- Thermally conductive foil: A material that efficiently transfers heat away from sensitive electronic components to heat sinks or the environment.
- Thermistor overload relay EMT6: A type of overload protection device using thermistors (temperature-dependent resistors) for monitoring motor heating and triggering disconnection if critical temperatures are reached.
- Three-phase asynchronous motor: A widely used motor that operates on a three-phase AC supply, where the rotor runs at a slightly slower speed than the magnetic field (non-synchronous).
- Three-phase current slip-ring motor: A motor using slip rings to allow external resistance to be inserted in the rotor circuit, improving starting torque and control.

- Time selectivity circuit-breaker: A circuit breaker designed to trip based on predefined time-current characteristics to coordinate with other protection devices downstream.
- Time-discriminating network topology: A system design that uses selective time delays to ensure only the faulty section of a network is disconnected during a disturbance.
- Timing relays: Devices that delay opening or closing of contacts for a defined time period, used in automation and sequencing applications.
- Top of ramp: The point in a ramp-shaped signal or voltage profile where maximum amplitude is reached before maintaining or returning to a lower level.
- Touch display: A display panel with integrated touch sensitivity, allowing user input directly via fingers or a stylus.
- Touch technology: The specific hardware and sensing method used in touchscreens, such as resistive, capacitive, or infrared.
- Transformer-protective circuit-breaker: A breaker designed to protect transformers from overcurrent and short-circuit conditions.
- Transistor: A semiconductor device used to amplify or switch electronic signals and electrical power.
- Trip blocks: Add-on modules to circuit breakers that determine tripping characteristics such as delay, sensitivity, and coordination.
- Trip-indicating auxiliary contact: A contact that signals the tripped status of a circuit breaker, used in control circuits for alarms or remote indication.
- Trip-indicating auxiliary contacts (mesh network): Contacts used in networked systems to report trip status digitally for advanced diagnostics and automation.
- Trip-indicating auxiliary contacts (motor-protective CBs): Used in motor-protection breakers to signal when the unit has tripped due to overload or short circuit.
- Tripping characteristics (overload relays): The predefined response behavior of a relay to overcurrent, including the delay before activation based on current magnitude.
- Tripping class: Defines how fast an overload relay reacts, typically based on time-to-trip at a given multiple of rated current (e.g., Class 10, 20, 30).
- Tripping classes CLASS: Standardized classifications that help match motor and overload protection characteristics.
- Type 1 coordination: Coordination between protection devices where damage to the contactor is acceptable and the system must be repaired after a fault.
- Type 2 coordination: Coordination ensuring that the contactor can be put back into service after a short circuit without damage.
- Type abbreviation, cables: Short codes used to indicate the structure, insulation, and usage type of electrical cables.
- Types of coordination (motor protection): Classifications defining how protection devices interact during a fault to ensure safety and minimize damage.
- Types of coordination (soft starter): Defines coordination between a soft starter and protection devices, especially under fault conditions.
- Types of protection: Refers to different protection schemes for electrical equipment, such as IP ratings, overcurrent protection, and thermal protection.
