The Siemens 3VA1180-5GD42-0AA0 is a SENTRON molded case circuit breaker (MCCB) in the 3VA platform, configured as a 4-pole line protection device with an 80 A rated continuous current (Iu) and a TM210 thermal-magnetic release.
This breaker delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. At 415 V, the 121 kA rating covers most industrial distribution boards fed by a transformer of several MVA; at 690 V the 17 kA figure still handles typical motor-control-centre fault levels.
Thermal derating — don't lose capacity in a hot panel
The 80 A rating holds flat from 40 °C through 50 °C, then derates gradually: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.
Physical fit and optional motor drive
Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — a standard 4-pole MCCB footprint for DIN-rail or screw-mount panel integration. The 100% N-conductor protection design means the neutral pole is fully rated, not reduced. The product extension for a motor drive is available as an optional accessory, enabling remote electrical tripping or closing without manual actuation.
