NDP3 Series Distribution Box
Updated:August 12,2022 16:18PM

Nader NDP3 series modular terminal combination box is applicable to circuit terminals with AC 50Hz (or 60Hz), rated working voltage of 230V to 400V and rated current of 1A to 63A. It is usually not more than 35 ℃ and occasionally reaches 40 ℃. It is used to provide protection for circuit breakers, switches, sockets and other electrical accessories against external influences (such as mechanical impact, invasion of solid substances, etc.).

Questions & Answers for NDP3 Series

  • What is the function of miniature circuit breaker?
    A Miniature Circuit Breaker (MCB) is an automatically operated electrical switch used to protect low voltage electrical circuits from damage caused by excess current from an overload or short circuit.
  • What is miniature circuit breaker how it works?
    A miniature circuit breaker (MCB) automatically switches off the electrical circuit during an abnormal condition of the network means in overload condition as well as faulty condition. Nowadays we use an MCB in a low voltage electrical network instead of a fuse. Handling an MCB is electrically safer than a fuse.
  • What is mean by miniature circuit breaker?
    miniature circuit breaker: a small trip switch operated by an overload and used to protect an electric circuit, esp a domestic circuit as an alternative to a fuse.
  • How does a house breaker work?
    Inside each circuit breaker is a spring hooked over a small piece of solder (a melt-able fusible alloy). Each breaker is connected to an electrical wire that runs through your house. The electricity that flows through your house runs through the solder.
  • What is the advantage of miniature circuit breaker?
    MCB (Miniature Circuit Breaker) is a circuit breaker with optimum protection facilities of overcurrent and short circuit only. Its basic function is to detect the fault condition and interrupt the current flow. it avoids overheating in case of excess current & provides fire protection.
  • What is the difference between MCCB and MCB?
    MCB is miniature circuit breaker which is used to break small currents. Like in domestic LT circuits. The ratings usually end up to 100 A. MCCB is a Module case circuit breaker which has a rugged construction as it can break larger currents usually from (100-1000A).
