That flat thermal curve is unusual; most breakers start stepping down current above 40 °C, so this one buys headroom in a tightly packed switchboard. The ETU340 electronic trip unit handles the overcurrent protection logic. It is a solid-state release with adjustable N-conductor protection — set it to OFF, 50 %, or 100 % of the phase current depending on whether the neutral carries load or just fault current. That adjustability matters when the same breaker frame serves both distribution and feeder duty in a single panel build. Interrupting capacity is the headline number here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. The breaker measures 110 mm deep, 184 mm wide, and 248 mm tall. Depth is the critical dimension for enclosure selection. Front protection is IP40 — splash-proof from the front but not sealed. It is a straight electromechanical line-protection device; any remote tripping or monitoring requires an external shunt trip or auxiliary switch added to the accessory slots. Maximum power loss is 37.5 W. In a multi-breaker lineup that heat adds up — account for it in the enclosure ventilation calculation, especially if the panel is sealed to IP54 or higher.","metaTitle":"Siemens 3VA2325-7HK42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2325-7HK42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, ETU340 electronic trip unit.
