The 138 mm width and 248 mm height fit the standard SENTRON 3VA mounting footprint, so it swaps into existing panel layouts without re-drilling gland plates. Depth is 110 mm — that's the dimension that matters when you're up against a shallow enclosure back wall.
Above that, derate in 25 A steps: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, 300 A at 70 °C. Interrupting ratings climb with voltage: 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. Maximum power loss is 96 W.
Communication and auxiliaries
This variant includes a communication function — that means it can talk to a higher-level control system for remote monitoring and trip data, not just local indication. The supplied basic switch order code is 3VA2340-5JP32-0AA0 — that's the core breaker without the communication module. If you're ordering spares or need to match an existing panel, that's the base unit this one builds on.
