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.
Circuit Protection Categories

Circuit Protection Components (247 suppliers)

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.

Dataline and DC Signal Surge Suppressors (184 suppliers)

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

Electrostatic Discharge (ESD) Suppressors (48 suppliers)

ESD suppressors are semiconductors that protect electronic components and systems from electrostatic discharge (ESD).

Fuse Holders (476 suppliers)

Fuse holders are devices for containing, protecting and mounting fuses. Blown fuses can be changed quickly and easily when used in conjunction with a fuse holder.

Fuses (937 suppliers)

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

Gas Discharge Tubes (GDT) (65 suppliers)

Gas discharge tubes (GDT) or gas tube arrestors (GTA) provide protection against voltage and current surges in electronic and electrical equipment. They include spark gaps, simple devices with two or three conducting electrodes separated by a gap filled with a gas such as air.

Ground Fault Circuit Interrupters (GFCI) (58 suppliers)

Ground fault circuit interrupters (GFCI) disconnect a circuit when the current between the neutral conductor and the live conductor becomes unbalanced. GFCIs are also known as residual current devices.

Ground Fault Relays (31 suppliers)

Ground fault relays protect electrical equipment from ground faults. A ground fault is an unintentional current path between a current-carrying conductor and a grounded surface.

Metal Oxide Varistors (MOVs) (72 suppliers)

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

Thermal Cutoffs and Thermal Fuses (78 suppliers)

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.

Transient Voltage Suppressor Diodes (TVS) (137 suppliers)

Transient voltage suppressor (TVS) diodes are designed to limit over-voltages. They can dissipate high amounts of transient power in a short period of time.
