Siemens BQD6230 - 30 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens BQD6230 is a 30A, 600V, 2-pole bolt-on molded case circuit breaker engineered for dependable branch-circuit protection in panelboards and load centers. Built to withstand vibration and demanding electrical environments, this unit delivers consistent performance where reliability matters most.

Key features that improve your electrical reliability

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing contact wear and maintaining stable current flow in dynamic installations.
• Thermal-magnetic trip unit combines steady thermal protection with magnetic instantaneous response for fast, repeatable protection against overloads and short circuits.
• OEM-compatible design ensures seamless pairing with matching Siemens load centers and panelboards, promoting coordinated protection and straightforward replacement.
• Versatile application range suitable for residential, commercial, and light-industrial panel systems that require reliable 600V branch-circuit protection.

How this breaker protects your system

The 2-pole configuration safeguards both conductors in multi-wire circuits, reducing the risk of backfeed and improving overall safety. A 30A rating is well-suited for branch circuits feeding lighting, small equipment, control circuits, or modest motor loads within a panelboard. The 600V rating expands its usefulness in commercial or light-industrial distribution, providing a single, dependable solution across varying projects.
