The Siemens SENTRON 3VA2010-5HN32-0AJ0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with an electronic ETU350 trip unit. Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 3.4 kA at 690 V — meaning it can clear high-fault currents at common distribution voltages without upstream coordination headaches.
The breaker carries its full 100 A rating from 40 °C up to 50 °C, then derates linearly to 85 A at 70 °C.
It is rated 121 kA at 415 V, matching the 440 V figure; at 500 V it drops to 79 kA, and at 690 V to 3.4 kA.
This part is sourced to order against an RFQ through independent distribution channels; availability and current pricing are confirmed at quote time.
As a Siemens SENTRON MCCB, it is designed to meet IEC 60947-2 and UL 489 standards; specific RoHS and REACH declarations are available from the manufacturer upon request.
