CQD130 - 30Amp Circuit Breaker
The CQD130 Siemens CQD miniature circuit breaker is a 30 Amp, 1-pole breaker used in real-world commercial and industrial panels where 277V circuits need basic, consistent protection. You’ll usually find it in lighting panels, control cabinets, and branch distribution boards, especially in buildings where everything is laid out cleanly on DIN rail for easier maintenance and future changes.
It’s rated for 277VAC applications with a 14kA interrupting capacity, which makes it suitable for typical commercial branch circuit protection. The single-pole design keeps it compact, which is helpful when panel space is limited but circuits still need proper protection.
At its core, this is a simple, familiar breaker—used where the goal is to keep circuits protected without overcomplicating the panel design.
