EOCR-3DM2/EOCR-FDM2 Protection Project

Protection project	Setting range and conditions	Action time
Overcurrent	When the current value on the load exceeds the set current value: Setting range: 0.5 to 60 A (definite time limit) 　　　　　0.5 to 32 A (inverse time limit)	Time limit: between 0.2 and 30 seconds
Overcurrent		Inverse time limit & overheating inverse time limit: 1~30 Class
Undercurrent	The undercurrent set value cannot exceed or equal to the overcurrent set value when the current value on the load is lower than the set undercurrent value.	OFF, adjusted between 1 and 10 seconds
Reverse phase	This option can be used when the phase sequence reciprocal of the three-phase current is used .	Within 0.15 seconds
Stall	This value is set to several times the overcurrent set value. It is only suitable for the start-up process and its setting range can be adjusted. 0.5 to 30A: 2 to 8 times to 40A of overcurrent setting value : 2 to 6 times to 60A: 2 to 4 times	After D-Time time (within 0.5 seconds)
Stall	This value is set to several times the overcurrent set value. It is only suitable for operation and its setting range can be adjusted. 0.5 to 50A: 1.5 to 5 times to 60A ofthe overcurrent setting value : 1.5 to 4 times	Adjust between 0.3 and 5 seconds
Phase imbalance	Condition: Current imbalance ≥ setting imbalance % Setting range: 10 to 50% imbalance	Adjust between 1 and 10 seconds
Ground	Condition: Ground current setting range when the ground current setting value is exceeded : OFF, 0.05-10A	Adjust between 0.5 and 5 seconds -- 3MZ2/FMZ2 only --
