Eaton KD3150X - 150 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton KD3150X is a rugged, three‑pole molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and loadcenters. Rated for 150 A and 600 V, this bolt‑on unit is built to stand up to demanding commercial and light industrial environments while keeping residential systems safe and compliant.

• Secure bolt‑on mounting ensures a rigid, vibration‑resistant bus connection, reducing movement and maintaining consistent electrical contact even in harsh installation locations.
• Thermal‑magnetic trip unit combines precise thermal overload protection with instantaneous magnetic trip for fast, repeatable fault clearance across a range of temperatures and loads.
• Three‑pole design provides reliable protection for 3‑phase systems, making it ideal for commercial and light industrial panelboards and loadcenters.
• High current and voltage ratings — 150 A holding capacity at 600 V enable protection for sizable feeders and main distribution lines while meeting electrical codes and safety standards.
• OEM‑compatibility with matching Eaton load centers and panelboards ensures proper fit, alignment, and predictable performance within existing protection schemes.
• Versatile applications suitable for residential, commercial, and light industrial settings, from service entrances and subpanels to equipment feeders and distribution boards.

Why choose the Eaton KD3150X? This breaker delivers a tangible, real‑world advantage: a secure, vibration‑tolerant connection combined with reliable, repeatable protection that minimizes nuisance trips and ensures quick fault isolation. Its bolt‑on design is especially beneficial in installations where panel rigidity, long‑term contact reliability, and ease of service are priorities.

Use cases and scenarios

• Upgrading a commercial loadcenter to support higher feeder demands without compromising protection reliability.
• Integrating into 3‑phase panelboards in light industrial environments where equipment uptime matters.
• Replacing aging breakers in residential‑scale 3‑pole panel systems to restore robust overcurrent protection.
