That 100 A holds steady at every 5 °C step, so the breaker's thermal behaviour is flat through the typical enclosure rise. The ETU330 electronic trip unit gives you adjustable N-conductor protection (OFF, 50%, or 100%) and an initial setting of 20 A, with a full-scale range up to 100 A. ## Footprint and panel integration ## Trip unit and protection features The ETU330 electronic overcurrent release provides adjustable N-conductor protection — set to OFF, 50%, or 100% of the phase current — which is useful for 4-wire systems where neutral overload protection is required. Ground-fault monitoring uses summation current formation on L + N conductors, so it can detect residual currents without an external module.","metaTitle":"Siemens 3VA2110-0HM42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 440","metaDescription":"Siemens SENTRON 3VA2110-0HM42-0AA0 molded case circuit breaker, 100 A continuous, 4-pole, ETU330 release, 440 kA at 415 V.
