The Siemens 3RV2411-1AA10-Z W97 is a SIRIUS 3RV2 motor starter protector in frame size S00, configured specifically for transformer protection. Its A-release is set at 1.1...1.6 A with a short-circuit release at 33 A, and it uses screw terminals with standard switching capacity. This variant ships in multi-unit packaging of 12 pieces.
The A-release range of 1.1...1.6 A defines the continuous current the breaker will carry without tripping — sized for the transformer's rated primary current, not the motor full-load amps. The fixed short-circuit release at 33 A provides instantaneous trip on a fault, protecting downstream windings. Frame size S00 is the smallest in the 3RV2 family, fitting standard DIN-rail mounting in control panels where space is tight.
