Breaking capacity is the real story here: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. This is a straightforward feeder or main breaker for a distribution panel. Keep it inside the panel, not on the door. ## Power loss and thermal considerations Maximum power loss is 13.5 W. In a densely packed panel, that heat adds up — account for it in the enclosure's thermal budget.","metaTitle":"Siemens 3VA2010-5HL42-0AA0 SENTRON MCCB, 100A, 4-Pole, ETU32","metaDescription":"Siemens SENTRON 3VA2010-5HL42-0AA0 molded case circuit breaker, 100A continuous at 70°C, 187kA at 240V AC, 4-pole, ETU320 trip unit.
