Siemens BQD230 - 30 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens BQD230 — 30A, 480V, 2-pole bolt-on circuit breaker. Available from AmpState, this molded case breaker is engineered to deliver dependable branch‑circuit overcurrent and short‑circuit protection in panelboards and load centers.

Proven protection for demanding electrical environments

• Secure bolt-on mounting provides a rigid, vibration‑resistant bus connection that stays solid through operation and transport.
• Thermal‑magnetic trip unit delivers stable, repeatable protection performance and fast fault clearing when it matters most.
• 2-pole design enables simultaneous protection of two conductors with a common trip, enhancing safety and reliability.
• OEM‑level compatibility designed to be used with matching Siemens OEM load centers and panelboards for a seamless fit and straightforward replacement.
• Versatile applications suitable for residential, commercial, and light industrial uses where reliable 30A at 480V protection is required.

How this solves real-world problems

For service panels and distribution boards that experience routine vibration, temperature fluctuations, or occasional nuisance trips, the BQD230’s bolt‑on mount and thermal‑magnetic mechanism provide durable, predictable protection. Its 480V rating makes it appropriate for higher‑voltage branch circuits, while the 2‑pole configuration ensures coordinated disconnection across both conductors—reducing the risk of hazardous fault conditions and improving uptime in electrical systems.
