- Heat sink: A passive component that dissipates heat away from electronic devices such as relays, drives, or power modules, helping maintain safe operating temperatures and prolonging lifespan.
- Heater switches: Switches designed specifically to control electrical heaters, often able to handle high current loads and temperature-related cycling.
- Heavy starting duty: A classification for motors or equipment that must start under high load conditions or with frequent start-stop cycles, requiring robust thermal and electrical protection.
- HMI–PLC: A combined Human-Machine Interface (HMI) and Programmable Logic Controller (PLC), integrating user control and programmable logic into a single device for efficient automation and control.
- Housing: The external enclosure of electrical components, providing physical protection, insulation, and sometimes environmental sealing (e.g., dustproof, waterproof).
