The ETU350 electronic trip unit gives you adjustable long-time delay (tr) from 0.5 to 17 seconds, short-time delay (tsd) from 0.04 to 0.4 seconds, and adjustable Ir up to 800 A with instantaneous pickup (Ii) up to 8000 A. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — enough for high-fault utility feeds or transformer secondaries. This is the line protection version (not feeder or motor protection), so it's optimized for cable and busbar protection in main distribution boards. The ETU350's adjustable time-current curves let you coordinate selectively with downstream breakers — critical for keeping a fault on one branch from dropping the whole plant. Dimensions are 120 mm deep, 210 mm wide, 320 mm high. The 210 mm width (8.3 in) is the standard 3-pole MCCB footprint for this current class — it fits the same cutout and busbar spacing as other SENTRON 3VA2 frame breakers. ## What the ETU350 trip unit lets you set The electronic overcurrent release (ETU350) is field-adjustable: Ir from 0.4× to 1.0× Iu (320–800 A), long-time delay tr from 0.5 to 17 seconds, short-time pickup Isd from 1.5× to 10× Ir with delay tsd from 0.04 to 0.4 seconds (I²t on/off), and instantaneous Ii from 1.5× to 10× Ir (max 8000 A). Ground fault protection is not included on this variant — the listing confirms 'without' ground fault monitoring.","metaTitle":"Siemens 3VA2580-5HN32-0AB0 SENTRON MCCB, 800 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2580-5HN32-0AB0 SENTRON molded case circuit breaker, 800 A rated current, 3-pole, ETU350 electronic trip, breaking capacity 187 kA at 240 V.
