Replacing Current Transformers (CTS)
The CTs are mounted in the circuit breaker compartment. To
access the CT assembly, de-energize SecoGear, open the front
door, and remove the SecoVac VCB.
1. Prepare the CT for mounting by verifying the following items
before proceeding:
• Ratio
• Polarity
• Category number
• Orientation per line diagram
2. Carefully raise and position the CT into the circuit
breaker compartment.
3. Push the CT onto the spout until it is flush with the rear
of the assembly (Figure 9-2). Repeat for any additional CTs.
4. Install spacers behind CTs (Figure 9-4). Apply 7/8” spacers to
single CT modules; apply 7/8” and 2” spacers (Figure 9-3) to
piggyback CT modules.
5. Secure CTs by installing bolts from the front, torque to
8 ft.-lbs [10.85 Nm].
