The Siemens 3VM1180-3GD42-0AA0 is a SENTRON molded case circuit breaker (MCCB) with a TM210 thermal-magnetic release, rated 80 A continuous current at 40 °C through 50 °C. It carries 76 kA interrupting capacity at 240 V AC, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V — the voltage-dependent curve that tells you exactly where this breaker can safely clear a fault without upstream coordination failure. The 4-pole design (3 phases + neutral) and 690 V AC rated operational voltage cover most industrial low-voltage distribution panels.
Thermal derating and continuous current
The 3VM1180-3GD42-0AA0 holds 80 A from 40 °C to 50 °C ambient, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. The TM210 release is thermal-magnetic, so no electronic adjustment; trip curve is fixed.
Dimensions: 70 mm depth, 101.6 mm width, 130 mm height.
