External Current Transformers
(for use with Cat. Nos. 193-EC1ZZ1, 193-EC3ZZ, and 193‑EC4ZZ)


The user shall provide one current transformer (CT) for each motor phase,and shall connect the CT’s secondary leads to the appropriate E3 overload relay power terminals, as shown in current transformer’s wiring diagrams. The CT shall have the appropriate ratio (refer to the product nameplate or product description). Additionally, the CT shall be selected to be capable of providing the required VA to the secondary load, which includes the E3 overload relay burden of 0.1 VA at the rated secondary current and the wiring burden. Finally, the CT shall be rated for protective relaying to accomodate the high inrush currents associated with motor startup, and shall have an accuracy of <±2% over its normal operating range. Typical CT ratings include (Instrument Transformers, Inc. — Model #23 or equivalent):

ANSI (USA) Class C5B0.1
CSA (Canada) Class 10L5
IEC (Europe) 5 VA Class 5P10
