LD3600 - 600Amp Circuit Breaker

LD3600 - 600Amp Circuit Breaker

The LD3600 is a 600-amp, 3-pole Type LD thermal-magnetic circuit breaker with an interchangeable trip unit. For maintenance work, the important question is whether it matches the equipment already in place. Here, you have the key numbers to make that comparison: 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC, plus a 40°C rating and HACR rating. The breaker also includes load terminals. When properly matched to the equipment, installed correctly, and used within its stated ratings, it's built to last in its intended application.

Material Compliance and Certifications

The information provided identifies the LD3600 as HACR-rated. No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance details were supplied for this product, so don't assume them.

Where It Works Best

The LD3600 is best considered for existing or legacy electrical equipment designed around a 600A, 3-pole Type LD breaker. It's particularly relevant when you're trying to maintain the original form, fit, and function of equipment already in service.

Start with the electrical requirements. At 600 VAC, the interrupting rating is 25 kA. It increases to 35 kA at 480 VAC and 65 kA at 240 VAC. The rating must meet the installation requirements for the actual system voltage.
