Eaton S611 Series current transformer kits are suitable for use with S611 Series soft starters. Current transformers (CTs) are designed to monitor the current flow in electrical devices and step down high currents to a lower, measurable range. They also provide electrical isolation and accuracy in current measurement. CTs can be integrated into the soft starter to provide overload protection for the motor. With continuous monitoring, they can detect excessive currents that might potentially damage the motor. These UL-listed current transformer kits are available in A/B, C/D & E/F type frames for protection against impact damages and mechanical stresses.
