It sits in the 3VA2 platform, which is the current-production SENTRON family — no lifecycle concern for a new BOM line. Breaking capacity is the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. The 110 mm depth means it clears shallow enclosures where a deeper frame would hit the gland plate.
At 55 °C it derates to 384 A, at 60 °C to 376 A, at 65 °C to 368 A, and at 70 °C to 360 A.
The UVR is factory-fitted — no field retrofit needed if the spec calls for undervoltage protection. The auxiliary switches provide status feedback for PLC or indication circuits. No voltage trigger, no communication function, no phase failure detection, and no ground fault monitoring on this variant. It is a straight line-protection breaker with the ETU350 — adjustable long-time, short-time, instantaneous, and ground-fault (though the ground-fault element is not wired on this version).
