Siemens | B140HH00S01 | Circuit Breaker | 40A | 1-Pole | 240V | Bolt-On

Siemens delivers a precise, bolt-on circuit protection solution with the B140HH00S01. This 40A, 1-pole breaker is engineered for reliability in maintenance, retrofit, and replacement projects, ensuring your panel maintains its intended performance and safety profile when a matching spec is required.

• Amperage: 40 A
• Poles: 1-Pole
• Voltage: 240 V
• Mounting: Bolt-On

Why this Siemens breaker matters

Choosing the exact Siemens B140HH00S01 part eliminates guesswork in your electrical system. A proper match for panels designed to accept bolt-on, single-pole breakers at 240 volts means consistent trip characteristics, compatibility with the panel’s bus design, and safer, more predictable operation during fault conditions. This is not a generic replacement—it’s a purpose-built component that aligns with Siemens engineering standards and your panel’s original specifications.

Compatibility and installation considerations

Notes to keep in mind: confirm fit and ratings before ordering. The B140HH00S01 part number is the best reference when evaluating compatibility with your specific Siemens panel. This bolt-on configuration is intended for panels that explicitly support bolt-on, single-pole, 240V devices. If your panel uses a different mounting system or requires a different amperage or pole count, this unit may not be the correct match.

Ideal use cases

• Retrofit projects where the panel requires a 40 A, 1-pole, 240 V bolt-on breaker
• Replacement of a failed unit in compatible Siemens panels to restore proper protection
• Maintenance upgrades that demand a precise reference part to maintain panel integrity

Practical guidance for safe handling

Handle with the power off and follow standard electrical safety practices. Keep the part number and documentation handy to verify compatibility in future service calls. If you’re unsure about panel compatibility or installation steps, consult a licensed electrician to ensure a safe, code-compliant setup.
