The ETU330 electronic trip unit handles the overcurrent protection logic. It is a line-protection variant, meaning it is configured for feeder and distribution duty rather than motor or generator protection — the trip curves and time-delay settings are tailored for cable and busbar protection in a main or sub-distribution panel. Breaking capacity is substantial: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. The undervoltage release is present, so the breaker can be shunt-tripped via a separate control voltage for emergency-stop or undervoltage protection schemes.","metaTitle":"Siemens 3VA2225-5HM42-0DF0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2225-5HM42-0DF0 SENTRON molded case circuit breaker, 250 A rated, 4-pole, ETU330 electronic trip unit, 187 kA at 240 V.
