Jaguars do not have an internal breaker they have an over current sense which shuts down the output during a perceived fault. The Jags have a 15kHz switching frequency while the Victors have a 150 Hz switching frequency. This difference allows the output pulse to interact with the motor inductance to produce a smoother but less powerful motor response at low throttle levels. This phenomena while allowing a more controlled movement also produces less motor power for a given throttle value below about 60-75% of full throttle.

The Spike is simply two relays inside one case. They can be commanded in such a way that the output can be full on in either direction or each output pin can be controlled independently.
