LMD63T500 - 500Amp Trip Unit

LMD63T500 - 500Amp Trip Unit

The LMD63T500 has a few details that make identification fairly straightforward. Start with the basics: 500 amps, three poles, and an LMD frame. TA3K500 lugs are provided on the line and load sides, with a stated wire range of 1/0 AWG through 500 kcmil for copper or aluminum conductors. And before calling it a match, check the footprint. The LMD63T500 measures 7.5" W × 16" H × 4.5"D. Those are the details that matter when you have an existing breaker or piece of legacy equipment in front of you. Match the frame, amperage, poles, trip arrangement, interrupting capacity, lugs, wire range, and physical size—not just the catalog number. Properly matched, installed, and maintained within its stated ratings, the LMD63T500 is built to last.

Key Features and Benefits

• 500A, three-pole setup: Two quick specifications to check against the equipment already in service.
• LMD frame: An important part of determining whether the unit belongs in the application.
• Thermal-magnetic trip unit: The trip configuration specified for the LMD63T500.
• Lugs on both sides: TA3K500 lugs are identified for the line and load connections.
• 1/0 AWG–500 kcmil wire range: Covers the manufacturer-specified conductor range for this configuration.
• Cu/Al conductor compatibility: The supplied lug information identifies both copper and aluminum conductors.
• UL and IEC standards: Manufacturer information states that the product meets UL 489 and IEC 60947-2.

Material Compliance and Certifications

The supplied manufacturer specifications state that the LMD63T500 meets UL 489 and IEC 60947-2 standards.

Where It Works Best

The LMD63T500 belongs in compatible existing and legacy equipment that calls for this particular LMD-frame, 500A, three-pole thermal-magnetic configuration. The interrupting ratings match as well. So are the TA3K500 line and load lugs and their 1/0 AWG–500 kcmil Cu/Al wire range.
