SCHURTER’s latest series of appliance outlets NR020 and NR021 combine classic features with new ones to meet increased fire protection and safety standards according to UL 498 Tamper Resistant, as well as facilitating compliance of receptacles used in Household and Commercial Furniture and Furniture Power Distribution Units (FPDUs), according to UL 962 and UL 962A. Higher temperature ratings and added configurations for series NR010 and NR020 respond to power demands facing Datacom infrastructures today.
Higher Temperature Rated Receptacles
Packing density of equipment for data communication and storage continues to be regularly revolutionized with the surge of usage and functionality. Increasing ambient temperatures go hand in hand with these advancements, as demand trickles down to the smallest components to keep pace with emerging needs of the appliance manufacturers. The NR010 and NR020 series have an operating temperature range of -25 ˚C to 150 ˚C in response to the power needs of the Datacom industry. In addition, the NR010 with IDC terminals in Along- and Cross orientation to the Pin-Axis provides a version with an independent L terminal for the IDC-Along version. The neutral and ground terminals can still be bussed, while the line terminal can be used for maximum load according to UL rating 15 A, 125 V. It also extends the capability of adding functionality to each outlet individually.
Tamper Resistant Receptacles – TRR
The concept of tamper-resistant receptacles is not a recent development; these devices have been a standard product offering of wiring device manufacturers for many years. The devices are designed to protect individuals (primarily children) from accidental shock resulting from the insertion of foreign objects. The US National Electric Code NEC® Article 406.12 states that all 15- and 20-ampere, 125- and 250-Volt nonlocking-type receptacles installed in dwelling units must be Tamper Resistant. In 2017, changes to the Code expanded on these requirements and locations. Previously, tamper-resistant receptacles were required in dwelling units, guest rooms and guest suites of hotels and motels, and in childcare facilities. The expanded code brings these safety devices to preschools and elementary education facilities; business offices, corridors, waiting rooms and the like in clinics, medical and dental offices and outpatient facilities; to assembly occupancies such as places of awaiting transportation, gymnasiums, skating rinks, auditoriums; and to dormitories. These expanded locations are areas that small children frequently occupy.
Tamper resistant receptacles feature a UL recognized safety shutter system that prevents the insertion of foreign objects into a receptacle. The safety shutters will only open upon simultaneous insertion of two plug blades. Additional tests including Probe Test, Impact Test, Mechanical Endurance Test and Dielectric Voltage Withstand Test for Tamper Resistant Receptacles TRR are included in UL 498. After passing all the above performance tests, tamper-resistant receptacles must have either the words “Tamper Resistant" or the letters "TR" (minimum 3/16 inches high) on the device as a clear indication that this is a tamper-resistant receptacle.
SCHURTER’s NR021 NEMA 5-15R Tamper Resistant series meets the expanded code requirements according to UL 498. Additionally, with the option of an added insulated wall between the L, N terminals, compliance with the Spill Test, outlined in UL 962 Sec. 62, is more cost effective and efficient for manufacturers of Household and Commercial Furniture and Furniture Power Distribution Units (FPDUs).
