| ''Guidelines to consider when choosing a Surge Protection Device 1. Geographic location a. Exposure to utility grid switching b. Locations susceptible to brownouts or frequent utility power switching 2. Point of installation (also see types of SPD within definitions) a. Protect equipment which is located near switching motors or transformers b. Sensitive equipment: Computers, home theater systems, appliances which have sensitive electronics should be protected System Voltage The wiring diagrams characterize common voltage configurations available for the products. Refer to individual product pages for models available in below configurations. Match the voltage configuration below with your voltage configuration at your service entrance, distribution panel or panelboard location where you want protection.'' |
| ''Surge: A sudden and sharp increase of current or voltage within electric circuits. SURGE PROTECTIVE DEVICE (SPD): A device used to limit a surge on equipment by diverting or limiting it. SPDs were previously known as Transient Voltage Surge Suppressors or secondary surge arresters. SHORT CIRCUIT CURRENT RATING (SCCR): The measurement of how much current the electrical system can supply during a fault condition. This value determines where an SPD may be installed. (Listed on the product) NOMINAL DISCHARGE CURRENT (In): Peak value of the current through the SPD having a current wave shape of 8/20 where the SPD remains functional after 15 surges. (Listed on the product) NOMINAL SYSTEM VOLTAGE: The voltage level at which a system normally operates. Nominal system voltages include, but are not limited to, 120, 208, 240, 277, 347, 480, 600 VAC. (Listed on the product) MODES OF PROTECTION: Electrical paths within a system which an SPD offers defense against surge events. Examples of protection include, Line to Neutral (L-N), Line to Ground (L-G), Line to Line (L-L) and Neutral to Ground (N-G). (Listed on the product) VOLTAGE PROTECTION RATING (VPR): The value assigned by UL which specifies the measured limited voltage value of the SPD. VPR rating is formally known as the “suppressed voltage rating”. (Listed on the product) MAXIMUM CONTINUOUS OPERATING VOLTAGE: The maximum RMS voltage that may be applied to each mode of a surge protection device. (Listed on the product)'' |
''Clamping Voltage (Also known as Let-Through Voltage) The voltage at which a surge suppressor performs its suppression tasks such as diverting (shunt) the surge from line to ground or absorbing the excessive energy. Common Mode When relating to SPDs, common mode refers to surge protection components provided between L-G and N-G modes. Maximum Continuous Operating Voltage (MCOV) The maximum voltage that can be continuously applied to each mode of the SPD without degradation. Maximum Surge Current Rating The maximum 8x20us Surge Current Amps an SPD can withstand 1 time without performance degradation of more than 10%. Nominal Discharge Current (IN) The peak value of an 8/20 μs current waveform, selected by the manufacturer, for which an SPD (Type 1 or Type 2 only) remains functional after 15 surges - Type 1 devices require testing at 10 or 20 kA and Type 2 devices can be tested using a 3, 5, 10 or 20 kA. Normal Mode When relating to SPDs, normal mode refers to surge protection components provided between L-L and L-N modes. Per Mode A “mode” is a potential path for a surge to be diverted to (such as L-N, L-G, N-G). Per Phase The maximum amount of surge current a SPD can shunt to ground during a surge event on one phase. Short Circuit Current Rating (SCCR) The suitability of an SPD for use on an AC power circuit that is capable of delivering not more than a declared current at a declared voltage during a short circuit condition. Surge A short-duration overvoltage spike or disturbance on the ac power line, having duration of a few milliseconds or less. Suppression Voltage Rating (SVR) Term used to define the clamping voltage when subjected to the UL 1449 2nd Edition Measured Limited Voltage Test - this test has proven insufficient to adequately evaluate SPD performance, and has been replaced by the Voltage Protection Rating (VPR). Temporary Overvoltage (TOV) An overvoltage on the AC power line that is at a given location of relatively long duration (seconds, even minutes). Type 1 Surge Protection Device Permanently connected SPDs intended for installation between the secondary of the service transformer and the line side of the service equipment overcurrent device, as well as the load side, including watt-hour meter socket enclosures and intended to be installed without an external overcurrent protective device. Type 2 Surge Protection Device Permanently connected SPDs intended for installation on the load side of the service equipment over current device; including SPDs located at the branch panel. Type 3 Surge Protection Device Point of utilization SPDs, installed at a minimum conductor length of 10 meters (30 feet) from the electrical service panel to the point of utilization, for example cord connected, direct plug-in, receptacle type and SPDs installed at the utilization equipment being protected. Type 4 Surge Protection Device Component assembly consisting of one or more Type 5 components together with a disconnect (integral or external) or a means of complying with the limited current tests. Type 5 Surge Protection Device Discrete component surge suppressors, such as MOVs that may be mounted on a PWB, connected by its leads or provided within an enclosure with mounting means and wiring terminations. Voltage Protection Rating (VPR) The new terminology for what was previously known as clamping voltage, suppression voltage rating (SVR), or let-through voltage. It represents the clamping voltage when subjected to the UL 1449 3rd Edition Measured Limited Voltage Test. This newly modified test is performed at significantly higher currents (6kV @ 3000A vs 6kV 500A) to more accurately reflect real world performance. Note: As with all SPDs, this standard only protects against surges that travel along the electrical pathway and does not protect against direct lightning strikes traveling down non-electrical paths. For Type 2 SPDs, your SPD is only as useful as your weakest breaker. Make sure sizing of breakers within the electrical panel are at least a 20 amp dual pole breakers to aid in preventing short circuits before the SPD becomes functional. Type 1 SPDs are normally mounted before the panels which would not include a breaker.'' |
