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.

The devices also facilitate the 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. 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. 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). The NR010 and NR020 series have an operating temperature range of -25 to 150˚C in response to the power needs of the Datacom industry. In addition, the NR010 with IDC terminals provides a version with an independent L terminal. 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.
