Siemens 3VA2110-5HL32-0JA0 — 100 A SENTRON MCCB with Shunt Trip
The Siemens 3VA2110-5HL32-0JA0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous current at 40 °C through 70 °C ambient — no derating needed across that span, which simplifies panel thermal budgeting. It is designed for line protection (cable/feeder) rather than motor or generator duty, so the trip curve and accessories are optimized for overcurrent and short-circuit isolation on distribution circuits. Breaking capacity runs from 187 kA at 240 V down to 3.7 kA at 690 V, with 121 kA at 415 V and 440 V — numbers that place it solidly in the high-interrupting class for industrial switchboards. The 800 V rated insulation voltage means it can be applied on 690 V systems without series-derating the insulation coordination. A shunt trip release (STL) is factory-fitted, allowing remote tripping via a control signal — useful for emergency-stop circuits or interlocking with upstream protection. The breaker itself carries no undervoltage release and no ground-fault monitoring, so those functions would need external modules if required.
Panel Fit and Dimensions
The breaker measures 105 mm wide by 181 mm high by 86 mm deep — a standard SENTRON 3VA2 footprint that fits existing Siemens switchboard cutouts and busbar systems. The 86 mm depth is shallow enough for most 400 mm deep enclosures without crowding the gland plate.
