It carries an ETU350 LSI trip unit, adjustable overload protection Ir from 160A to 400A, short-circuit protection Isd from 1.5 to 10 x Ir, and instantaneous Ii fixed at 10 x In. The ETU350 LSI trip unit gives you selective coordination: adjust the long-time (Ir) for cable protection, short-time (Isd) for downstream breaker selectivity, and instantaneous (Ii) for bolted faults. The 24V DC undervoltage release ensures the breaker trips on loss of control voltage, meeting safety disconnection requirements in emergency-stop circuits. The auxiliary and alarm switches feed status back to a PLC or indication lamp.","metaTitle":"Siemens 3VA2340-5HN32-0BF0 Circuit Breaker, 55kA @ 415V, 400","metaDescription":"Siemens 3VA2340-5HN32-0BF0 IEC frame 400 MCCB, 55kA breaking capacity at 415V, ETU350 LSI trip, 400A In.
