LDB3350 - 350Amp Circuit Breaker Description
LDB3350 - 350Amp Circuit Breaker
The LDB3350 is a 350-amp, 3-pole molded-case circuit breaker for applications that require a Type LDB, L-Frame configuration. Its thermal-magnetic design uses a non-interchangeable trip unit, an important distinction when you're matching a breaker to existing equipment. When the frame, ratings, trip configuration, connections, and physical dimensions match the application, the LDB3350 can serve as a form, fit, and functional replacement.

Material Compliance and Certifications
The supplied specifications identify the LDB3350 as HACR-rated.
No specific UL, CSA, IEC, RoHS, REACH, or other material-compliance or certification details were provided for this catalog number, so do not assume them. Where a particular listing or certification is required, confirm it from the markings on the actual breaker and the documentation for the equipment in which it will be installed.
Where It Works Best
The LDB3350 makes the most sense in existing or legacy electrical equipment that specifically requires a 350A, 3-pole Type LDB L-Frame molded case circuit breaker with a non-interchangeable thermal-magnetic trip unit.
Pay close attention to the interrupting capacity required by the installation. The LDB3350 is specified at 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC. The applicable rating must meet the equipment requirements and the available fault current at the installation.
