This Siemens SIRIUS busbar device holder (model 8US19232AA01) offers a direct-mount solution for integrating SIRIUS 3RV2 circuit breakers, 3RT2 contactors, or 3RA2 load feeders onto an 8US busbar system. Unlike generic adapters, it provides both mechanical support and electrical connection in one compact unit, streamlining panel assembly and reducing wiring effort.

Highlights

• Direct mounting on Siemens 8US busbar system
• Compatible with SIRIUS 3RV2, 3RT2, and 3RA2 devices
• High-grade insulating plastic construction for safety and durability
• Rated insulation voltage 690 V, impulse withstand 6 kV
• Operating temperature range -25 to +60 °C

In daily use

The holder snaps onto the busbar and accepts the device without additional adapters, ensuring a secure fit and reliable electrical contact. Its dark grey/black finish blends into industrial control cabinets, and the insulating plastic reduces risk of accidental contact. Suitable for pollution degree 3 environments, it withstands demanding conditions in power distribution and motor control applications.
