GE Industrial Solutions Power Break II Hidden on Button - Manual

Introduction
The Hidden On Button, catalog number SPPBNONR, can be
installed on 800–4000 ampere-frame Power Break® II circuit
breakers. The kit consists of an unmarked replacement for the
normal On button and a plastic button that attaches to the
breaker mechanism.
Operation
Charge the breaker closing springs, then insert the end of an
approximately 0.1-inch-diameter steel rod through the hole in
the center of the Hidden On Button, as shown in Figure 1.
When the rod engages the button attached to the mechanism,
light pressure on the rod will close the breaker mechanism.

Installation
WARNING: Before installing any accessories, turn the breaker
OFF, disconnect it from all voltage sources, and discharge the
closing springs.
AVERTISSEMENT: Avant d’installer tout accessoire, mettre le
disjoncteur en position OFF, le déconnecter de toute tension
d’alimentation, et décharger les ressorts d’armement.
Use the following procedure to install the Hidden On Button:
1. If a trim plate is installed on the breaker, loosen the four
screws securing the trim-plate assembly and remove the
trim plate from the breaker.
2. Loosen the four screws at the corners of the breaker
cover. Pull the operating handle down and hold it
extended, then remove the cover.
3. Locate the tab on the breaker mechanism that is
normally engaged by the on button, shown in Figure 2.

4. Slide the slot on the white plastic button, supplied in the
Hidden On Button kit, over the tab on the lever that
closes the breaker, as shown in Figure 3. Push the button
to the limit of the lever’s travel to ensure a tight fit.
CAUTION: If the white plastic button is not fully seated on the
tab on the breaker-closing lever, the breaker interlocks will not
function.
ATTENTION: Les mécanismes de verrouillage du disjoncteur
ne fonctionneront pas si le poussoir de plastique blanc n’est pas
complètement enfoncé sur l’attache du levier de fermeture de
l’interrupteur.
5. From the back side of the breaker cover, use two
screwdrivers to press in the locking tabs on the ends of
the normal On button, as shown in Figure 4, then push
the button out through the front of the cover.
