KA3125W | Circuit Breaker | 125A | 3-Pole | 600V

KA3125W is an industrial circuit breaker engineered for reliable three-phase protection in demanding environments. With a 125A rating and a 3-pole configuration, this unit is tailored for maintenance, retrofit, and replacement projects where exact specifications matter. The part number KA3125W serves as the clearest compatibility reference, helping you swap in or upgrade without guesswork in your panel or switchgear.

Key specifications

• Amperage: 125A
• Poles: 3-Pole
• Voltage: 600V

Why this KA3125W matters

• Three-phase protection in one device: The 3-pole design ensures synchronized shutoff across all phases, safeguarding motors, drives, and other three-phase equipment.
• Mid-range industrial capacity: A 125A rating supports a broad spectrum of industrial loads while fitting common panel configurations.
• Clear compatibility for retrofits: Rely on the KA3125W part number to match footprint, electrical characteristics, and performance with your existing gear—reducing installation delays.

Ideal use cases

• Replacing a failed breaker in established three-phase panels or switchgear that previously used KA3125W or equivalent 3-pole, 600V units.
• Retrofit projects upgrading older protection schemes to current, compatible specifications without reconfiguring other components.
• Maintenance cycles where consistent spare parts stock is essential to minimize downtime.

Practical guidance for installation and ordering

Before placing an order, confirm that the fit and ratings align with your system. The part number KA3125W is your most reliable reference for compatibility, so double-check panel labeling, busbar connections, and related protection requirements. If your project involves a three-phase distribution network at up to 600V with a 125A load, this breaker is designed to fit seamlessly into the existing protection scheme.
