That 17 kA floor at 690 V is still respectable for most industrial distribution, but if your fault current at 690 V exceeds that, you need a different frame. ## Built-in undervoltage release and auxiliary switches Also included: two HQ auxiliary switches for remote status indication (open/closed/tripped). No communication function or ground-fault monitoring on this version — it's a straight line-protection breaker. ## Thermal derating and power loss Rated current holds flat at 80 A from 40 °C up to 50 °C, then steps down: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C. Maximum power loss at rated load is 21.7 W — that's the heat the panel must vent.","metaTitle":"Siemens 3VA1180-5EF36-0DC0 SENTRON MCCB, 80 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1180-5EF36-0DC0 SENTRON molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 187 kA breaking at 240 V.
