Square D | KCL34125 | Circuit Breaker | 125A | 3-Pole | 480V | Feed-Through

Introducing the Square D KCL34125: a purpose-built 125A, 3-Pole, 480V feed-through circuit breaker designed for reliable protection and flexible downstream distribution in demanding electrical environments. Built to align with Square D specifications, this unit is ideal for maintenance, retrofit, and replacement projects that require exact matching ratings and form factor.

Key specifications

• Amperage: 125A
• Poles: 3-Pole
• Voltage: 480V
• Configuration: Feed-Through
• Part number reference: KCL34125
• Best use case: Maintenance, retrofit, and replacement where matching specs are required

Why this matters for your system

• Streamlines retrofit and replacement by matching exact Square D specifications in a single device, reducing the need for multiple component changes.
• Feed-through design enables convenient downstream distribution within the same installation, supporting orderly expansion or service upgrades without reconfiguring upstream protection.
• Designed for reliable performance in 480V three-phase networks, ensuring consistent protection across feeders and downstream circuits when the exact 125A, 3-pole, 480V rating is required.

Who should consider it

• Maintenance crews replacing worn or failed breakers in compatible Square D panels
• Facilities planning retrofit projects that require precise, match-rated components for 480V distribution
• Engineers and installers prioritizing compatibility and simplified sourcing with a definitive part reference

Important: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.
