Siemens 3VA2010-5KP32-0CH0 SENTRON MCCB — 100 A, 3-Pole, Line Protection with Undervoltage Release
The Siemens 3VA2010-5KP32-0CH0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current across an ambient range of -25 °C to 70 °C, with no derating needed up to 70 °C.
Interrupting Capacity and Selectivity Planning
The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. The 3 kA at 690 V limits its use on 690 V systems to lower-fault locations or as a downstream breaker with current-limiting upstream protection.
The 105 mm width is standard for a 3-pole SENTRON 3VA frame, fitting the same mounting footprint as other 3VA breakers in the 100 A class. The depth of 86 mm leaves room for rear-access wiring or busbar connections in a typical switchboard enclosure.
