Specifications

Overcurrent trip system	If the relay trip system of a circuit breaker is a current transformer secondary current trip system, when a fault current is detected by the instantaneous element of the relay and is cut off, the large current in the secondary circuit of the current transformer will be cut off at contact point b of the relay and contact point b may be damaged. The risk of damage will be high; especially if the pr
Device combinations: Circuit breaker	VF-8□H-D/DG , VF-13□H-D/DG (equipped with overcurrent trip equipment)
Device combinations: Overcurrent trip relay	Static type , Model MOC-A1T-R
Device combinations: Current transformer: Rated burden	10VA
Device combinations: Current transformer: Model name	CD-10CNB
Device combinations: Current transformer: Rated primary current (*1)	20A
Current transformer applicable burden (VA) (*2)	9 to 10
Note	(1) When the primary current of current transformer is 40A or less, the voltage trip system (capacitor trip system) is recommended. (2) If the load used is less than the rated load, please use the T-100L load regulator (the load used can be adjusted to 2, 4, 6, or 8VA).

Specifications

Voltage trip system	The reliability of the overcurrent relay can be improved by using the voltage trip system (capacitor trip system) for the circuit breaker.

Note	(3) The part of the name shown by □ depends on the mounting method. (4) If the load used is less than the rated load, please use the T-100L load regulator (the load used can be adjusted to 2, 4, 6, or 8VA).

Specifications

Specifications	This load regulator should be used if the load for connected to the secondary circuit of the current transformer is below the range of applicable load required for the transformer (refer to the above tables). Be certain to use the load regulator for each phase (phase the current transformer is set for) and adjust the usage load to a value that is as close as possible to the rated load.
