Description

S2 – serial code:

S 2 C - S/H 6 R

R = right side-mounted

6 = change over

H = auxiliary switch

S = signal contact

C = compatible to pro M compact

S2C-S/H6R is a universal device complementing the range of pro M compact, which is supplied to offer signal contact functionality,

or the auxiliary switch can be activated, all you need is a screwdriver. The universal switch can be with MCBs and RCCBs.

Up to three S2C-H6R can be mounted (one signal contact max. fitted to MCB or RCCB). Both the switchgear and the S2C-S/H6R must

be in the ON end position to ensure that the coupling is correct.

Function of the signal contact S

Signal is transmitted only if caused by fault-tripping of the circuit-breaker, but not if the switch has been switched on or off manually.

Press the orange reset button to acknowledge the has-tripped signal.

Function of the auxiliary switch H

The switch always indicates the switching position of the MCB, irrespective of whether the switching position is attributable to manual

operation or fault tripping.

Functionality selection

To select either the signal contact function S or the auxiliary switch H, use a screwdriver and adjust to position S, or as the case may be, H at

the side of the device.
