The ETU550 electronic trip unit provides LSI protection (long-time, short-time, instantaneous) with adjustable Ir from 160 A to 400 A, Isd from 0.6 to 10x In, and Ii from 1.5 to 10x In, giving you granular selectivity coordination downstream. The built-in shunt trip on the left side operates on 208–277 V AC 50/60 Hz or 220–250 V DC, allowing remote emergency-off or undervoltage release without an external relay. The neutral conductor protection is adjustable from OFF to 100% of In, covering both grounded and ungrounded distribution schemes. ## Deployment context","metaTitle":"Siemens 3VA2340-6JP42-0KE0 Circuit Breaker, 400A, 85kA @ 415","metaDescription":"Siemens 3VA2340-6JP42-0KE0 IEC frame 400 breaker, 85kA breaking capacity at 415V, ETU550 LSI protection, 400A rated current.
