Its adjustable thermal-magnetic trip unit covers a 600 A to 3 000 A range, so you set the continuous current to match the motor full-load amps.
That flat curve simplifies panel thermal budgeting: the 200 A rating holds even in a warm enclosure. Maximum power loss is 46 W at rated load, which feeds into your enclosure heat-rise calculation.
Interrupting capacity by voltage level
The SCCR varies with system voltage: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 5.2 kA at 690 V. At the common 400/415 V distribution level, the 242 kA figure gives you headroom for high-fault panels without cascading upstream breakers. The 690 V rating drops to 5.2 kA, so confirm your available fault current if using this breaker on a 690 V system.
That 105 mm width for a 3-pole MCCB at this rating is standard for the SENTRON 3VA platform, so it fits existing panel layouts and busbar systems designed for that footprint. The depth of 86 mm leaves room for rear-connected busbars or cable lugs in a typical distribution enclosure.
