The Siemens 3VA1010-3ED42-0DH0 is a SENTRON molded case circuit breaker (MCCB) rated 100 A at 40 °C, with a 4-pole configuration and a maximum interrupting capacity of 75.6 kA at 240 V.
Interrupting Ratings and Thermal Derating
Interrupting capacity varies with voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500 V and 690 V. This means the breaker can safely clear faults up to those levels depending on the system voltage — critical for selectivity studies on a 480 V or 400 V line. Thermal rating holds at 100 A from 40 °C through 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.
Physical Fit and Auxiliary Configuration
Dimensions: 70 mm depth, 101.6 mm width, 130 mm height. The 4-pole footprint fits standard panel-mount cutouts for SENTRON 3VA frames.
