The disconnect switch element can be used to cre-ate an interlocking functionality. For greater security in determination of the switch pole position, both the 52/a and 52/bauxiliary contacts are used with reporting of the discrepancy between them. The number of available disconnect switchesdepends on the number of the CT/VT modules ordered with the L90.• SWITCH 1 FUNCTION: This setting enables and disables the operation of the disconnect switch element.• SWITCH 1 NAME: Assign a user-defined name (up to six characters) to the disconnect switch. This name will be usedin flash messages related to disconnect switch 1.• SWITCH 1 MODE: This setting selects “3-Pole” mode, where all disconnect switch poles are operated simultaneously,or “1-Pole” mode where all disconnect switch poles are operated either independently or simultaneously.
