HLD3600 - 600Amp Circuit Breaker

HLD3600 - 600Amp Circuit Breaker

When you’re replacing a circuit breaker in existing equipment, getting the details right matters. The Eaton HLD3600 is a 600A, 3-pole molded-case circuit breaker from the Series C HLD family, built on an L-frame. It carries voltage ratings of 600 Vac and 250 Vdc, uses a T186 trip type, and operates at 50–60 Hz. Interrupt ratings are 100 kAIC at 240 Vac and 65 kAIC at 480 Vac. The breaker also comes with aluminum line and load terminals and is UL Listed.

Key Features and Benefits

• 600A, 3-pole configuration – Designed for applications requiring a 600 amp, three-pole molded case circuit breaker.
• Series C HLD construction – Uses Eaton’s HLD configuration with an L frame for compatible equipment.
• AC and DC voltage ratings – Rated for 600 Vac and 250 Vdc applications.
• T186 trip type – Matches applications designed around this specific trip configuration.
• Complete breaker – Supplied as a complete molded case circuit breaker rather than an individual breaker component.
• Line and load terminals – Equipped with aluminum terminals on both sides.
• UL Listed – Carries UL certification for applicable installations.

Material Compliance and Certifications

The HLD3600 is UL Listed and uses aluminum line and load terminals. Its published electrical specifications include a 600A rating, a three-pole configuration, a 600 Vac/250 Vdc voltage rating, a T186 trip type, and a 50–60 Hz frequency rating.

When matching this breaker to existing equipment, don’t stop at the amperage rating. Check the complete set of specifications—including frame, number of poles, voltage, trip type, terminals, and interrupt capacity—to determine whether the HLD3600 is the correct fit for the application.

Where It Works Best

The Eaton HLD3600 makes the most sense in existing electrical equipment designed for the Series C HLD L-frame breaker configuration. That makes it particularly relevant for maintenance, repair, and replacement situations where maintaining the required form, fit, and function is the priority.

For a proper match, the existing application should be checked for its 600A rating, three-pole arrangement, L-frame, T186 trip type, 600 Vac/250 Vdc voltage requirements, aluminum line and load terminals, and required interrupt capacity.
