IP40 on the front means it keeps out tools and fingers in a closed panel; the body itself isn't rated for washdown, so mount it inside a suitable enclosure. ## What you need for panel fit Dimensions: 130 mm tall, 76.2 mm wide, 70 mm deep—standard 3-pole MCCB footprint for DIN-rail or screw-mount panels. Rated insulation voltage 800 V, max operational voltage 500 V DC. Power loss max 12 W—factor that into your thermal budget if you're stacking breakers in a sealed enclosure. ## Temperature derating — stays flat to 55 °C Rated 20 A from 40 °C through 55 °C ambient, then 19 A at 60–70 °C—useful headroom for hot panels or outdoor cabinets.","metaTitle":"Siemens 3VA1120-6EE36-0AA0 SENTRON MCCB, 20A, 3-Pole, 220kA","metaDescription":"Siemens SENTRON 3VA1120-6EE36-0AA0 molded case circuit breaker. 20A rated, 3-pole, TM220 release.
