The ETU330 electronic trip unit handles the overcurrent release, configurable for N-conductor protection at OFF, 50%, or 100%. Dimensions are 181 mm high by 140 mm wide by 86 mm deep. Ground-fault monitoring uses summation current formation of L + N conductors. No undervoltage release, no voltage trigger, and no communication function are built in; this is a straight line-protection breaker with the ETU330 doing the intelligent tripping. For selectivity studies, the ETU330's electronic trip curve gives a wider adjustment range than a thermal-magnetic unit, making downstream coordination easier.","metaTitle":"Siemens 3VA2010-8HM42-0AA0 SENTRON 4-pole MCCB, 100 A, ETU33","metaDescription":"Siemens 3VA2010-8HM42-0AA0 SENTRON molded case circuit breaker, 4-pole, 100 A continuous, ETU330 electronic trip unit.

The difference is the trip unit: 3VA2010-8HM42-0AA0 uses an ETU330, while 3VA2110-8HN32-0AA0 carries a different release. If the panel's wiring and bus bars are sized for the lower amp rating of the 3VA2110 variant, dropping in a 100 A unit is straightforward — but verify the load-side conductor ampacity matches the 100 A rating before committing."},{"question":"What is 3VA2010-8HM42-0AA0's listed depth?","answer":"The listed depth is 86 mm (3.39 inches)."},{"question":"What compliance documentation does this brand provide for 3VA2010-8HM42-0AA0?","answer":"As a SENTRON series MCCB, the 3VA2010-8HM42-0AA0 is designed to meet IEC 60947-2 and carries the reference code Q per IEC 81346-2.
