The Ralli Wolf SPM 23 is a special purpose motor built for circuit breaker applications, offering compact, efficient power delivery on either 220V AC or DC supply. Its dual voltage compatibility gives manufacturers and maintenance teams flexibility to use the same motor across different power configurations without needing separate variants.

Under no-load conditions, the SPM 23 draws just 0.58A and 124W while spinning at a very high 18,000 RPM — faster and more efficient at no-load than the SPM 18. Under full load, current rises to 1.2A and input power to 230W, with speed settling to 9,000 RPM, giving it lower power draw across the board than its SPM 18 counterpart.

Its full-load rating of just 1 minute marks the SPM 23 as built for very short-burst, intermittent duty — even briefer than the SPM 18's 10-minute rating. This points to a motor designed for quick, momentary operations within a circuit breaker mechanism, such as a rapid spring-charge or trip function, rather than sustained running.
