Siemens BQD330 30A 3P 480V Bolt-On Circuit Breaker is a purpose-built protection solution designed for reliable, code-compliant distribution in panelboards, load centers, and electrical distribution networks. With a 30-amp rating across three poles and a 480V operating capacity, this breaker is tailored for balanced three-phase circuits in commercial and industrial settings.
What makes the BQD330 stand out is its bolt-on mounting, which delivers a secure, straightforward installation that’s ideal for retrofit work and maintenance planning. When project requirements call for keeping the same part number, the BQD330 provides a consistent, predictable replacement path that minimizes downtime and ensures compatibility with existing Siemens infrastructure.
- Bolt-on mounting for fast, reliable installation and solid electrical connections.
- Three-pole design protecting three-phase circuits with precise, coordinated switching.
- 30 A, 480V rating suitable for higher-voltage distribution in panelboards and load centers.
- Part Number consistency (BQD330) supports streamlined spares management and easier specification in retrofit projects.
- Ideal for retrofit and maintenance when keeping a consistent Siemens part number reduces risk and downtime.
- Available from AmpState with support to confirm fit and ensure the right match for your panel.
Who it's for: maintenance teams, electrical engineers, facilities managers, and system integrators working with Siemens panelboards and distribution systems will appreciate the predictable fit, reliable protection, and efficient service life the BQD330 offers.
Practical tips: verify that your panel supports bolt-on breakers in the Siemens BQD line, confirm that the bus stabs and mounting footprint align with the BQD330, and keep a spare unit on hand for planned outages. If you’re unsure about compatibility, our team can help confirm fit based on the part number and application.
