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

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

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

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

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

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

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

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.

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

Step recovery diodes produce an abrupt turn-off (step) time by allowing a very fast release of stored charge when switching from forward to reverse bias, and from reverse to forward bias.

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

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

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

Cable protectors cover wires, cables, hose or pipe in high traffic areas to protect them from damage

Thermal cutoffs and thermal protectors are nonresetting, thermally sensitive devices designed to protect domestic electrical appliances and industrial equipment from fire. They are sometimes described as thermal one-shot fuses
