Cutler-Hammer CAH3175 U Molded Case Circuit Breaker

The Cutler-Hammer CAH3175 U molded case circuit breaker is a 175 A, 3-pole device rated for 240 V. From the Cutler-Hammer CAH family, this molded‑case breaker is designed to provide overcurrent protection for electrical distribution circuits in panels and equipment. The 3-pole configuration means it can interrupt three conductors simultaneously, making it suitable for multi-conductor branch circuits that require coordinated protection in a single device. The CAH3175 U designation identifies this specific model within the CAH line, and the 175 A / 240 V rating communicates the maximum current and operating voltage the device is designed to handle. This type of breaker is typically used in electrical distribution to safeguard circuits from overloads and short circuits, supporting reliable protection in commercial or industrial settings where larger feeders require robust interruption capability.
