CQD3100 - 100Amp Circuit Breaker
The Siemens CQD3100 is a 3-pole, 100 amp molded case circuit breaker designed for you to use in 480/277V commercial electrical distribution systems. It’s part of the Siemens CQD series and is commonly used in existing panel installations where maintaining system compatibility matters. In many cases, it’s selected for your replacement work—where the goal is to match the original breaker type and keep the panel operating without changes to layout or wiring.
Because it uses a DIN rail mounting design, installation is straightforward and helps keep panel interiors organized. Once installed, it sits neatly within the CQD system and supports routine maintenance or replacement work without adding extra complexity.
