Iso Busbar Adapters
• Two-part construction
- Device Adapter Plate (DAP) (carrying the starter) snaps onto the base adapter
- Base adapter remains on busbar when exchanging starters, providing isolation from live parts
• Test position with load circuit isolated
• Optional control plug makes the starter fully pluggable
• Adapters with assigned current ratings supply the load current to the starter/load feeder by means of wire connections
• Multiple adapters can be combined to bigger platforms by use of the connection clips
• Fits on 5 mm (0.19 in.) or 10 mm (0.39 in.) thick busbars
• Meets UL 508A feeder circuit spacing requirements
