SENTRON 3VA2110-7MN36-0JH0 — 100 A MCCB for Motor Protection
The Siemens SENTRON 3VA2110-7MN36-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated at 100 A continuous current from 40 °C up to 70 °C — no derating needed across that span, which simplifies panel thermal budgeting. It's designed specifically for motor protection, with integrated phase failure detection and a shunt trip release (STL) for remote tripping. The auxiliary switch block carries 2 auxiliary switches plus 1 trip alarm switch HQ, giving the control system full status feedback without an add-on module.
Breaking Capacity — What the Ratings Mean
Breaking capacity is the fault current this MCCB can safely interrupt without welding contacts or venting gas. At 240 V it handles 330 kA — that's a very high rating, typical for a heavy-duty SENTRON frame used in large distribution or motor control centers fed by high-capacity transformers. At 415 V and 440 V it's still 242 kA, enough for most industrial low-voltage networks. At 690 V the capacity drops to 3.7 kA, so for 690 V applications this breaker is limited to low-fault-current branch circuits.
Panel Fit and Integration
Mounts on a DIN rail or panel-mount base — the SENTRON 3VA family uses a common footprint. Depth is 86 mm, width 105 mm, height 181 mm. The shunt trip release (STL) and auxiliary switches are factory-fitted, so no field wiring of separate accessories is needed. The 3VA2110-7MN36-0JH0 ships with the basic switch assembly 3VA21107MN360AA0 inside the molded case.
