Its interrupting capacity reaches 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — meaning it can safely clear faults up to those levels without upstream cascading, a critical spec for high-fault installations like transformer secondaries or large motor control centers.
The 86 mm depth, 105 mm width, and 181 mm height fit standard MCCB mounting footprints; the 3-pole block occupies roughly the same DIN-rail or backplate space as other SENTRON 3VA frames.
No undervoltage release is fitted, and no ground-fault monitoring module is included — those are separate add-on options. The basic switch assembly is order code 3VA2225-8HL32-0AA0. A voltage trigger and trip indicator are present on the front face for local status indication.
Environmental and Power Loss
No communication function or other measurement function is built in; this is a straight line-protection breaker.
