Molded-Case Circuit Breakers

The ACW Series of molded-case circuit breakers are designed to disconnect power and provide circuit protection for low-voltage distribution systems against overloads and/or short circuits. The breakers can be ordered in one of four different compact frames — voltage and frequency rating, interrupting rating, continuous-current rating, and accessories.

Two levels of short-circuit interrupting capacity are available: “P” for standard industrial and commercial applications and “W” for high-performance applications.

Additionally, cascading protection offers an economical approach by facilitating the use of downstream, low-cost, low-fault level breakers to offer savings in both the cost and size of equipment.
