an object or device is placed inside a protective housing rather than being exposed.

In practice, koteloitu is widely used in technology and industry. Typical contexts include koteloitu elektroniikkalaite (an electronic device in a housing), koteloitu valaisin (an enclosed light fixture), or koteloitu moottori (a motor contained within a casing). The adjective helps distinguish between components that are openly assembled and those that are protected by a housing.

Design and functional implications are central to the term. An enclosed, koteloitu design provides mechanical protection, dust and moisture resistance, and, in many cases, electromagnetic shielding. However, enclosure can influence heat dissipation, cooling, and accessibility for maintenance or repair, so designers balance protection with thermal and service considerations.

Related terms include kotelointi, the process of housing or enclosing equipment, and kotelo, the enclosure itself. The concept is common across engineering disciplines, electronics manufacturing, and product design, where specifying a device as koteloitu conveys its protected, housed state.
