CyberPower 3-Phase Circuit Breaker (175A)

The CyberPower SMUCB175UAC is a 175 amp three phase circuit breaker that installs directly on a CyberPower Smart App Online Modular UPS. By adding input and output overcurrent protection at the UPS itself, it gives technicians a convenient disconnect point when upstream breakers sit far away or were never installed. This simple change reduces the time required for maintenance and helps prevent accidental exposure to live circuits.

The breaker is engineered for systems that draw up to 40 kilovolt amperes, such as medium size data centers, network closets, or production lines that rely on continuous power. When paired with the CyberPower SM040KAMFA UPS, it creates an integrated power solution that isolates faults quickly and keeps critical loads running.

Installation is straightforward. The unit ships with mounting hardware that matches CyberPower modular cabinets, allowing it to slide in next to battery or power modules without extra brackets. Once in place, clear labeling on the front panel shows input and output status, so facility staff can confirm protection at a glance.

Safety and compliance are central to the design. The SMUCB175UAC meets UL489, CSA C22.2, and IEC 60947 requirements, which streamlines inspections and supports a wide range of regional codes. Whether you manage a busy server room or an industrial power hallway, this circuit breaker provides the circuit isolation and equipment protection needed for reliable operation.
