Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions

Circuit tracers or signal tracers are used to troubleshoot circuits. They are relatively simple electrical testing instruments that enable electricians and other users to locate, trace and identify common electrical problems such as breakers, shorts

Panelboards and switchgear are electrical distribution devices that convert incoming electrical power into several smaller circuits and provide overload protection in the form of fuses or circuit breakers

Electrical contacts and contact materials are soft, high-conductivity, oxidation- resistant materials that are used in circuit breakers, relays, switches, and electrical discharge machining (EDM) applications.  They often have a second phase in order to provide anti-welding and/or arc resistance

Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits

Switch boots protect switches from contaminants such as dirt, dust, gas, and liquids.  They are generally tough, pliable silicone rubber devices for toggle, pushbutton, rocker and rotary switches.

Electrical contact and electrode materials are soft, high conductivity, oxidation resistant materials used in circuit breakers, relays, and for EDM applications

Specialty electrical distribution and protection products are specialty or proprietary products related to electrical distribution and circuit protection

Metal oxide varistors (MOV) are semiconductors that protect electronic components and systems from transient voltages.

Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants

Current sources provide reliable current for electrical component testing and for powering specialized components.

Plugin style surge suppressors plug into wall outlets to protect equipment from transient overvoltages.

Ground Fault Circuit Interrupter (GFCI) testers check for the integrity of GFCI devices

Encapsulants and potting compounds are resins or adhesives that are used to encapsulate circuit boards and semiconductors, fill containers of electronic components, and infiltrate electrical coils. They provide environmental protection, electrical insulation and other specialized characteristics

Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices.
