The Ralli Wolf UM 26 is a high-speed universal motor built for circuit breaker applications, running on a 220V AC or DC supply. It's designed for rapid, short-burst operation — a profile suited to fast-acting circuit breaker functions like spring charging or trip mechanisms that need to complete their action almost instantly.

Under no-load conditions, it spins at a very high 29,000 RPM while drawing 0.8A and 100W. Under full load, speed drops to 20,000 RPM while current rises to 1.1A and input power to 200W — still an exceptionally high speed range compared to most of the SPM circuit breaker range, putting the UM 26 among the fastest motors in Ralli Wolf's switchgear motor lineup.

Its 1-minute duty rating at both no-load and full-load confirms this is built for very brief, high-speed bursts rather than sustained running — consistent with a motor designed to execute a single rapid mechanical action within a circuit breaker before returning to rest.
