Siemens | HFD62B100L | Circuit Breaker | 100A | 2-Pole | 600V

Siemens HFD62B100L Circuit Breaker — a precise, purpose-built solution for maintenance, retrofit, and replacement projects that require exact specs. This 100A, 2-Pole unit is rated up to 600V, delivering reliable, coordinated protection across multi-wire circuits.

Key details:

• Amperage: 100 A
• Poles: 2-Pole
• Voltage rating: 600 V
• Part reference: HFD62B100L (best compatibility reference)
• Intended use: maintenance, retrofit, and replacement where matching specs are required

Why this matters:

• Two-pole design ensures both hot legs are interrupted simultaneously, a crucial safety feature for 240V circuits and shared neutrals.
• Using the exact part number helps prevent misfits in Siemens-load centers and panels, reducing the risk of nuisance trips or improper fit.
• 600V rating expands its applicability to feeders and branch circuits in environments where Siemens breakers are the chosen standard.

How to use and verify compatibility:

• Before ordering, verify compatibility by matching the part number (HFD62B100L) with your panel label and service documentation.
• Check the panel model and bus-stab configuration to ensure this two-pole device will physically and electrically fit.
• Consider the existing system load and protection strategy to confirm that 100 A is the correct protection level for the circuit you’re protecting.

Use cases and ideal scenarios:

• Replacing a blown or aging 2-pole breaker in Siemens-compatible distribution panels or load centers.
• Upgrading a circuit to handle higher demand without changing the entire panel, while keeping coordinated protection across both conductors.
• Retrofit projects where exact spec matching is essential to maintain code compliance and electrical safety.

In short, the Siemens HFD62B100L delivers dependable two-pole overcurrent protection at 100 A and 600 V, backed by the engineering standards that power professional electrical installations. Use the exact part number for ordering to ensure compatibility and a smooth retrofit or replacement experience.
