Un claro aparamenta de media tensión la decisión comienza con el diseño de red aprobado, no con una especificación de catálogo aislada. Esta guía mantiene el artículo centrado en las preguntas del proyecto que determinan un alcance viable y dirige las decisiones más específicas a artículos técnicos relacionados.
Medium-voltage switchgear is an assembly that switches, protects, isolates, and controls circuits above low-voltage distribution levels. Selection starts with the system voltage, earthing method, continuous current, prospective short-circuit current, feeder roles, and operating philosophy. A voltage label alone does not establish the required assembly duty.
Typical sections combine busbars, circuit breakers or load-break switches, disconnecting and earthing functions, instrument transformers, protection relays, cable compartments, and interlocks. Their ratings and clearances must be coordinated. The equipment schedule should state what is included in each incomer, feeder, bus section, and metering panel.
Air-insulated, gas-insulated, and metal-clad designs solve different footprint, environmental, and maintenance problems. Indoor rooms require attention to access, cable routing, ventilation, and safety clearances. Outdoor or compact installations add enclosure and environmental considerations. Confirm the actual construction in approved drawings rather than inferring it from a generic category name.
Relays, CTs, VTs, breaker operating times, and the protection philosophy must be aligned with the network study. Protection settings are not universal values that can be copied between projects. Coordinate them with upstream utility equipment and downstream transformers or feeders before commissioning.
Ask for approved GA drawings, wiring diagrams, nameplate information, routine-test records, relay documentation, and operation instructions. Factory tests should be witnessed or reviewed according to the contract. Site commissioning then verifies cable identification, interlocks, earthing, protection logic, and the latest settings file.
For 12kV or 24kV project discussions, the published Aparamenta de media tensión KYN28-12 can provide a catalog starting point. Product recommendation boundary: fault duty, internal-arc requirements, relay scheme, and utility interfaces must be confirmed by project engineering.

It switches, protects, isolates, and controls medium-voltage circuits according to the system design.
Provide voltage, current, fault duty, insulation level, feeder schedule, protection requirements, site conditions, and required documentation.
Compare footprint, environment, maintenance approach, project standards, and the required electrical duty rather than choosing by label alone.
They support safe operating sequences, but the required interlock scheme must match the approved single-line diagram and operating procedure.
Use the approved drawings, test records, relay settings, cable schedule, manuals, and commissioning procedure.
Use the network layout, feeder functions, protection needs, and site constraints to determine whether an RMU is appropriate.
