The Siemens SENTRON 3VA1140-3EF36-0HH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 40 A across the 40 °C to 50 °C band and derating to 37 A at 70 °C. Its interrupting capacity hits 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 11.9 kA at 690 V — figures that govern selectivity coordination in a distribution panel.
The 32 kA at 440 V and 11.9 kA at 690 V track the expected voltage-derate curve; selectivity tables from the SENTRON manual should be consulted for coordination with upstream 3VA breakers or SIRIUS fuses.
The auxiliary contacts report breaker position to the control system.
Rated 40 A from 40 °C through 50 °C ambient; drops to 39 A at 55–60 °C and 38 A at 65 °C, then 37 A at 70 °C (–). Maximum power loss is 10.8 W — relevant for enclosure heat rise calculations when grouping multiple breakers.
This is an active Siemens SENTRON 3VA catalog line — no phase-out notice on record.
