Interrupting capacity reaches 187 kA at 240 VAC, 121 kA at 415 VAC, and 75.6 kA at 440 VAC, with a floor of 17 kA at 500 V and 690 VAC — sufficient for high-fault panelboards and main distribution switchboards where SCCR headroom is critical. ## Mounting and Integration — DIN-Rail Panel Fit The breaker occupies a 76.2 mm wide, 130 mm tall, 70 mm deep footprint — three standard 25 mm DIN-rail module widths — and mounts directly onto a DIN rail in the distribution panel. Front face carries an IP40 protection rating, meaning tools and fingers are kept out, but the enclosure is not sealed against moisture — suitable for indoor panel installation only.","metaTitle":"Siemens 3VA1140-5EE36-0AA0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1140-5EE36-0AA0 molded case circuit breaker, 40 A, 3-pole, TM220 trip unit.
