The Ralli Wolf SPM 24 is a special purpose motor built for circuit breaker applications, running on a 235V AC or DC supply. Unlike the higher-speed SPM 18 and SPM 23, the SPM 24 operates at a much lower speed range, making it suited to a different class of circuit breaker function where controlled, lower-RPM operation matters more than rapid speed.

Under no-load conditions, it draws 0.6A and 130W at 2,800 RPM. Under full load, current rises to 1.15A and input power to 235W, with speed settling to 1,500 RPM — a modest, controlled output profile compared to the 9,000-18,000 RPM range of the other SPM motors in the range.

Its full-load rating of 30 minutes marks a significant step up in duty cycle from the SPM 18 (10 minutes) and SPM 23 (1 minute), pointing to a motor designed for longer, more sustained operation within a circuit breaker mechanism — likely suited to a different stage of the switching or charging process than its faster, shorter-duty siblings.
