Its interrupting capacity reaches 187 kA at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — numbers that matter when coordinating with upstream gear for arc-flash compliance. This is a line-protection design (not feeder or motor-protection), so it's sized for branch-circuit overcurrent protection in distribution panels. The TM240 release gives a fixed thermal curve with magnetic pickup at 240 A — 3× the 80 A frame rating — which suits general distribution loads rather than high-inrush motor starts. The 80 A rating holds flat from 40 °C through 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. The 70 mm depth × 76.2 mm width × 130 mm height footprint fits standard Siemens 3VA panel-mounting patterns and accepts the same busbar kits as other 3VA1 frame sizes. ## Auxiliary contacts and trip indication The trip alarm signals on overcurrent or short-circuit trip — useful for remote fault annunciation in a PLC or SCADA system. The trip indicator flag on the front gives a visual at-a-glance confirmation that the breaker has tripped, not been manually switched off — saves a panel walk when troubleshooting.","metaTitle":"Siemens 3VA1180-5EF36-0AH0 SENTRON MCCB, 80 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1180-5EF36-0AH0 molded case circuit breaker, 80 A, 3-pole, TM240 release, 187 kA breaking at 240 V.

The difference is in the release: this unit carries a TM240 (80 A frame, 240 A magnetic pickup), while the 3VA1110-5EF32-0AM0 uses a different release curve.
