Open Circuit (Three-Phase)
Three-phase terminator that draws no current
Simscape / Electrical / Connectors & References
The Open Circuit (Three-Phase) block models a three-phase connection that draws no current on any of the three phases.
Modeling option — Whether to model composite or expanded three-phase ports
Composite three-phase ports (default) |
Expanded three-phase ports
Whether to model composite or expanded three-phase ports.
Composite three-phase ports represent three individual electrical conserving ports with a single block port. You can use composite three-phase ports to build models that correspond to single-line diagrams of three-phase electrical systems.
Expanded three-phase ports represent the individual phases of a three-phase system using three separate electrical conserving ports.

R2019b: Capping unconnected ports is no longer required
This block is no longer required. Starting in R2019b, the restriction that disallowed unconnected conserving ports in Simscape™ models has been lifted. Now, if you leave a conserving port unconnected, the physical network sets all the Through variables at this port to 0. However, you can still use terminator blocks to improve diagram readability.
There are no plans to remove the terminator blocks. All the existing models using these blocks work the same as in previous releases.
