Siemens FXD62B225 - 225 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Siemens FXD62B225 is a 225 A, 600 V, 2-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Available through AmpState, this unit combines Siemens reliability with a rugged bolt-on mounting for a solid, vibration-resistant bus connection and precise protection performance.

Key Features and Benefits

• Secure bolt-on mounting: Ensures a rigid, vibration-resistant bus connection that stays tight in demanding electrical environments.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by providing thermal protection for overloads and magnetic protection for short circuits.
• OEM-compatible: Designed to pair with matching Siemens OEM load centers and panelboards for seamless replacement and coordinated protection schemes.
• Versatile application: Ideal for residential, commercial, and light industrial installations needing reliable 2-pole protection up to 600 V.

Technical Snapshot

• Amperage rating: 225 A
• Voltage rating: 600 V
• Number of poles: 2
• Mounting style: Bolt-on
• Type: Thermal-magnetic molded case circuit breaker
• Primary application: Branch circuit overcurrent and short-circuit protection

Practical Use Cases

• New installations in panelboards and load centers that require reliable 2-pole protection at 225 A and up to 600 V.
• Retrofits or replacements in Siemens-compatible OEM panels where a sturdy, bolt-on breaker is preferred for long-term performance.
• Industrial or commercial environments with equipment vibration, where a secure bus connection minimizes connection looseness and related faults.
• Residential or light-industrial service panels needing predictable trip behavior and coordinated protection across multiple circuits.

Why This FXD62B225 Stands Out

Beyond the obvious specifications, this breaker is engineered for real-world durability and dependable protection. The bolt-on design reduces the risk of loose connections that can lead to arcing, while the thermal-magnetic trip unit provides consistent response across load conditions. Its compatibility with matching OEM panels makes it a practical, maintenance-friendly choice for electricians and facility managers who value reliability and streamlined service life.

installation and Compatibility

• Confirm your panelboard or load center is designed to accept Siemens FXD62B225 bolt-on breakers.
• Follow standard electrical safety practices during installation and refer to Siemens installation guidelines for proper mounting.
• Utilize the FXD62B225 when you need a high-current, 2-pole solution with robust protection for critical branch circuits.
