The 70 mm depth and 76.2 mm width keep it within the standard SENTRON 3VA footprint, so it bolts into existing 3VA busbar and mounting kits without re-drilling the panel. ## Thermal derating — what the 80 A rating actually means at elevated ambient Above 50 °C the TM240 release begins to derate: 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 your panel ambient sits at 55 °C — common in a cement plant control room or a hot MCC lineup — you design for 76.8 A continuous, not the label 80 A. That temperature span covers outdoor enclosures in a northern winter or a roof-mounted panel in summer. ## What you don't get — and why it matters for the spec No trip indicator, no auxiliary contacts, no communication function, no phase-failure detection, no ground-fault monitoring. This is a bare line-protection MCCB with an undervoltage release and a TM240 thermal-magnetic trip. If your panel requires remote status feedback or ground-fault alarm, you add an external auxiliary switch or a separate ground-fault relay. The IP40 front protection means it's sealed against tools and fingers on the front face, but the rear terminals are open to the panel — standard for switchboard mounting.","metaTitle":"Siemens 3VA1180-5EF36-0BA0 SENTRON MCCB, 80 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1180-5EF36-0BA0 SENTRON molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 187 kA at 240 V.
