CQD215 - 15Amp Circuit Breaker

CQD215 - 15Amp Circuit Breaker

The CQD215 Siemens CQD miniature circuit breaker is a 15 Amp, 2-pole breaker used in commercial and industrial electrical systems where 277/480V circuits need dependable branch protection in a compact DIN rail format. You’ll typically find this type of breaker in lighting panels, control cabinets, and distribution boards, especially in facilities that rely on organized DIN rail layouts to keep wiring clean and service work straightforward.

This unit is rated for 480/277 VAC systems and provides a 14 kA interrupting capacity, making it suitable for standard commercial branch-circuit protection. The 2-pole design allows both conductors to disconnect simultaneously, which is commonly required for 277/480V applications in lighting and distribution systems.

At its core, it’s a straightforward breaker built for real-world panel work—easy to install, easy to replace, and designed to keep circuits protected in systems where consistency and layout organization matter.
