types of Circuit Breakers

انواع قطع کننده مدار

Key Takeaways Circuit breakers are classified by voltage level (low, medium, high), arc-quenching medium (air, vacuum, SF6, oil), application (residential, commercial, industrial), and trip characteristics (Type A, B, C, D). MCBs (6-125A) suit residential applications, while MCCBs (100-2500A) serve commercial/industrial needs, and ACBs (800-6300A) protect heavy industrial systems. Specialized breakers like RCCB/RCD prevent electric shock
