Siemens FXD62B080 - 80 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Siemens FXD62B080 is a robust, 2-pole bolt-on molded-case circuit breaker engineered to shield branch circuits from overcurrent and short-circuit events. Rated for 80A and up to 600V, this unit is built to perform reliably in panelboards and load centers across residential, commercial, and light industrial environments.

• Secure bolt-on mounting: provides a rigid, vibration-resistant connection to the bus, reducing loosening risks in busy electrical panels.
• Thermal-magnetic trip unit: delivers stable, repeatable protection by responding to both overloads (thermal) and short circuits (magnetic) with predictable tripping characteristics.
• 2-pole, 80A, 600V rating: suits a wide range of circuits while preserving safe, coordinated protection in multi-wire setups.
• OEM-compatible: designed to be compatible with Siemens OEM load centers and panelboards for straightforward replacement and consistent performance.
• Versatile across sectors: ideal for residential feeders, commercial lighting and outlets, and light industrial equipment protection.

Why this breaker is a smart choice

Beyond its specs, the FXD62B080 brings reliability and maintenance-friendly service to your electrical distribution. The molded-case construction helps contain arc energy and supports long-term durability in panel environments. The thermal-magnetic trip unit gives you predictable protection across temperature swings and varying load conditions, making it easier to design safe, code-compliant electrical systems.

Use cases and tips

• Primary protection for branch circuits in residential panelboards and subpanels.
• Protection for lighting circuits, outlets, and small equipment in commercial spaces.
• Protection for light industrial circuits where dependable, fast-tripping protection is required.
• When replacing a breaker, verify compatibility with your Siemens panelboard and ensure proper torque and enclosure clearance during installation.
