Eaton HLD3500W - 500 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Protect critical electrical paths with the Eaton HLD3500W—a 3-pole, 500 A, 600 V bolt-on molded case circuit breaker designed for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built to withstand real-world vibrations and demanding loads, this breaker keeps power flowing safely in residential, commercial, and light industrial environments.

• Secure bolt-on mounting: delivers a rigid, vibration-resistant bus connection that stays tight under heavy use and in busy electrical spaces, reducing the risk of loose connections and nuisance trips.
• Thermal-magnetic trip unit: combines precise thermal overload protection with immediate magnetic tripping for sudden short-circuit events, delivering stable, repeatable protection performance across a wide range of operating conditions.
• OEM-compatible design: engineered to integrate smoothly with matching Eaton OEM load centers and panelboards, ensuring a cohesive, reliable protection system without custom adapters.
• Versatile, ready for demanding applications: ideal for residential panels that require robust protection, commercial electrical rooms with higher fault currents, and light industrial installations needing dependable main-branch circuit safeguarding.

Why the Eaton HLD3500W makes a difference

In everyday use, this MCCB (molded case circuit breaker) helps prevent electrical damage and downtime by interrupting fault currents quickly while maintaining steady protection during normal operation. The 3-pole configuration supports balanced, three-phase circuits where high current handling and reliable trip behavior are essential. With its bolt-on mounting, technicians gain a solid, low-impedance connection that resists loosening from vibration or thermal cycling—a critical advantage in busy panels and compact spaces.

Use cases and ideal candidates

• New installations or panel retrofits in commercial spaces requiring 600 V class protection and 500 A main/branch protection.
• Residential and light industrial panels that demand durable, high-current protection with straightforward bolt-on installation.
• Systems where OEM compatibility and ease of replacement are priorities to minimize downtime and compatibility issues.
