The ETU340 electronic trip unit gives you adjustable N-conductor protection (OFF, 50%, or 100%) and a fixed long-time delay of 1500 ms, so coordination studies can rely on a known trip curve without field tweaks. Breaking capacity hits 440 kA at 240 V and still holds 53 kA at 690 V, meaning this breaker clears high-fault scenarios on the line side without cascading upstream. The breaker measures 140 mm wide by 181 mm tall by 86 mm deep, so it fits standard SENTRON 3VA panel cutouts and busbar systems. Four-pole construction means it occupies the same footprint as a 3-pole plus a neutral pole in a single molded case — no add-on neutral module required. ## Selectivity and coordination — where the 440 kA matters With 440 kA interrupting capacity at 240 V and 330 kA at 415 V, this MCCB can sit directly downstream of a main breaker or transformer without needing a current-limiting fuse upstream for fault clearance. The ETU340's fixed 1500 ms long-time delay gives predictable coordination with downstream 3VA feeders or branch breakers — useful when a site electrical engineer is building a selective coordination study per NEC 240.86 or IEC 60947-2.","metaTitle":"Siemens 3VA2110-8HK42-0AA0 SENTRON MCCB, 100 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2110-8HK42-0AA0 SENTRON molded case circuit breaker, 100 A rated continuous current at 70 °C, 4-pole, ETU340 release, 440 kA at 240 V.
