Siemens | BQD33000S01 | Circuit Breaker | 30A | 3-Pole | 480V | Bolt-On

Meet the Siemens BQD33000S01 Circuit Breaker—a purpose-built protection device designed for demanding industrial 3-phase, 480V systems. With a robust 30A rating and a true 3-pole configuration, this bolt-on breaker is engineered for reliable, secure disconnection in maintenance, retrofit, and replacement projects. If you’re aligning with exact Siemens specifications, this part number (BQD33000S01) is your best reference for compatibility and performance.

• Amperage: 30A — precise current protection tailored for moderate-to-high load circuits.
• Poles: 3-Pole — ideal for three-phase power distribution, ensuring simultaneous shutoff of all live conductors.
• Voltage rating: 480V — designed for standard industrial 3-phase systems.
• Mounting style: Bolt-On — provides a secure, vibration-resistant installation in compatible Siemens panels.
• Part reference: BQD33000S01 — use this exact part number to confirm kit compatibility and panel fit.

Why this Siemens breaker stands out

Instead of a generic replacement, the BQD33000S01 is built to match Siemens’ bolt-on family specifications, delivering predictable performance in maintenance and retrofit scenarios. Its 3-pole design ensures all phases are tripped together, reducing the risk of arc flash or unequal loading during fault conditions. The bolt-on mount enables a solid connection in compatible enclosures, which helps minimize looseness and vibration in busy industrial environments.

Ideal applications and use cases

Designed for 3-phase equipment and distribution panels that operate at nominal 480V, this breaker is well-suited for:

• Industrial machinery and conveyors powered by 480V three-phase systems
• Motor control circuits and feeders in retrofit projects
• Replacement on Siemens panels that accept BQD-series bolt-on breakers
• Maintenance outages where a precise, compatible breaker is required to restore safe operation

Installation and compatibility notes

Before ordering, confirm fit and ratings to ensure seamless replacement. The BQD33000S01 is intended for Siemens panels that accept bolt-on breakers in the 3-pole, 480V category. Use the exact part number as the reference for compatibility, and verify that the panel labeling matches a 30A, 3-pole, 480V bolt-on device.

Practical guidance for best results

• Plan replacements during de-energized, locked-out maintenance windows to ensure safety and compliance.
• Cross-check the panel’s documented compatibility with BQD bolt-on breakers to avoid mounting or electrical issues.
• Label the circuit clearly after installation to reflect the correct protection parameters and maintenance history.
