Its interrupting capacity hits 220 kA at 240 V, dropping to 154 kA at 415 V and 121 kA at 440 V — numbers that give real selectivity headroom in a high-fault panel. The 70 mm depth (2.76 in) and 76.2 mm width (3 in) slot into standard SENTRON mounting footprints, so swapping in a panel that already holds 3VA breakers is a straight drop.
At 55 °C it drops to 98 A, and at 70 °C it's still at 91 A, which is better than many MCCBs that shed 20 % by that point.
The UVR means the breaker drops out if control voltage falls below a threshold — standard for emergency-stop circuits and safety isolation where you want the breaker to open on loss of control power. The trip indicator (a red flag on the front) tells a technician at a glance whether it tripped on fault or was manually opened, which saves troubleshooting time on a line-down call.
