①Main circuit current choosing: When the number of main circuit is 2~3 poles,the current of no isolated type is 10~30A, the current of isolated type is 10A.When the number of main circuit is 1,the current of no isolated and isolated type can choose 10~30A.
②HRC3 has maximum 4 output passageway:Main Arc-less circuits: 3 Auxiliary circuit: 1 If main-circuit used only 1 or 2 circuits, the rest can be used as auxiliary contacts base on per customer’s requirement. Exp. 1: 2N1C required Model Number: HRC3G30A250VI-2N1CD24 Exp. 2: 1N1C ModelNumber: HRC3G30A250VI-1N1CD24 Auxiliary contacts ratings: N (Normal Open) 5A, 277VAC / 5A 28VDC C(Normal Close) 2A, 277VAC / 2A 28VDC;
③ Control coil voltage recommendation: 2-3 phase: DC 5V, 6V, 9V, 12V, 15V, 18V, 24V, 48V. (Recommend 24VDC)can be choosed.. 1 phase: AC 12V, 15V, 18V, 24V, 48V, 70V, 110V(Recommend 110V), 120V, 220V( Recommend 220V)can be choosed.
