Three poles, line-protection design, with an undervoltage release (UVR) built in and a communication function for remote monitoring or trip indication. Interrupting capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V, so it handles high-fault utility feeds without cascading upstream.
Power loss is 16 W maximum at rated load — manageable for panel thermal budgeting. Trip indicator is present, and the breaker includes a communication function.
Yes, it comes with a factory-installed undervoltage release (UVR) as part of the auxiliary release design.
