ISO Busbar Modules
- 2-part construction
- Device Adapter Plate (or DAP) (carrying the starter) snaps onto the base of the module
- Base module remains on busbar when exchanging starters, providing isolation from live parts
- Device Adapter Plate (or DAP) (carrying the starter) snaps onto the base of the module
- Test position with load circuit isolated
- Designed for use with control plug (order separately)
- Modules with current ratings supply the load current by means of wire connections matched to Bulletin 140-M motor protection circuit breakers
- Modules can form bigger platforms using the connection clips (see accessories)
- For plugging on 5 mm or 10 mm thick busbars
- Meets feeder circuit spacings per UL 508A
