CQD360 - 60Amp Circuit Breaker

CQD360 - 60Amp Circuit Breaker

When you’re working inside an existing Siemens CQD panel, the CQD360 is the kind of component that keeps everything consistent without forcing changes to the system around it. It’s a 60 amp, 3-pole molded case circuit breaker designed for 480/277V applications, typically used in commercial and industrial electrical distribution where keeping an established setup running smoothly is the main priority.

In real-world use, this breaker is commonly found in three-phase branch circuits, lighting distribution panels, and general power systems. The 60A rating gives it the capacity for moderate-load applications, while the 14kA interrupt rating provides standard protection for fault conditions in this class of equipment. It’s a straightforward, dependable fit for facilities that rely on existing Siemens CQD infrastructure.

Because it belongs to the CQD family, it’s most often chosen for maintenance, repair, or direct replacement work, where compatibility matters just as much as performance. It helps keep panels operating the way they were originally designed, without introducing unnecessary redesigns or mismatched components.

The DIN rail mounting system makes installation clean and efficient, helping electricians maintain organized panel layouts and making future servicing quicker and more manageable.
