Prepared for preliminary research by the ZITHA SPECIALTY knowledge desk. Confirm fire performance, mechanical protection, loss budgets and installation requirements against current standards and product documentation.

Nader low-voltage distribution boxes, including the NDP1A and NDP3 series, are designed for safe indoor electrical distribution with rated voltages from 220V to 440V and currents from 1A to 63A.Overview

Nader manufactures high-end low-voltage electrical products, and their distribution boxes are used to house circuit breakers, switches, sockets, and other electrical accessories, providing protection against mechanical impacts, dust, and liquid intrusion . These boxes are suitable for residential, commercial, and industrial applications, ensuring safe and organized power distribution.

Key Series
  • NDP1A Series: This concealed distribution box is designed for indoor use with AC 50Hz or 60Hz, rated working voltage of 220V to 440V, and operating temperatures generally not exceeding 35°C, occasionally reaching 60°C. It is widely used for household and building fixed electrical devices, offering protection for circuit breakers, switches, and sockets .
  • NDP3 Series: A modular terminal combination box suitable for AC 50Hz or 60Hz, rated voltage 230V to 400V, and rated current 1A to 63A. It provides protection for electrical accessories against external influences and is made with insulated, flame-retardant materials. The NDP3 series features a transparent or opaque cover, metal box body with electrostatic spraying, and is suitable for concealed installation .
Features
  • Protection: Safeguards against mechanical impact, dust, and liquid ingress. Some models also integrate surge protection devices (SPDs) to protect against lightning and transient overvoltage .
  • Material: Made from flame-retardant plastic or 1.2mm cold-rolled steel with corrosion-resistant surface treatment .
  • Installation: Designed for concealed or surface mounting, with options for knock-down holes and grounding poles to meet different user requirements .
  • Certification: Products like the NDP3 series have obtained China Compulsory Certification (CCC), ensuring compliance with safety standards .
Integration with Circuit Protection

Nader distribution boxes are compatible with a range of circuit breakers:

  • MCBs (Miniature Circuit Breakers): NDB1-63, NDB2-63, and NDB6AZ-63H series provide short-circuit, overload, and isolation protection for AC and DC systems, with rated currents from 1A to 125A .
  • Residual Current Devices (RCCBs): NDB1L-32 series offers leakage protection alongside short-circuit and overload protection .
  • Surge Protection Devices (SPDs): NDU series protects against lightning and transient overvoltage, suitable for industrial, civil, and telecommunication systems .
Applications
  • Residential and commercial buildings for safe power distribution.
  • Industrial facilities for low-voltage terminal power distribution.
  • Telecommunication and data centers for DC and AC protection.
  • Integration with energy, infrastructure, and civil engineering projects . Nader low-voltage distribution boxes provide a reliable, certified, and versatile solution for organizing and protecting electrical circuits in various environments.
