Tri-Phase and Tri-Phase with Ground Trip (TPG) Controls

These controls are used in conjunction with Kyle Type VFI fault interrupting switchgear and Pad-mounted Source Transfer (PST) units. Coordination and application of the controls are identical to expulsion fuse application, but with the benefit of greatly expanded trip rating and timing curve selections. Minimum-trip settings for each phase are DIP switch selectable, allowing convenient configuration to meet your specific application requirements.
