Eaton HKD3175W - 175 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton HKD3175W — a rugged 175 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to protect your electrical distribution with precision. Built for dependable branch circuit overcurrent and short-circuit protection, it shines in panelboards and load centers across residential, commercial, and light industrial environments.

Why the HKD3175W stands out

• Secure bolt-on mounting delivers a rigid, vibration-resistant bus connection. By staying firmly fastened through start-up shocks and equipment cycling, it helps maintain consistent electrical continuity and reduces loosening risks.
• Thermal-magnetic trip unit combines slow-developing thermal overload protection with fast magnetic short-circuit interruption. The result is stable, repeatable protection across varying loads and fault conditions, minimizing nuisance trips while safeguarding equipment.
• OEM-compatible design is engineered to integrate seamlessly with matching Eaton OEM load centers and panelboards, ensuring proper fit, alignment, and reliable performance from installation to maintenance.
• Three-pole configuration for three-phase systems supports balanced protection in modern commercial and light industrial panels, helping to coordinate protection across all phases and reduce the risk of unbalanced faults.
• High-current capability in a compact footprint at 175 A with a 600 V rating makes it suitable for mid-size feeders and critical distribution circuits without expanding the panel footprint.

Installation, compatibility, and practical advantages

• Bolt-on mounting simplifies field installation and replacement in compatible Eaton panelboards and load centers, delivering a robust connection that resists vibration and maintains electrical integrity over time.
• Designed for branch-circuit protection against overcurrent and short circuits, helping to guard wiring, devices, and connected loads in everyday commercial and residential applications.
• Reliable performance in varied environments—suitable for spaces where equipment experiences frequent on/off cycling, temperature fluctuations, or routine electrical transients.

Ideal use cases and applications

• Residential and light commercial panelboards where a dependable 3-pole, 175 A protection solution is required for three-phase distribution feeders or critical branch circuits.
• Commercial spaces such as offices, retail outlets, and data/backup rooms that rely on stable protection for power distribution networks.
• Light industrial settings with moderate machinery loads, where durable bolt-on mounting and robust overcurrent protection are essential for uptime.
• Panelboard upgrades or replacements in OEM systems that demand exact-fit compatibility and standard Eaton protection performance.
