It carries a full interrupting capacity table: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — the drop above 500 V means you need to check SCCR coordination if your fault current is high on a 690 V bus. That UVR means the breaker trips on loss of control voltage — standard for emergency-stop circuits or undervoltage protection schemes where you want the load isolated when the control supply drops.
Dimensions: 248 mm height, 138 mm width, 110 mm depth.
