The Ralli Wolf SPM 18 is a special purpose motor designed specifically for circuit breaker applications, where compact power delivery and dual voltage compatibility matter. Running on either 220V AC or DC supply, it offers flexibility for manufacturers and maintenance teams working across different power setups without needing separate motor variants.

Under no-load conditions, the SPM 18 draws just 1.1A and 230W while spinning at a high 15,000 RPM. Under full load, it draws 2.8A and 580W, with speed settling to 9,200 RPM — a performance profile suited to the kind of intermittent, high-speed operation typical in circuit breaker mechanisms, such as spring charging or operating motor functions.

Its rating of 10 minutes at full load indicates this motor is built for short-duration, intermittent duty cycles rather than continuous running — standard for motors used in circuit breaker operating mechanisms, which typically only need to run briefly to charge a spring or complete an operating cycle before resting.
