That 80 A holds flat through 50 °C — no derating needed in a typical 40 °C panel — then steps down to 76.8 A at 55 °C and 72 A at 70 °C, per the datasheet. For a line protection role on a 3-pole circuit, the interrupting capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. The 52.5 kA at 240 V covers high-fault commercial services; the 32 kA at 415 V handles most industrial distribution. The 690 V rating (7.5 kA) is lower but still adequate for many 690 V motor circuits. That simplifies ordering but locks the breaker to its 80 A frame. A shunt trip (STL) is integrated; no undervoltage release is fitted. No communication function, no phase failure detection, no ground fault monitoring — this is a basic, reliable line-protection MCCB for standard distribution panels.
The 3VA1080-2ED36-0KH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep.
