Above that, it derates gradually: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. The 3-pole footprint is standard for 80 A MCCBs, so it swaps into existing cutouts sized for comparable SENTRON or third-party breakers without panel rework. ## What's not included — and why that matters for your BOM This variant ships without an undervoltage release, without ground-fault monitoring, without phase-failure detection, and without a voltage-trip or communication module. It's a straight thermal-magnetic breaker with four auxiliary switches. If your design requires shunt trip, UVR, or remote monitoring, you'll need a different order code from the 3VA family or add external relays. The TM240 release's adjustable magnetic threshold (tr max 1 s) covers short-circuit protection for most feeder and branch circuits up to 240 A magnetic pickup.","metaTitle":"Siemens 3VA1180-5EF36-0AE0 SENTRON MCCB, 80 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1180-5EF36-0AE0 molded case circuit breaker, 80 A, 3-pole, TM240 release, 187 kA at 240 V.
