GEH3417 INSTALLATION INSTRUCTIONS FOR RIGHT POLE MOUNTING ONLY

• Molded Case Circuit Breakers
• Under voltage Release for Type: TED

CAUTION : Before inspecting or beginning any maintenance work on the breaker, it must be dis­connected from all voltage sources, both power and control, and breaker must be off (open).

1. NOTES: 1. Any work requiring cover removal of a sealed breaker voids UL listing. The UL label must be destroyed.
2. UVR cannot be installed in breakers code dated with this number or lower: 101

ELECTRICAL DATA

Kit includes special externally mounted resistor.

ALL RATINGS CONSUME 2.2 WATTS EXCLUSIVE OF RESISTOR

DESCRIPTION

This device is used for automatic breaker tripping when line voltage drops below a pre-determined level.

1. STEP 1
   BREAKER PREP ARA TI ON-FOR FIELD INSTALLATION.
   Open breaker contacts by moving handle to the breaker “OFF” position.
   Remove breaker cover by removing cover screws as shown in Figure 2. (Care must be taken when opening the TB1 as the button shown in Figure 8 may pop out.) Tar must be removed and discarded to gain access to screw shown in Figure 2. Remove and save plastic handle.
   Push trip bar towards line end to trip mechanism. (See Figure 3.)
   

2. STEP2
   MODIFYING COVER
   Perform cover modification as shown in Figure 4.Remove all debris.
   

3. STEP3
   MODIFYING TWIST TO TRIP FEATURE
   Assembly of the Under voltage Release in the right side of the breaker immobilizes the Twist to Trip feature. Place the enclosed label P/N 331A3044P1 over the Twist to Trip feature button as shown in figure 5. Perform inside cover modification to remove the legs of the Twist to Trip feature (trim even with the Twist to Trip Button) and avoid potential interference with the Undervoltage Release. The trip functionality previously provided by the Twist to Trip feature con be obtained through removal of control voltage to the Under voltage Release.

4. STEP4
   REPLACING BARRIER
   Remove barrier between right pole and mechanism pole, and replace with barrier supplied with kit. Locate projection of new barrier toward load end of breaker. (See Figure 6.)

5. STEP5
   INSTALLATION

   • Move the handle toward the line end of the breaker to facilitate assembly. Be sure locating tab is plugged into positioning hole in base. (See Figure 7.)
   • The pre-positioned coil leads should be close to the current location to fit the notch in the cover.
   • Be absolutely sure to reinstall in their proper location barriers or other parts accidentally removed from the breaker. Reinstall plastic breaker handle (white line towards breaker load end).
   • Install breaker cover making sure no wires are pinched in the process. Install cover mounting screws and apply label to breaker side.
   • Note that on TB1 breakers the second barrier shown in Figures 8 and 9 must be installed
     MOVE HANDLE TOWARDS LINE END .
     

6. STEP 6
   PERFORMANCE CHECK

7. Move breaker handle to “OFF” position to reset breaker.

8. With coil deenergized, move breaker handle towards “ON” position. Breaker should trip and handle should come to rest in the tripped position when released.

9. Apply 80% of rated voltage to coil (use dropping resistor if required). Repeat Step 1, then move handle to “ON” position. Breaker should turn “ON” and stay “ON”.

10. Reduce coil voltage. Device should trip breaker between 35% and 70% of rated voltage.
