Installation Instructions
Bulletin 193 E100 External Current Transformer Overload Relay
Application and Installation
(Cat 193-1EF_Z)
WARNING: To prevent electrical shock, disconnect from power source before installing or servicing. Install in suitable enclosure. Keep free from contaminants.
Follow NFPA70E requirements.
WARNING: Do not use automatic reset mode in applications where unexpected automatic restart of the motor can cause injury to persons or damage to equipment.
WARNING: The improper selection of a current transformer can result in the overload relay not properly protecting the motor and possible motor damage. The selected
current transformer must be rated for protective relaying applications.
At the end of its life, this
equipment should be
collected separately from
any unsorted municipal
waste.

Frequently Answers and Questions
What type of current transformers are compatible with the 193 E100?
The 193 E100 is designed for use with separately mounted, customer-supplied current transformers (CTs). The CTs must be rated for protective relaying applications and have a secondary current of 5A. Refer to the document for specific CT recommendations based on the motor's full load amperage (FLA).
How do I adjust the trip current on the 193 E100?
To adjust the trip current, turn the dial until the desired current is aligned with the pointer. The trip rating is 120% of the dial setting.
What are the different trip classes available on the 193 E100?
The 193 E100 features selectable trip classes, allowing users to customize the protection characteristics based on the application. Trip classes refer to different time-current curves, affecting how quickly the relay trips in response to an overload. The document provides information about different trip classes and their applications.
