Motor protection with phase-loss coverage
This breaker is built for motor protection, not just general distribution. That UVR will drop the breaker if line voltage sags below the dropout threshold, which keeps a motor from single-phasing and burning up on the route.
Auxiliary switch complement
Time-delay curve and power loss
Maximum power dissipation is 12.5 W — modest enough that you don't need forced cooling in a standard panel, but it's worth accounting for in a tightly packed row of breakers.
