As part of the Siemens SENTRON product line, this LD-frame circuit breaker combines a 600V AC voltage rating, current-limiting breaking capacity, and electronic SensiTrip protection in a configuration designed for equipment requiring these characteristics. When you're maintaining an existing electrical installation, the right breaker is about more than amperage. Frame size, trip functions, interrupting ratings, conductor connections, and physical fit all matter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and
