Siemens FXD62B110L - 110 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Siemens FXD62B110L is a purpose-built 110-amp, 600-volt, 2-pole bolt-on molded case circuit breaker designed to protect your electrical distribution with precision. Built for dependable branch circuit overcurrent and short-circuit protection, it integrates seamlessly into panelboards and load centers that require a secure, rugged protection solution.

Key advantages that matter in real-world panels

• Secure bolt-on mounting: A rigid connection to the bus minimizes movement and vibration, helping prevent loosening and ensuring consistent performance even in environments with vibration or frequent panel access.
• Thermal-magnetic trip unit: The combination of thermal and magnetic sensing delivers stable, repeatable protection for both prolonged overloads and sudden short circuits, reducing nuisance trips and safeguarding connected equipment.
• OEM-compatible design: Specifically crafted to work with matching Siemens OEM load centers and panelboards, delivering reliable fit, alignment, and tripping behavior that installers trust.
• Versatile application: Suitable for residential, commercial, and light industrial settings, making it a practical choice for new installations, panel upgrades, or replacing a failing breaker in existing Siemens-based systems.

What this breaker protects and where it shines

The FXD62B110L safeguards branch circuits from overcurrent and short-circuit events, helping to prevent wiring damage, insulation failure, and fire risks. Its 2-pole configuration is ideal for 240V circuits commonly used in dryers, water heaters, air conditioning systems, and other multi-wire branch circuits within panelboards and load centers.

Why choose this model over generic equivalents

When you select the Siemens FXD62B110L, you’re choosing a solution engineered to align with Siemens panelboard and load center architectures. The bolt-on mounting method not only provides a solid mechanical connection but also enhances long-term reliability in installations that experience vibration, temperature swings, or regular panel maintenance. The thermal-magnetic trip mechanism offers predictable protection curves, helping you plan safe shutdowns and reduce the risk of unexpected equipment downtime.

Ideal use scenarios

• Upgrading or replacing a failed breaker in Siemens panelboards where bolt-on installation is specified
• Protecting critical 240V circuits in light commercial spaces, such as small offices, retail fixtures, or service equipment
• Enclosures and load centers that require a robust, vibration-resistant connection in variable environments
