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.
Ratings and what they mean for fit
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. The undervoltage release (UVR) trips the breaker when supply voltage drops, which is useful for preventing motor restart after a brownout.
Integration and panel fit
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.
