Frequently Asked Questions

Q: What is the difference between MCCB and ACB?

A: MCCB (Molded Case Circuit Breaker) is used for currents up to 1600A in distribution panels. ACB (Air Circuit Breaker) handles higher currents (1000A-6300A) and is used in main power distribution boards. Choose MCCB for branch circuits and ACB for main incoming power.

Q: How do I select the right current rating?

A: Calculate your maximum load current and add 20-25% safety margin. For motor applications, consider the inrush current (typically 6-8 times rated current). NA1 series offers multiple ratings from 1000A to match your needs.

Q: Can NA1 be used for motor protection?

A: Yes, NA1 series supports motor protection with adjustable thermal-magnetic trip units. Select a rating that accommodates the motor's starting current while providing overload protection during normal operation.

Description

Application:

Chint NA1 series air circuit breaker is suitable for the circuit of AC 50Hz/60Hz with rated service voltage 400V, 690V and rated service current up to 6300A. It is mainly used to distribute electric energy and protect circuits and electric equipment against over-load, under-voltage, short-circuit and single-phase earthing fault.

With intelligentized and selective protection functions, the breaker can improve the reliability of power supply, and avoid unnecessary power failure. The breaker is applicable for power stations, factories, mines (for 690V) and modern high- buildings, especially for the distribution system of intelligentized building.

Standard: IEC/EN 60947-2.
