Product identity and key ratings
The Siemens 3VA2010-6JP42-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current at an insulation voltage of 800 V. It is a 4-pole unit designed for line protection, fitted with an ETU550 electronic overcurrent release. Breaking capacity is specified per voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. These figures define the fault-clearing capability at the respective system voltages — critical for selectivity coordination studies.
Thermal performance and installation
The breaker carries its full 100 A rating from 40 °C to 70 °C without derating. Dimensions are 86 mm depth, 140 mm width, and 181 mm height. The IP40 rating on the front face indicates protection against tools and small wires — suitable for enclosed distribution boards where the front is behind a door or cover.
