The Siemens 3VA2010-5KP36-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current, configured as a 3-pole unit with an ETU850 electronic trip unit. It is designed for line protection in distribution panels and motor control centers where adjustable protection curves and communication capability are needed. The interrupting ratings are substantial: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — meaning this breaker can handle high-fault locations without cascading upstream.
Ratings and what they mean for fit
The 100 A continuous rating holds flat from 40 °C through 70 °C ambient — no derating needed in a warm enclosure. That is a practical advantage for panels mounted near process heat or in non-conditioned electrical rooms. The ETU850 electronic trip unit provides adjustable overload and short-circuit protection, with communication capability for remote monitoring and coordination studies. Physical footprint: 105 mm wide, 181 mm high, 86 mm deep. The 3-pole body fits standard MCCB mounting patterns in SENTRON and third-party distribution panels. Front IP40 protection keeps tools and accidental contact out of the mechanism. Insulation voltage rated at 800 V, so the breaker is suitable for 690 V line-to-line systems common in European and IEC installations. The storage temperature range of -40 °C to 80 °C covers most warehouse and shipping conditions without concern.
Deployment context
This MCCB mounts in a distribution panel or MCC bucket on a standard DIN rail or bolted bus connection. The 100 A rating and high interrupting capacity make it a fit for main or feeder protection in industrial plants, commercial buildings, and infrastructure where fault currents exceed 100 kA at lower voltages. The communication function supports integration with energy management systems for load monitoring and remote tripping.
