- Feedback Circuit: A control circuit that sends information from the output of a system back to its input, used to maintain stability or respond to changes in load or conditions.
- Feeder System MSFS: A modular feeder system (likely the Eaton MSFS series) designed for distributing power efficiently in control cabinets and industrial switchboards.
- First environment: A classification under EMC (electromagnetic compatibility) standards referring to environments like residential, commercial, or light industrial spaces with less electrical noise.
- Flashing: The repeated turning on and off of a light or signal, often used as a warning or indicator function in control panels and machinery.
- Fleeting contact: A momentary contact that closes or opens for a short duration.
- On de-energization: The contact activates briefly when the circuit is turned off.
- On energization: The contact activates briefly when the circuit is turned on.
- Fleeting pulse: A short-duration electrical signal used for triggering a single action, such as a pulse to latch or unlatch a relay or to step a counter.
- Float switch, general symbol: The standard schematic symbol representing a float switch, a device that uses a buoyant float to open or close a circuit based on liquid level.
- Floor-standing Distribution board: A power distribution panel designed to be installed on the floor, typically larger in size and used in industrial or commercial installations for housing breakers and protective devices.
- Formulae: Mathematical expressions and equations used in electrical engineering to calculate values such as current, voltage, power, resistance, and more.
- Free-wheel diode suppressor: A diode placed across a coil (e.g., in a relay or contactor) to allow current to circulate after the coil is switched off, preventing voltage spikes (also called flyback diode).
- Fuseless, Reversing contactor DIUL: A specific Eaton contactor type (DIUL series) that allows motor direction reversal without fuses, integrating protection and switching in a compact unit.
