LMD63T800 - 800Amp Trip Unit Description
LMD63T800 - 800Amp Trip Unit
The most important words in the LMD63T800 description are "trip unit only." This catalog number identifies the thermal-magnetic trip unit for an LMD-frame application; do not confuse it with a complete molded case circuit breaker assembly. Manufacturer data associates the LMD63T800 with an 800A, three-pole, 600VAC LMD configuration and lists interrupting ratings of 50 kAIC at 480VAC and 25 kAIC at 600VAC. When correctly matched to your intended equipment, properly installed, and maintained within its stated ratings, the LMD63T800 is built to last.
Key Features and Benefits
- Trip-unit-only configuration: The manufacturer identifies the LMD63T800 as "TU ONLY," so it should not be treated as a complete breaker assembly.
- 800A rating: Intended for the manufacturer-specified 800A LMD configuration.
- LMD frame application: Designed as a thermal-magnetic trip unit for an LMD frame.
- Three-pole configuration: Manufacturer data associates this trip unit with a three-pole breaker arrangement.
- Thermal-magnetic trip design: An essential functional detail when matching the unit to existing LMD equipment.
- Referenced TA3K500 lug arrangement: Product data references TA3K500 lugs on the line and load sides. Because this SKU is trip-unit-only, confirm the components supplied with the exact item.

Where It Works Best
The LMD63T800 800A thermal-magnetic trip unit is intended for compatible existing and legacy equipment requiring the corresponding LMD-frame trip-unit configuration. The TU ONLY designation deserves particular attention here. If you need a complete breaker assembly rather than the trip unit, do not assume this catalog number provides it.
