Interrupting Capacity and Thermal Derating
This MCCB delivers 52.5 kA interrupting capacity at 240 V, dropping to 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — so the available fault current at your panel's line voltage determines whether this breaker has enough headroom. The 80 A rating holds steady up to 50 °C; above that it derates to 76.8 A at 55 °C and 72 A at 70 °C.
The 3VA1080-2ED42-0BH0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — a standard MCCB footprint for panel-mounting on a DIN rail or direct screw-fix.
