MCCB for high-fault panels
The Siemens SENTRON 3VA1116-6FD46-0AA0 is a 4-pole molded case circuit breaker rated 80 A continuous, with a TM210 thermal-magnetic overcurrent release designed for line protection in distribution panels. Its interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V — figures that place it squarely in high-fault-current applications where standard MCBs would weld shut. At 690 V the rating drops to 17 kA, so verify the available fault current at your service voltage before specifying. The 80 A frame is thermally rated to carry 160 A at 40 °C ambient, with a slight derating curve to 150 A at 70 °C — useful headroom for lightly loaded feeders or high-ambient enclosures.
Panel fit and integration
Dimensions are 101.6 mm wide, 130 mm high, and 70 mm deep. Front face carries IP40 protection. Rated insulation voltage is 800 V, so the internal clearances support 690 V line-to-line systems without additional creepage concerns.
