Siemens 3VA2216-5MP32-0AA0 is a SENTRON molded case circuit breaker for motor protection — 160 A continuous, 3-pole, with an ETU550M electronic trip unit supporting adjustable trip classes 10A, 10/10E, 20/20E, and 30.
Rated breaking capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V.
Motor protection trip unit
The ETU550M is a microprocessor-based overcurrent release with phase failure detection and communication capability. Adjustable trip class lets you match the thermal curve to motor start profiles — class 10A for fast starts (short stall time), class 30 for high-inertia loads like centrifuges or crushers.
