Many applications require several steps using different current start levels and time
delays. EFxPTOC consists of three different protection stages.
• Low EFLPTOC
• High EFHPTOC
• Instantaneous EFIPTOC
EFLPTOC contains several types of time-delay characteristics. EFHPTOC and
EFIPTOC are used for fast clearance of serious earth faults.
