The Siemens SENTRON 3VA1010-2ED36-0DH0 is a 3-pole molded case circuit breaker (MCCB) rated 100 A at 40 °C, designed for line protection in distribution panels. Its breaking capacity reaches 52.5 kA at 240 V, tapering to 7.5 kA at 690 V — figures that govern fault-clearing capability across common low-voltage systems.
The 100 A rating holds continuously at 40 °C ambient; derate to 91 A at 70 °C if the panel runs hot. The 52.5 kA at 240 V is the maximum fault current the breaker can safely interrupt — downstream equipment must be coordinated so the available fault current stays under this threshold.
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON mounting footprints. The 3-pole design with integral undervoltage release and auxiliary switch configuration (2 aux + 1 trip alarm HQ) means it can be wired directly into existing control circuits without external add-on modules.
