8 / 18 page 8 NIC COMPONENTS CORP. www.niccomp.com www.lowESR.com www.RFpassives.com www.SMTmagnetics.com SPECIFICATIONS ARE SUBJECT TO CHANGE Leaded Metal Oxide Varistors NVR Series Type Description Type 2 Permanently connected SPDs intended for installation on the load side of the service equipment overcurrent device; including SPDs located at the branch panel. Type 3 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. See marking in 64.2. The distance (10 meters) is exclusive of conductors provided with or used to attach SPDs. TABLE 1 - DEFINITION OF UL SPD APPLICATION TYPES Type 3 (Minimum of 30 feet of conductor between service disconnect and SPD) Type 2 (SPD located after service disconnect) Type 3 applications include SPDs that are cord-connected, plugged directly into the socket or integrated in the outlet. They must be installed a minimum of 10 meters (30 feet) from the electrical service panel. An example would be a home appliance that is installed beyond 10 meters (30 feet) from the electrical service panel, and it uses varistors in power in for surge protection, the Varistor should meet SPD Type 3. Type 2 applications include indoor AC applications located after the service disconnection. TABLE 2 - Other applications as described in the table below: EXAMPLES OF SPD APPLICATION TYPES Intended End-Use (SPD Type) NVR Sizes (Values) Part Diameter Voltage Protective Rating Test & Waveform Waveform Peak Voltage (Vp) Peak Current (Ap) Other Applications NVR05 (180 ~ 680) 5mm 600V (1.2x50uS*) 50V (8x20uS**) NVR05 (820 ~ 471) NVR10 (180 ~ 680) 5mm 10mm 3000V (1.2x50uS*) 250V (8x20uS**) NVR7 (180 ~ 680) 7mm 1200V (1.2x50uS*) 100V (8x20uS**) NVR7 (820 ~ 821) NVR14 (180 ~ 680) 7mm 14mm 1000V (1.2x50uS*) 500V (8x20uS**) NVR7 (820 ~ 821) NVR14 (180 ~ 680) 7mm 14mm 2000V (1.2x50uS*) 1000V (8x20uS**) For SPD Type 3 NVR14 (820 ~ 182) NVR20 (820 ~ 182) 14mm 20mm 6000V (1.2x50uS*) 3000V (8x20uS**) Notes: * 1.2x50uS - 1.2uSec. rise time and 50uSec fall time ** 8x20uS - 8uSec. rise time and 20uSec fall time Industry standard benchmark to quantify the component’s response to a typically fast transient |
