The Siemens 3VA2010-5HL32-0CC0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C, with an ETU320 electronic trip unit for line protection.
At 415 V and 440 V it holds 121 kA; at 500 V it still delivers 79 kA.
Rated current holds flat at 100 A from 40 °C to 50 °C, then derates linearly to 85 A at 70 °C. In a tightly packed panel with ambient near 60 °C, you lose about 7.5 A — plan your load accordingly.
Integrated auxiliary and undervoltage release
This variant ships with two HQ auxiliary switches (form C) and an undervoltage release (UVR) factory-fitted.
