List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Quite Universal Circuit Simulator (Qucs) is a free-software electronics circuit simulator software application released under GPL. It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit.
CircuitMaker is electronic design automation software for printed circuit board designs, for the hobby, hacker, and maker community. [1] [2] CircuitMaker is available as freeware, and the hardware designed with it may be used for commercial and non-commercial purposes without limitations. [3]
In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI/IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations.
A circuit breaker analyzer is an instrument that measures the parameters of a circuit breaker. [1]In 1984, Megger patented a digital circuit breaker analyzer, controlled by a microprocessor. in 2020 few companies develop software to control circuit breaker analyzers from different devices such as computers, tablet computer, smartphones and others.

A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
By permitting the automatic racking of the circuit breaker from a remote location, the remote racking systems move service personnel outside the arc flash protection boundary, thus reducing the need for a full-body arc flash hazard suit. A remote switch operator is used to remotely operate various types and styles of circuit breakers and controls.
