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. This 3-pole breaker is designed for line protection and includes an integrated undervoltage release (UVR) and communication function, making it a fit for main feeders or large subfeeders in industrial switchboards where remote monitoring or undervoltage tripping is required.
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. These high fault-current ratings give the 3VA2010-5KP32-0CH0 headroom for most industrial service-entrance or distribution applications, particularly where the available fault current is above 100 kA. 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.
Physical Fit and Panel Integration
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep. 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.
Auxiliary and Release Configuration
This variant ships with 2 auxiliary switches plus 1 trip alarm switch (HQ configuration) and an undervoltage release (UVR). The UVR trips the breaker when control voltage drops below a threshold.
