This lot, SB62, is a Kinney Electrical Systems main distribution panel (MDP1) constructed in December 2022 for a modern high-demand electrical installation.
The unit is rated 4000 amps continuous, 480/277 V, 3-phase, 4-wire, and 600 V max.
The switchboard features a Square D MasterPact MTZ2-30H main breaker with Micrologic trip unit, two PowerPact PJ 1200 A feeders, a 3000 A feeder ATS, and an integrated SurgeLogic surge protective device (SPD) mounted on the main service breaker.
This system represents a current-production Square D architecture with Micrologic intelligence for metering, protection, and communication.
It was engineered and installed by Kinney Electrical Systems as part of a premium power distribution package for a commercial/industrial CEA facility and remains in excellent condition.
