SENTRON 3VA2010-6JQ46-0AA0 — 100 A, 4-Pole MCCB with Communication
The Siemens SENTRON 3VA2010-6JQ46-0AA0 is a 4-pole molded case circuit breaker rated for 100 A continuous current, designed for line protection in distribution panels. Its 242 kA breaking capacity at 240 V means it can safely interrupt very high fault currents typical at the service entrance or main feeder — the kind of fault that would weld a lower-rated breaker closed. 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. Physically, it measures 86 mm deep by 140 mm wide by 181 mm tall — a standard footprint for a 4-pole MCCB in this class, so it drops into existing SENTRON panel mountings without re-drilling. The continuous current holds flat at 100 A from 40 °C through 70 °C ambient, meaning no derating curve to calculate for warm enclosures.
Lifecycle and Sourcing
Sourcing is straightforward: quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — think landed, not list, especially if this breaker is headed across a border where duty and compliance documentation (RoHS, REACH, UL, IEC) need to be clean for customs.
Integration and Panel Fit
Mounts on a standard DIN rail or directly to a mounting plate via the SENTRON busbar system. The 4-pole construction handles three-phase plus neutral switching, which is typical for main breakers in North American and European distribution panels where the neutral must be switched or isolated. 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.
