Motor protection MCCB with ETU550M — 160 A, 110 kA @ 415 V
The Siemens 3VA2216-7MP32-0AA0 is a 3-pole molded case circuit breaker in the 3VA2 IEC frame 250 series, rated 160 A continuous with a breaking capacity of 110 kA at 415 V (class C). It carries the ETU550M electronic trip unit configured for LSI protection — long-time (Ir = 63…160 A), short-time (Isd = 1.2…15× In), and instantaneous (Ii = 3…15× In) — purpose-built for motor branch-circuit protection where adjustable overload and short-circuit coordination are required. The 110 kA Icu at 415 V means this breaker can safely interrupt fault currents up to that level without upstream fuses or a current-limiting reactor, provided the panel SCCR is coordinated to that value. For IEC installations, the class C designation typically aligns with standard industrial distribution — not the extreme high-fault ratings of class A or the economy class D.
Supply posture — quoted to order against RFQ
As a class C made-to-order part, 3VA2216-7MP32-0AA0 is sourced through the Siemens authorized channel on a per-order basis. Availability and current pricing are confirmed at quote time against an RFQ. The nut keeper kit is included in the order code — verify that the panel mounting hardware matches the frame 250 footprint before specifying.
