Transient voltage surge suppressors protect against temporary excess voltage and/or current in an electrical circuit that has been disturbed

Three phase surge suppressors protect equipment from transient overvoltages present on AC three phase power lines. Three phase surge suppressors are not plug-in style devices

Dataline and DC signal surge suppressors protect equipment from transient overvoltages present on data or DC signal lines

Single phase surge suppressors protect equipment from transient overvoltages present on AC single phase power lines. They are not plug-in style devices

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

Thyristor surge suppressors are semiconductor chips used to protect circuits and devices from over-voltage and over-current

Gas tube arresters (GTA) or gas discharge tubes (GDT) provide protection against voltage and current surges in electronic and electrical equipment

Power strips are used in applications where multiple AC outlets are needed, often without surge or line noise protection

Circuit protection devices are used to protect electronic components from unwanted transients such as current and voltage surges, electrostatic discharge (ESD), lightning, spikes and other signals that can imperil the operation or damage the component

Grounding rods and lightning protection systems provide reliable electrical connection to the earth or ground and can vary from simple copper rods to sophisticated electrolytic rod systems with active soil moisture replenishment.

Three phase uninterruptible power supplies (UPS) are devices that operate in conjunction with existing electrical systems to provide power conditioning, back-up protection and distribution for electronic equipment loads.

Single phase uninterruptible power supplies (UPS) sit between an AC outlet (i.e., a wall outlet or power strip) and an electronic device (e.g., computer, server, or phone equipment) to provide power conditioning, back-up protection and distribution for electronic equipment loads.

Power or line conditioners regulate, filter, and suppress noise in AC power for sensitive computer and other solid state equipment.

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

Resistors are electrical components that oppose the flow of either direct or alternating current. They are used to protect, operate, or control circuits.
