Important Notes

This is an open-style three-phase line reactor, not a standalone drive or power supply.
Confirm the required inductance, current rating, system voltage, and installation configuration before ordering.
The manufacturer's selection documentation notes that two reactors are required in parallel for the specified configuration; verify the application requirements before installation.
