Siemens | QJ3B06000S01 | Circuit Breaker | 3-Pole | 240V

Siemens QJ3B06000S01 is a rugged, three-pole circuit breaker designed for reliable overcurrent protection in 240V electrical systems. Built to support maintenance, retrofit, and replacement projects, this device helps keep commercial and industrial panels safe and compliant when upgrading or repairing aging infrastructure.

• Pole configuration: 3-Pole arc-fault protection suitable for multi-phase circuits.
• Voltage rating: 240V, ideal for standard 3-phase or single-phase distribution in compatible panels.
• Part reference: QJ3B06000S01 is the primary identifier for compatibility and ordering.
• Ready for retrofit and replacement: Designed to drop into systems that require matching specifications, minimizing panel downtime.

Why choose this Siemens circuit breaker?

Rather than guessing at compatibility, this model uses a precise part number as the best reference. That means quicker sourcing, fewer compatibility risks, and a smoother replacement process when you’re restoring critical equipment or upgrading control panels.

Ideal use cases

• Maintenance projects where an existing Siemens panel requires a precise, 3-pole, 240V breaker to restore protection.
• Retrofits that involve upgrading older equipment to meet current safety standards without changing the panel layout.
• Replacement scenarios where the QJ3B06000S01 specification matches the original device, ensuring consistent protection characteristics.

Practical guidance for buyers

• Always confirm fit and ratings before ordering. Use the part number QJ3B06000S01 as the primary compatibility reference.
• Plan for quick replacements by keeping a spare 3-Pole, 240V breaker on hand for panels that rely on Siemens components.
• When integrating into existing systems, verify electrical code compliance and panel compatibility to avoid unnecessary downtime.

With Siemens QJ3B06000S01, you gain a dependable, precisely specified circuit breaker designed to protect multi-phase 240V circuits while streamlining maintenance and retrofitting workflows. Trust in a part-number-driven approach to ensure accurate fit, reliable performance, and safer electrical operation across your equipment and facilities.
