Rated continuous current Iu is 80 A, which holds steady up to 50 °C ambient; above that it derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C, so the 80 A rating stays usable in most standard panel ambient conditions without a frame-size bump. This MCCB carries breaking capacities of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. The 690 V rating of 10.5 kA covers the less common 600 V class installations. A trip indicator is present on the front for local visual confirmation. The integrated auxiliary trip order code for the release is 3VA9608-0BB25, useful if you need a spare or replacement. No communication function, phase failure detection, or ground fault monitoring is built in — this is a plain line-protection MCCB, not a metering or communicating device. ## Mounting and environment The 3VA1180-3EF36-0DH0 measures 70 mm deep, 76.2 mm wide, and 130 mm high — a compact 3-pole footprint that fits standard SENTRON panel-mounting cutouts. Protection class on the front is IP40, so it is protected against tools and small solid objects but not sealed against moisture; install in a clean, dry enclosure.","metaTitle":"Siemens 3VA1180-3EF36-0DH0 SENTRON MCCB, 80 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1180-3EF36-0DH0 molded case circuit breaker, 80 A, 3-pole, line protection.
