CQD315 - 15Amp Circuit Breaker Description
CQD315 - 15Amp Circuit Breaker
If you’re working inside a Siemens CQD panel, the CQD315 is one of those breakers that keeps things simple. It’s a 3-pole, 15 amp circuit breaker designed for 480/277V systems, and it’s typically used in setups where you’re maintaining an existing panel rather than redesigning anything. In other words, it’s built for the practical side of electrical work—swapping out a like-for-like component so the system keeps running the way it should.
You’ll usually see this breaker in commercial lighting circuits, small three-phase loads, and control panel applications. At 15 amps, it handles lighter branch circuits, while the 14kA interrupt rating provides standard protection for this class of equipment. It’s a straightforward fit when consistency with existing Siemens CQD systems matters more than anything else.
Because it mounts on DIN rail, installation stays quick and tidy. It locks into place cleanly, helping keep panel layouts organized and making future maintenance easier when the time comes.
