Installation and operation instructions

Installation

Can be installed in any mounting position due to snap-on fixing to DIN rails EN 60 715, 35 mm width.

A If MCB S 200/S 200 M is installed without cross wiring, hinge the upper part into the DIN rail and push to let the lower part of the device snap

into place (1). The device is released in the reverse order, after the quick fastener has been removed with a screw driver (2).

B To release S 200 /S 200 M that are cross-wired with System pro M compact busbars, first remove the clamping screws Then, pull the lower

part of the S 200/S 200 M forwards (1) and lift it straight up (1a) , then, the quick fastener (1b) will recede.

C The busbar is deallocated and the S 200/S 200 M can be pulled out by lifting the device forwards (2).

D The cross-wiring is re-inserted in the reverse order. First, open the clamping screws and pull out the quick fastener until it locks into place

for the first time (3) . Then, take the S 200 /S 200 M and insert it with rear terminal side onto the pins of the System pro M compact busbar

(4) , turn it into the direction of the DIN rail (4a) and shift it vertically downwards (4b) ,this way, the quick fasterner snaps back into place

(4c).

Attention: Do not forget to re-tighten the clamping screws.

Operation

MCBs are switched on by switching the operating lever into the upper position (with resepct to the text block of the nameplate). If an MCB,

after it has triggered, cannot be switched on again off-handedly, the triggering is probably caused by overload.

If the MCB trips again immediately when trying to reclose (let a short period of time elapse), a complete short-circuit, or as the case may

be, earth connection can be assumed.

Do not try and continuously re-close an existing short circuit or earth fault. The MCB even trips under overload, or short-circuit or earth

fault conditions, even if the operating lever is maintained in the ON position by force (trip-free mechanism).

Cleaning the device

MCBs soiled by installation work should be cleaned with a dry, or, if necessary, a damp and soapy cloth. Never use caustic agents or

dissolvents.

Maintenance

STOTZ MCBs are maintenance-free.

Opening the device will lead to a loss of warranty.
