The ETU550M electronic trip unit gives you LSI protection: long-time (overload) adjustable from 160 A to 400 A, short-time (short-circuit) from 1.2x to 15x In, and instantaneous from 3x to 15x In. That range covers most medium motor loads — pumps, conveyors, compressors — where you need thermal memory and selective coordination downstream. ## What's on the nameplate Built into the 3VA2 IEC frame 630 platform with busbar connection.","metaTitle":"Siemens 3VA2440-5MP32-0AF0 Circuit Breaker, 55 kA @ 415 V, 4","metaDescription":"Siemens 3VA2440-5MP32-0AF0 IEC frame 630 motor protection circuit breaker, 55 kA breaking capacity @ 415 V, 400 A In, ETU550M LSI trip unit.
