Questions & Answers for NDM3G Series

  • What is a molded case circuit breaker?
    Moulded Case Circuit Breakers Explained. ... A moulded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect the electrical circuit from excessive current, which can cause overload or short circuit.
  • 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).
  • What is MCCB and its working?
    Molded Case Circuit Breaker (MCCB) is a circuit breaker and trip device assembled in a mould case. Also it can automatically cut off electric power in case of overload and short circuit. It is meant for higher rated current and is commonly used in Industrial applications.
  • What causes MCCB to trip?
    Circuit overloading is known to be the most common reason for circuit breaker tripping. It simply means that we're running too many heavy power-consuming devices at the same time on the same circuit. The next most dangerous cause is a short circuit.
  • How do molded case circuit breakers work?
    The traditional molded-case circuit breaker uses electromechanical (thermal magnetic) trip units that may be fixed or interchangeable. An MCCB provides protection by combining a temperature sensitive device with a current sensitive electromagnetic device. Both these devices act mechanically on the trip mechanism.
  • Why we use Mccb instead of MCB?
    If evaluated from their power capacities, the MCB is essentially used for low-current requirements, such as, home wiring or small electronic circuits; while the MCCB is better used for high-power requirements. Type of electrical switch which protects the circuit from overload or short circuit.
