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 breaker itself carries no undervoltage release and no ground-fault monitoring, so those functions would need external modules if required.
