Eaton | HLDB3500Y | Circuit Breaker | 500A | 3-Pole | 600V

Introducing the Eaton HLDB3500Y circuit breaker, a purpose-built solution for robust overcurrent protection in high-demand electrical systems. Engineered for maintenance, retrofit, and replacement tasks, this 3-pole breaker delivers reliable, consistent performance in installations requiring a 500A rating and 600V operation.

Key specifications

• Amperage: 500 A
• Poles: 3-Pole (three-phase protection)
• Voltage rating: up to 600 V
• Reference part number: HLDB3500Y — use this to verify compatibility with your Eaton panels and equipment

Why this matters

In a three-phase power system, precise trip coordination and reliable fault isolation are critical. The HLDB3500Y is designed to plug into Eaton-compatible installations, offering seamless integration with existing protection schemes. Its 500A rating makes it suitable for feeder circuits and motor-start applications where high current handling is essential.

What makes it stand out

• Exact compatibility: The HLDB3500Y is the best reference for matching Eaton equipment—minimizing the guesswork during maintenance or replacements.
• Strategic for retrofits: When upgrading panels or replacing aging breakers, this unit preserves electrical topology and protective coordination.
• Durable installation path: Designed for straightforward replacement in appropriate Eaton systems, reducing downtime and risk during service windows.

Practical use cases

• Maintenance and repair of existing Eaton distribution panels in warehouses, manufacturing floors, and data centers.
• Retrofit projects where a 500A, 3-pole, 600V protective device is required to restore or upgrade protection without changing the panel family.
• Replacement scenarios that demand exact spec matching to avoid compatibility gaps and ensure continued safe operation.

Important compatibility note

Always confirm fit and ratings before ordering. The part number HLDB3500Y is the most reliable reference for compatibility with your Eaton equipment, ensuring you get the right trip characteristics and mounting fit for your panel lineup.
