Its Class 10 trip characteristic means it opens within 10 seconds at 7.2× the thermal setting — fast enough to protect standard IEC motors during a locked-rotor event. The interrupting capacity of 100 kA at 400 V AC means it can safely clear a bolted fault up to that level without requiring an upstream current-limiting fuse in most panel designs, simplifying coordination. Phase failure detection is built in, so a lost phase on the line side trips the breaker before single-phasing damages the motor windings. ## Mounting and wiring — panel integration Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The 45 mm width is a standard 2-module footprint — fits alongside contactors and overloads in a motor starter row without crowding. Depth of 97 mm leaves clearance for wiring ducts; the spring-loaded terminals on the main circuit accept 2× (0.5 to 4 mm²) solid or stranded conductors, so no ferrule crimping is required for the line and load connections. Mounting position is any orientation, which helps when the panel layout is tight.","metaTitle":"Siemens 3RV2011-1DA20-ZW96 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2011-1DA20-ZW96 motor protection circuit breaker.

However, the -1DA20-ZW96 carries a 100 kA interrupting rating at 400 V versus the -0BA20's lower rating — verify the panel's SCCR requirement before substitution. The -0BA20 is a different thermal setting range, so the overload protection curve will differ."},{"question":"What compliance documentation does Siemens provide for this breaker?","answer":"The evidence does not list specific certifications (UL, CSA, CE, RoHS, REACH) for this order code.
