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). NXM series offers multiple ratings from 10A - 1250A to match your needs.

Q: Can NXM be used for motor protection?

A: Yes, NXM 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.
