Eaton | LD3500Y | Circuit Breaker | 500A | 3-Pole | 600V

Meet the Eaton LD3500Y circuit breaker—a rugged, high-capacity protection device built for demanding industrial power systems. With a 500A current rating, a 3-pole configuration, and a 600V rating, this breaker is designed to reliably safeguard three-phase circuits in commercial and industrial environments. It’s an ideal choice for maintenance, retrofit, and replacement projects where exact specifications matter.

Key specifications

• Amperage: 500A
• Poles: 3-Pole
• Voltage: 600V
• Part reference: LD3500Y

Why choose the Eaton LD3500Y for your panel

• : Use the LD3500Y part number as the primary reference to ensure a correct fit with your existing Eaton infrastructure or compatible panels.
• Robust three-phase protection: The 3-pole design provides synchronized disconnection across all phases, helping prevent unbalanced loads and reducing the risk of damaged equipment on startup or fault events.
• High-current reliability: Rated for 500A, it supports heavy feeders and main-distribution links in demanding environments where consistent protection is essential.
• Versatile for retrofit and replacement: Ideal for upgrading legacy systems, replacing worn breakers, or refreshing power distribution in facilities undergoing modernization.
• Clear fitment guidance: Before ordering, confirm fit and ratings; the part number is your best reference to maintain system integrity and uptime.

Use cases and practical applications

• Main service disconnects in commercial or industrial electrical panels, where a single, reliable 500A breaker is required to protect downstream equipment.
• Retrofit projects upgrading older 3-phase systems to meet current protection standards while maintaining existing panel footprints.
• Replacement scenarios where a failed or outdated 3-pole 600V breaker needs to be swapped in without changing other components.
• Facilities targeting improved power distribution reliability in manufacturing floors, data centers with heavy equipment loads, or large HVAC and pumping systems.

Installation and safety notes

Because project requirements vary, ensure you have the correct panel compatibility and ratings before installation. Engage a qualified electrician to verify electrical clearances, proper torque for terminals, and adherence to all relevant safety standards. Keep in mind that the LD3500Y is intended for use with systems operating at up to 600V and 500A—the panel and conductors must be rated accordingly.
