The Ralli Wolf UMG 31/32 is a reversible universal geared motor built for circuit breaker applications requiring bidirectional operation — capable of running clockwise or anti-clockwise depending on the mechanical function needed. This reversibility makes it suited to circuit breaker mechanisms that must both charge and release, or open and close, using a single motor rather than separate directional components.

Running on a 230V AC or DC supply, it draws 1.35A and 150W at no load, spinning at 700 RPM. Under full load, current doubles to 2.7A and input power to 300W, while speed drops to 300 RPM — a substantial speed reduction under load that reflects the motor delivering higher torque as resistance increases, consistent with driving a mechanical charging or operating mechanism against spring resistance.

As a geared motor, it sits between the high-speed ungeared UM motors and the very low-speed UMG 14 in Ralli Wolf's range, offering a moderate speed output with reversible direction — a combination suited to circuit breaker operating mechanisms that need controlled, two-way mechanical drive rather than a single fast burst in one direction.
