The 3VA1180-3EF32-0HH0: The 80 A rating holds flat through 50 °C ambient; above that it derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. Physical footprint is 130 mm high, 76.2 mm wide, 70 mm deep — fits standard panel-mount cutouts for 3-pole MCCBs in the 80 A class. Front protection is IP40, suitable for enclosed distribution boards.
The shunt trip order code is 3VA9688-0BL30.
Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. These values determine the maximum fault current the breaker can safely interrupt at each voltage level.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.
It uses a TM240 thermal-magnetic overcurrent release. This is a fixed-trip unit — no interchangeable trip blocks — designed for line protection in distribution applications.
