Description

Description of NDW2 Series

The NDW2 series of air circuit breakers (hereinafter referred to as ABCs) can be applied to the distribution network with the AC 50Hz/60Hz, the rated current of 200A - 6300A, the rated insulation voltage of 1000 V, the rated working voltage of AC220V/230V/240V, AC380V/400V/415V, AC440V/480V, AC660V/690V. NDW2-4000 can also be applied to the distribution network with the rated working voltage of AC1000V for distribution of electrical energy and protecting circuit and power equipment from overload, under-voltage, short circuit, single phase grounding and harm of other faults, and can also be used as isolation switch at the same time. The circuit breaker has multiple protection functions. It can avoid unnecessary sudden power failure while realizing highly accurate selective protection, and improve the reliability and security of the power supply system.

FAQs

Questions & Answers for NDW2 Series

• What is the use of air circuit breaker?
  Air Circuit Breaker (ACB) is electronic equipment that is used for the protection of electric circuits from short circuits or overcurrent. The ACB operates at atmospheric pressure in air. ACB is used in the switching mechanism and protection of the electrical system.
• Why is it called an air circuit breaker?
  It is a circuit breaker with compressed air as arc quenching medium to exterminate the arc produced when the contacts are separated. So this is called Air Circuit Breaker.
• What is difference between VCB and ACB?
  The key difference between an air circuit breaker and a vacuum circuit breaker is current rating. With current rating from 1001 A to 10000 A, ACB (Air circuit breaker) is often used in Main Electrical Panels as well as for large industrial plant, where the breakers are arranged in drawn-out enclosures for ease of maintenance. The current rating of VCB (Vacuum circuit breaker) is up to 3000 Amperes and can be applied at up to 35 thousand volts.Contact C&S Electric for more information on air blast circuit breaker.
• How many types of air circuit breakers are there?
  There are mainly two types of ACB are available. Plain air circuit breaker. Air blast Circuit Breaker.
• What is difference between ACB and MCCB?
  An ACB is physically larger, but more cost-effective for higher ratings. current waveform (within five milliseconds in a 50 Hz system). The fault current flowing through the MCCB never reaches its peak, and the fault energy allowed downstream is limited.
• How do you maintain a circuit breaker?
  Molded case Circuit Breakers should be exercised at least once per year. Routine trip testing should be performed every 3 to 5 years. Low-voltage Circuit Breakers should be inspected and maintained every 1 to 3 years, depending on their service and operating conditions.
