Where HVPB blocks fit
Marathon's standard open and stud power blocks are rated up to 600 V. A 1500 VDC string in a BESS rack, a solar combiner or a DC bus in a data center needs a block listed for 1500 V. Pick the block by the feeder amps, then by the line side conductor or stud, then by how many load taps you need per pole. Send that and we will pick the catalog number with you.
See Marathon Special Products for data centers and BESS, the Marathon collection or the cross reference hub.
