The UVR ensures the breaker drops out on loss of control power — required for many safety circuits and emergency-stop chains. The trip alarm gives a remote signal when the breaker trips on fault, not just manual operation. Power dissipation at full 200 A load is 44.5 W — include that in your panel thermal budget to avoid hot spots.
Yes, it is equipped with an undervoltage release (UVR) as the auxiliary release, plus 2 auxiliary switches and 1 trip alarm switch.
