SENTRON 3VA2010-6JQ46-0AA0 — 100 A, 4-Pole MCCB with Communication
At 415 V and 440 V it still holds 187 kA, dropping to 121 kA at 500 V and 3 kA at 690 V, so the SCCR headroom is there for most industrial low-voltage networks. This breaker carries a communication function onboard, which means it can report status and trip events to a building management or SCADA system without an add-on module — useful for remote monitoring on a critical feeder. The ground-fault monitoring uses summation current formation on L+N conductors, so it detects leakage without a separate GFCI module.
Integration and Panel Fit
The communication function integrates with Siemens SENTRON powerconfig software or higher-level BMS via the built-in interface — no separate communication module to buy and slot. For a retrofit into an existing panel that was specified around a different 4-pole MCCB, verify the busbar pitch and mounting hole pattern against the 140 mm width; the depth at 86 mm leaves clearance for most standard enclosure depths.
