HLD3500 - 500Amp Circuit Breaker

HLD3500 - 500Amp Circuit Breaker

When you need an Eaton HLD3500 for an existing electrical system, getting the specifications right matters. This Series C molded case circuit breaker is a 500 amp, three-pole HLD breaker built on the L-frame and rated for 600 Vac and 250 Vdc. It has a T186 trip type, operates at 50/60 Hz, and comes complete with aluminum line and load terminals. The frame, voltage, pole configuration, trip type, and interrupt rating must align with the system requirements. The HLD3500 is also UL Listed.

Key Features and Benefits

• 500 amp capacity: Made for applications that specifically call for a 500 A molded case circuit breaker.
• Three-pole design: Provides the pole configuration required by compatible three-phase electrical systems.
• Series C HLD construction: Uses the L-frame configuration associated with the HLD3500.
• AC and DC ratings: Rated at 600 Vac and 250 Vdc.
• T186 trip type: Matches applications designed around this particular trip configuration.
• Complete breaker: Supplied as a complete molded case circuit breaker rather than an individual component.
• Line and load terminals: Aluminum terminals are provided on both sides of the breaker.
• 50/60 Hz operation: Compatible with systems operating at these standard frequencies.

Material Compliance and Certifications

The Eaton HLD3500 is UL Listed and uses aluminum line and load terminals. Its published specifications provide the key information electricians and maintenance professionals need when checking the breaker against existing equipment requirements.

As with any replacement molded-case circuit breaker, don't rely on the 500-amp rating alone. The complete electrical and physical configuration—including voltage, interrupt capacity, frame, number of poles, trip type, and terminal requirements—should match the application.

Where It Works Best

The HLD3500 makes the most sense in existing electrical distribution systems designed for a Series C HLD L-frame 500-amp, three-pole breaker. That makes it especially relevant for maintenance and replacement projects where preserving the original equipment's required form, fit, and function is the goal.
