Description

Description of NDP3A Series

The NDP3A series of distribution boxes are applicable to the indoor environment with the AC 50Hz or 60Hz, and the rated working voltage of 440V at temperature usually no more than 35℃ and occasionally up to 60 ℃. They are used for protecting circuit breakers, switches, sockets and other electrical accessories from external impacts (such as mechanical shock, invasion of liquid substances, etc.). They are widely used in the electrical accessory housing of fixed electrical installation in the domestic and construction applications.

FAQs

Questions & Answers for NDP3A 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).
