SENTRON 3VA1180-5EF32-0AE0 — 80 A MCCB with TM240 Release
Breaking capacity reaches 187 kA at 240 V, dropping to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V, so the part is sized for high-fault industrial distribution where the upstream transformer can deliver those prospective currents.
Thermal Derating and Ambient Constraints
Above that, the TM240 release begins to pull back: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.
Auxiliary Switching and Panel Integration
This variant ships with four auxiliary switches (HQ type) built in — no separate add-on module needed. That covers status feedback for a PLC or remote indication on all three poles plus a spare. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — standard 3-pole MCCB footprint for DIN-rail or mounting-plate installation.
