The continuous current rating In is 400 A, with overload protection (Ir) adjustable from 160 A to 400 A and short-circuit protection (Isd) from 1.5 to 10 times Ir. Instantaneous pickup (Ii) is fixed at 10 times In. The unit ships with a shunt trip accessory wired on the left side, rated 208–277 V AC 50/60 Hz and 220–250 V DC, plus one auxiliary contact. For current pricing and availability, submit an RFQ against this order code. The ETU350 LSI trip unit allows field-adjustable long-time, short-time, and instantaneous pickup settings, giving the commissioning engineer selectivity coordination flexibility downstream of a larger feeder breaker. The shunt trip accessory on the left side accepts either AC (208–277 V) or DC (220–250 V) control voltage, so it can be wired into an emergency-stop circuit or remote-trip system without an intermediate relay. The auxiliary contact provides a status signal for the PLC or SCADA input.","metaTitle":"Siemens 3VA2340-5HN32-0KK0 Circuit Breaker, 400A, 55kA @ 415","metaDescription":"Siemens 3VA2340-5HN32-0KK0 IEC frame 400 MCCB, 3-pole, 55kA Icu @ 415V AC, ETU350 LSI trip, 400A In, shunt trip left.
