The Ralli Wolf SPM 25 is a special purpose motor built for circuit breaker applications, running on a 220V AC or DC supply. It combines a high no-load speed with a substantial full-load current draw, giving it a distinct performance profile from the other motors in the SPM range.

Under no-load conditions, it spins at 15,000 RPM while drawing 0.75A and 156W. Under full load, speed settles to 5,500 RPM while current rises sharply to 3.0A and input power to 550W — a larger jump in power draw between no-load and full-load states than seen in the SPM 18 or SPM 23, suggesting the SPM 25 is built to deliver stronger torque under load rather than simply maintaining high speed.

Its full-load rating of 1 minute puts it in the same short-burst duty category as the SPM 23, designed for quick, momentary operation within a circuit breaker mechanism rather than sustained running. Combined with its higher power draw under load, this points to a motor built for a brief but forceful action — such as a rapid trip or high-force operating function — within the breaker's switching mechanism.
