The Siemens SENTRON 3VA1080-3ED42-0HH0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 80 A at 40 °C through 50 °C, and derating to 72 A at 70 °C.
At 240 V this breaker interrupts 75.6 kA, at 415 V it handles 52.5 kA, at 440 V it drops to 32 kA, and at 690 V it's 7.5 kA.
The 3VA1080-3ED42-0HH0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — it fits standard panel-mount cutouts for 4-pole MCCBs in the 80 A frame. The shunt trip (STL) and auxiliary contacts are wired via the integrated terminal block; the trip alarm switch (HQ) gives a separate signal for remote annunciation.
