Industrial QY38U2150B0ZL 3 Pole Circuit Breaker

The CBI QY38U2150B0ZL is a 3-pole, 150 A DC circuit breaker engineered for DIN-rail mounting, offering 80 V DC operation and a 10 kA short-circuit breaking capacity. As part of CBI's QY series, it uses a DC U2 protection curve and is designed for compact panel installations, enabling reliable protection for DC distribution networks in industrial automation. The three-pole design provides coordinated protection across three conductors in a DC power path, making it well suited for 80 V DC distribution networks and other DC-powered control panels. DIN-rail mounting and the QY family form factor facilitate easy integration with other QY devices to create modular protection schemes in electrical enclosures, while its 150 A rating supports mid-range DC circuits without occupying excessive space. Key verified specifications include nominal current 150 A, DC rating 80 V, breaking capacity 10 kA, and the U2 operating curve, all encapsulated in the part number QY38U2150B0ZL for a DIN-rail 3P solution.
