Please be informed that the data shown in this PDF document is generated from our online catalog. Please find the complete data in the user documentation. Our general terms of use for downloads are valid. 

Disconnect terminal block, nom. voltage: 24 V, nominal current: 41 A, connection method: Screw connection, Rated cross section: 6 mm[2] , cross section: 0.5 mm[2] - 10 mm[2] , mounting: NS 35/7,5, NS 35/15, NS 32, color: gray 

## Your advantages 

- Once the disconnect slide has been opened to the "off" position, the red light indicates whether there is a ground fault in the control circuit 

- When the disconnect slide is closed, switch position "on", the yellow light indicates grounded normal operation
