Practical Applications for Noark’s Molded Case Circuit Breakers

If your business is looking for ways to manage overcurrent faults in your electrical systems, Noark Electric’s Molded Case Circuit Breakers (MCCBs) are the perfect product solution.

It is a requirement in electrical distribution systems to have Molded Case Circuit Breakers (MCCB), as they provide both overload protection as well as short-circuit protection. The main power distribution board (MPDB) of a facility is usually equipped with MCCBs, which allows for protection, coordination, associated control, isolation, and shutdown of the entire system in the case of an emergency.

In the case of molded case circuit breakers (MCCBs), these safety devices are used to protect the conductors of electrical circuits, feeder circuits, downstream electrical equipment or loads against overloads and short circuits. In order to mitigate damage to an electrical system, this device automatically trips off and isolate itself from  the power supply when there is a fault or overcurrent situation, thus preventing damage to the system, circuit or electrical load connected to it.

MCCBs are used in electrical systems of less than 1000V. The general classification for Voltage levels are:

  • Low voltage – less than 1kV (some classification use 600V).
  • Medium Voltage – 1kV up to 40kV.
  • High voltage – from 40kV.

Noark manufactures high quality switchgears with Global and North American certifications in the listed voltage categories as well as extra high Voltage (EHV) and UHV (ultra high voltage) systems. Please contact them to learn more.

What are common Molded Case Circuit Breaker (MCCB) Applications?

MCCBs can be used in a variety of applications to manage electrical systems’ overcurrent protection. These applications are found in electrical systems used across many segments including industries, manufacturing, building & infrastructure, residential application, critical & standby power, and many more.

The following are some examples of electrical loads/systems that use the Molded Case Circuit Breaker for protection:
  • Electric Motors;
  • Generators;
  • Electric Feeders; and more.
