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.

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.

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
