LD3600L - 600Amp Circuit Breaker

LD3600L - 600Amp Circuit Breaker

The LD3600L is a 600-amp, 3-pole Type LD thermal-magnetic circuit breaker with an interchangeable trip unit. It's a solid fit for maintenance and replacement jobs where your existing equipment was designed around this particular LD breaker configuration. When the catalog number, ratings, trip configuration, connections, and physical fit match the application, the LD3600L provides the form, fit, and function needed to keep compatible equipment in service. Properly selected, installed, and used within its specified ratings, it is built to last in its intended application.

Material Compliance and Certifications

The supplied product information identifies the LD3600L as HACR rated. No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided, so do not assume those details.

Where It Works Best

The LD3600L is most relevant when you're working on existing or legacy equipment that specifically requires a 600A, 3-pole Type LD breaker. Rather than choosing a replacement based on amperage alone, compare the full set of specifications with what's already installed.

Start with the system voltage. The corresponding interrupting rating is 25 kA at 600 VAC, 35 kA at 480 VAC, and 65 kA at 240 VAC. The required AIC must match the electrical system.
