Breaking capacity is 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 500 V — numbers that put it in the high-interrupting range for a 100 A frame.
The trip indicator is present, so you get a visual flag on the breaker face after a fault trip — useful for line-down diagnostics without opening the panel door. Maximum power loss is 12.5 W.
Yes, it ships with an undervoltage release (UVR) and a 2 auxiliary + 1 trip alarm switch configuration.
