* A linked contact is a mechanism found mainly in auxiliary relays. (Applicable models: J73KCA-31, J73KCA-22)
With the combination of the auxiliary circuit of the main unit, welding the NO (or NC) contacts will result in a structure that secures a shock resistance voltage of 2.5 kV or more, or a contact interval of 0.5 mm or more, for the NC (or NO) contacts even if the excitation of the coil is released. No linked contact structure is created with the combined usage of the auxiliary contact unit (J73KC-AM).
