Mode 1 and Mode 2 are used by the Federal surge suppressor CID purchase specification. Mode 1 is the ground wire protection mode (no surge diversion to the ground wire). Mode 2 permits ground wire contamination, and is sometimes referred to as “all mode” suppression, or ground contamination mode.

Metal Oxide Varistor (MOV)

A component which behaves like a low value resistor when a certain voltage threshold is exceeded. These components “wear out” with use and should be replaced periodically.

Maximum Continuous Operating Voltage (MCOV)

This is the magnitude limit of continuously applied voltage. This is a UL rated property of surge protectors. If the voltage is maintained above this voltage, the protector will fail. With Zero Surge Wide Voltage Range technology, the MCOV is 175 volts. Most plug in surge protectors have an MCOV of <150 volts.

Local Area Network (LAN)

An interconnection of computers, printers and other peripherals permitting the sharing of hardware and software resources.

The peak voltage that is let through a surge protection device from a surge to the protected equipment. The theoretical lower limit is about 180 volts peak for standard 120 volt AC power. Lower is better. Also called SV (Suppressed Voltage) by UL. An important measure of suppressor performance. UL by rule will not issue a rating for less than 330 volts. Any device that has a let-through voltage of lower than 330 volts is listed as "<330 volts" which is what all Zero Surge products are rated.

An electrical device connected to a power source. The "load" side of a circuit is where power is consumed.

Some protectors are rated in joules, meaning that if a surge exceeds the joule rating, the protector will likely be damaged. The joule rating of protectors reduces with each surge that the device encounters. It is not an official safety rating of the product. Zero Surge products do not have a Joule rating because our products do not degrade with use. The amount of energy that our products can absorb is limited by the wiring in a building. At some point the wire in the wall will break down before our product would and at that point the circuit is no longer powered.

A unit of energy, also known as watt-seconds.

A nationally recognized testing laboratory ensuring products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. Originally known as the Edison Test Lab (ETL), it is the oldest running independent test lab in the United States.

Intersystem Bonding Termination

A device that provides a means for connecting bonding conductors for communications systems to the grounding electrode system. The ground lines of your building’s cable TV, phone, fire alarm systems, and power systems are all bonded together along with the power system neutral at the service entrance.

You filter your water. You filter your air. Do you filter your power?

Q: Let-Through Voltage

The peak voltage that is let through a surge protection device from a surge to the protected equipment. The theoretical lower limit is about 180 volts peak for standard 120 volt AC power.
