A Quick guide to the types and details of motor starters.
What is the ‘ EI ‘ electronic interface function? And – how does it work on the CA9 contactors?
Are there options to use / or not use the ‘ EI ‘ electronic interface functionality on the CA9 contactor?
What cover controls do KWIKstarters have? Why can’t I have an HOA or Pilot Light only on the larger KWIKstarters? What does the wire size have to do with the cover control options? What is the difference between remote control and without remote control? The cover control options for these compact starters vary depending on the KWIKstarter size and function. .

The increased use of high efficieny motors requires a closer look at specifications when applied to circuit protection methods. Not considering all of the factors can lead to specification errors and nuisance tripping or worse.
The SCCR values for the CEP9-ESM Sensing modules can be found in the installation instructions included in the box. This is the manner in which UL requires the SCCRs to be specified.
One of the outstanding features of IEC type overload relays is protection of three phase motors in the event of a single phase condition; otherwise known as “open phase” or “phase failure “ in one of the motor leads.
