Where It Works Best

The LD3500L is most relevant when you're maintaining compatible existing or legacy equipment that requires a 500A, 3-pole Type LD thermal-magnetic breaker.

A few things are worth checking closely before making the match. First, confirm the system voltage and required interrupting capacity against the breaker's 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC ratings. Then confirm whether the application requires an interchangeable trip unit and the supplied line-and-load terminal configuration.
