GE Industrial Solutions Power Break Stationary Conversion Kit User Manual

DEH 41502 PBI - PBII Stationary Conversion Kit Instruction R01
Overview
The Power Break Stationary Conversion Kit provides all the necessary parts and information to assist in the replacement of a Power Break I stationary circuit breaker with an equivalently rated Power Break II stationary circuit breaker (refer to Table 1). This instruction manual describes the modifications that need to be performed on the equipment and breaker for installation. For complete Power Break II installation and operation instructions, refer to the GEH6279 instruction manual.

Breaker Installation
Ensure that all accessory connections are secure. Line up mounting holes with enclosure. Place the bolts and tighten to 300 in-lbs.
1600–2000A Stationary Breaker
In order to make the conversion to a 1600A or 2000A Power Break II breaker, four modifications are required. Begin process by removing existing breaker from equipment.
Panel Cutout
Figure 2 shows the 14” x 10” cutout required using the existing cutout as reference (dashed). Once cutout is complete, mount the standard trim plate using #8-32 screws and torque to 5 in-lbs.
The 800A Power Break II design is similar in dimension to the 800A Power Break I breaker. The only modification required is the panel cutout. Begin process by removing existing breaker from equipment.
Panel Cutout
A 14” x 10” cutout is required for the Power Break II breaker to fit. Figure 1 shows the new front panel cutout using the existing cutout as reference (dashed line in Figure 1). Once cutout is complete, mount the standard trim plate using #8-32 screws and torque to 5 in-lbs.

Mounting Hole Relocation
Line Shield
Since the mounting holes for the Power Break II breaker do not align with the holes in panel, new mounting holes need to be drilled on the panel breaker mounting space. Figure 3 shows the new locations for the 1600A-2000A breakers. A 1:1 scale template is provided with the kit to guide in the drilling of the holes, which should be made for a ¼-20 tap. It is important to note that new non
magnetic mounting boards or channels may need to be installed in the existing housing to accommodate for the relocation of the mounting holes.
Due to the addition of the strap extensions, a shield is required in the line side of the breaker. To install, place line shield so that the top of mounting bracket aligns with where breaker base and mid cover meet. Mark the area to drill using a drill or white pencil (Figure 5).
Figure 5: Mark the Area for Drilling Holes
After marking the area, drill the holes to a depth of approximately 0.75” using a 0.156” bit. Finally install the line shield using #10-16 thread cutting screws provided (Figure 6).
Figure 3: 1600-2000A Mounting Hole Relocation
Line /Load Strap Extensions
The Power Break I 1600A and 2000A breakers are longer than their Power Break II counterparts. To compensate for the difference in length, 6 line strap extensions are provided with the conversion kit. Please note that the length for the straps is different, 1600A is 4” long and 2000A is 5.25”. Bolt the extensions using 1/2” screws to the line and load straps to a torque of 300 in-lbs. The extensions should be bolted as shown on Figure 4.

Breaker Installation
Ensure that all accessory connections are secure. Line up mounting holes with enclosure. Place the bolts and tighten to 300 in-lbs.
Neutral Sensor
For Power Break I connected in a three-phase four-wire system please note the following regarding neutral sensor:
- If the Power Break I has an Enhanced MVT Plus/PM trip unit, the neutral sensor can be reused
- If the Power Break I has an Original MVT, RMS-9, or EPIC trip unit, the neutral sensor can be reused. However, a 1:1 isolation CT might be required to properly isolate from multiple grounds.
- For Power Break I with any other trip unit, the neutral sensor must be replaced. See Page 31, GET­8052C for Neutral Sensor Options.

2500-4000A Stationary Breaker
Breakers with a frame size from 2500A to 4000A are considered large frame. They include the 2500A front connected (FC), 2500A back connected (BC), 3000A FC, 3000A BC, and 4000A FC. As in the case of the 800A breakers, the Power Break II designs are similar in dimensions to the Power Break I breakers. Only the panel cutout needs to be modified to be ready for breaker installation. Begin process by removing existing breaker from equipment.
Panel Cutout
The 2500A FC, 2500A BC, 3000A FC, and 3000A BC require a 14” x 16.07” cutout for the Power Break II breaker to fit. Figure 8 shows the new front panel cutout using the existing cutout as reference (red line in Figure 7).
Trim Plate
Once cutout is complete, mount the provided trim plate using #8-32 screws and torque to 5 in-lbs. Please note the trim plate is determined by the Power Break I that is to be replaced. Figure 9 shows the 2 types of trim plates used in large frame breakers. If the equipment had an electrically operated Power Break I, SSF40TPCCE kit should be used (left). If the breaker was Manually operated, use SSF40TPCCM kit (right).

Figure 7: 2500A FC, BC, 3000A FC, and BC Panel Cutout
The cutout for the 4000A breaker should be 14” by 13.54” and it is shown in Figure 8.

Breaker Installation
Ensure that all accessory connections are secure. Line up mounting holes with enclosure. Place the bolts and tighten to 225 in-lbs for 2500-3000A breaker, or 300 in-lbs for a 4000A.
Neutral Sensor
For Power Break I connected in a three-phase four-wire system please note the following regarding neutral sensor:
- If the Power Break I has an Enhanced MVT Plus/PM trip unit, the neutral sensor can be reused
- If the Power Break I has an Original MVT, RMS-9, or EPIC trip unit, the neutral sensor can be reused. However, a 1:1 isolation CT might be required to properly isolate from multiple grounds.
- For Power Break I with any other trip unit, the neutral sensor must be replaced. See Page 31, GET­8052C for Neutral Sensor Options.
