LD3500 - 500Amp Circuit Breaker

LD3500 - 500Amp Circuit Breaker

The LD3500 is a 500-amp, 3-pole Type LD thermal-magnetic circuit breaker with an interchangeable trip unit. If you're matching a breaker for equipment already in service, consider these details. The LD3500 makes the most sense when you need a 500A Type LD breaker with this specific electrical and physical configuration. Properly matched to the equipment, installed correctly, and kept within its specified ratings, it's built to last for its intended application.

Material Compliance and Certifications

Available information identifies the LD3500 as HACR-rated. Specific UL, CSA, IEC, RoHS, REACH, or other certification and material-compliance details were not provided, so do not assume them.

Where It Works Best

The LD3500 is geared toward maintenance and replacement work where existing or legacy equipment requires a 500A, 3-pole Type LD thermal-magnetic circuit breaker.

For a replacement match, check the system voltage against the corresponding interrupting rating: 25kA at 600VAC, 35kA at 480VAC, or 65kA at 240VAC. You'll also want to confirm that an interchangeable trip unit is appropriate for the application.
