The ETU350 electronic trip unit handles the overcurrent protection curve; an undervoltage release (UVR) is factory-fitted. Breaking capacity hits 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — so the 240 V figure is the headline, but the 415 V/440 V rating is what drives most industrial panel coordination studies. Footprint is 138 mm wide by 248 mm tall by 110 mm deep — standard 3-pole MCCB form factor for a 400 A frame. The 138 mm width occupies three 45 mm module spaces — verify gland plate cutouts if retrofitting into an existing MCC bucket. The undervoltage release (UVR) is wired separately; confirm control voltage matches the panel's 24 VDC or 110/230 VAC supply before commissioning. The ETU350 trip unit is field-replaceable without removing the breaker from the panel.","metaTitle":"SENTRON 3VA2340-5HN32-0BH0 MCCB, 400 A, 187 kA at 240 V","metaDescription":"SENTRON 3VA2340-5HN32-0BH0 molded case circuit breaker, 400 A rated, 187 kA breaking at 240 V.
