What this MCCB does for a motor circuit
The Siemens SENTRON 3VA2216-0MQ32-0AA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current with an interrupting capacity of 440 kA at 415 V. It is designed specifically for motor protection, meaning its trip curve and release logic are tuned to handle the inrush and overload profile of a motor load — not just a distribution feeder. The ETU860M electronic overcurrent release gives you adjustable trip classes: 10A, 10/10E, 20/20E, and 30, so you can match the thermal memory to the motor's starting time and avoid nuisance trips on a cold start.
The depth of 86 mm leaves clearance for rear-mounted busbars or a backplate in a typical 600 mm deep enclosure.
Communication and monitoring functions
The ETU860M release includes a communication function, phase failure detection, and other measurement functions. That means you can pull real-time load data and fault events into a control system — useful for predictive maintenance and reducing unplanned downtime on a continuous process line.
