190E-AND2-CB16X

The 190E motor controllers can be used in a variety of applications. These starters can be used in a group motor application or as a stand-alone product without any additional short-circuit protection in the motor branch circuits. Most of the 140M-C/D motor protection circuit breakers used in the 190E/191E starters are UL Listed as a manual Type E self-protected combination motor controller. Although there are many tests involved, one of the critical tests a self-protected combination motor controller must pass is to perform 6000 electrical ops. and an additional 4000 mechanical ops. after a short circuit. By definition, a Type F combination motor controller consists of a Type E manual self protected combination motor controller and a magnetic or solid-state motor controller (such as a 100-C contactor or an SMC). As with a manual Type E self-protected combination motor controller, additional short-circuit protection is not required for the individual motor circuits. A combination of a 140M manual self protectd combination motor controller and 100-C contactor can be listed as a Type E self-protected combination motor controller. In this case, the 140M and 100-C must pass the additional 6000 electrical and 4000 mechanical operational test. In some cases, this may require over sizing of the 140M motor protection circuit breaker or the 100-C contactor to achieve weld-free performance and meet the additional life requirements.
