Siemens 3VA1080-2ED36-0KC0 — 80 A SENTRON MCCB, Line Protection, TM210 Release
The Siemens 3VA1080-2ED36-0KC0 is a SENTRON molded case circuit breaker (MCCB) rated for 80 A continuous current at 40 °C, with a 3-pole configuration and a TM210 thermal-magnetic overcurrent release. It is designated for line protection per DIN EN 81346-2 reference code Q. Breaking capacity reaches 52.5 kA at 240 V and 32 kA at 415 V, dropping to 13.6 kA at 440 V and 7.5 kA at 690 V.
Thermal Derating and Ambient Performance
Above that, derating begins: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. If the panel interior runs hot — common in sealed enclosures or high-density MCC rows — the 80 A frame may need to be applied at a lower continuous load to stay within the thermal curve. The storage limits govern handling and warehousing, not running conditions.
Physical Fit and Auxiliary Options
Comes with 2 auxiliary switches (HQ version) pre-installed. The integrated shunt trip (STL) is specified as order code 3VA9688-0BL33 — verify compatibility if replacing an existing trip unit. No trip indicator is fitted on this variant. Latching endurance: 15,000 operations.
