The Siemens SENTRON 3VA1096-3ED42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated 16 A continuous at 40 °C, carrying a TM210 thermal-magnetic release for line-protection duty in distribution panels and sub-feeders.
Breaking capacity across voltages — selectivity planning
The interrupting rating drops as line voltage climbs: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 7.5 kA floor at 690 V is the number to coordinate against when this breaker feeds a 690 V step-down transformer or a VFD input section — upstream protection must clear faults the MCCB cannot.
Thermal derating and power loss
Rated 16 A from 40 °C through 55 °C, then derates to 15 A at 60–70 °C. The 10.6 W maximum power loss matters for panel heat budgeting — in a sealed enclosure with multiple breakers, that figure goes into the thermal rise calculation.
Panel fit — dimensions and mounting
Width is 101.6 mm (4 in), depth 70 mm (2.76 in), height 130 mm (5.12 in).
