CQD220 - 20Amp Circuit Breaker
The CQD220 Siemens CQD miniature circuit breaker is a 20 Amp, 2-pole breaker used in real-world commercial and industrial panels where 480/277V circuits need dependable, everyday protection. You’ll usually find it in lighting panels, control cabinets, and distribution boards, especially in buildings that rely on DIN rail setups to keep wiring organized and easy to service later.
It’s rated for 480/277VAC systems and provides a 14kA interrupting capacity, making it suitable for typical commercial branch circuit protection. The 2-pole design disconnects both conductors together, which is standard for this voltage range and commonly used in lighting and distribution applications.
At the end of the day, it’s a practical breaker that does a simple job well—keeping circuits protected in systems where consistency, easy replacement, and clean panel organization matter most.
