CQD230 - 30Amp Circuit Breaker
The CQD230 Siemens CQD miniature circuit breaker is a 30 Amp, 2-pole breaker used in real-world commercial and industrial panel setups where 480/277V circuits need reliable, everyday protection. You’ll usually find it inside lighting panels, control cabinets, and distribution boards, especially in buildings built around DIN rail layouts, which keep wiring organized and easy to follow during maintenance.
It’s rated for 480/277VAC systems with a 14kA interrupting capacity, making it a common choice for standard branch-circuit protection in commercial environments. The 2-pole design disconnects both conductors together, which is typically required for 277/480V lighting and distribution circuits.
At the end of the day, this is a practical, no-fuss breaker that fits into systems where you need proper protection, consistent fit, and easy replacement without changing the panel layout.
