It carries an In=400 A continuous rating and uses the ETU550M electronic trip unit with LSI protection — long-time (overload) adjustable Ir=160…400 A, short-time Isd=1.2…15×In, and instantaneous Ii=3…15×In. Busbar connection is standard. The ETU550M LSI trip unit gives you adjustable overload (Ir), short-time (Isd), and instantaneous (Ii) settings, so you can coordinate with downstream motor starters and upstream feeders. The 400 A frame and adjustable Ir down to 160 A mean it covers a wide motor FLA range, but the minimum Ir of 160 A sets the floor for the motor you protect. This MCCB is designed for motor branch circuits in industrial control panels — typically feeding a motor starter or soft starter for pumps, fans, conveyors, or compressors. The LSI trip characteristic allows selectivity with downstream overload relays and short-circuit protection devices. The busbar connection suits it for main or sub-feed distribution in switchboards and motor control centers (MCCs).","metaTitle":"Siemens 3VA2440-5MP32-0KD0 Circuit Breaker, 55kA @ 415V, 400","metaDescription":"Siemens 3VA2440-5MP32-0KD0 IEC frame 630 MCCB, 55kA breaking capacity at 415V, 400A motor protection with ETU550M LSI trip.
