Disconnect terminal block, nom. voltage: 250 V, nominal current: 41 A, 1 level, 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 

- 

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

- 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
