Estimated Time to Complete Tasks

It takes about 15 minutes to install or replace the assembly.

General Description

For the retrofill, the following information is for either installing or replacing the mechanism for the position switch (not the position switch itself) on the retrofill circuit breaker; the position switch assembly is already mounted in the compartment; if not, it can be ordered as an option. The mechanical subassembly is a simple ancillary lever-and-tension device that pushes against the position switch arm when the retrofill breaker is racked in completely. This device, mounted on the cassette using simple hardware, is called the actuator or actuator bracket. Its purpose is to make a strong contact with the position switch when the racked-in breaker provides mechanical pressure against the arm. The mechanical force on the lever and tension mechanism then activates the position switch. The position switch, when activated, determines that the racked-in circuit breaker is connected.

Figure 1 is an example of an installed position switch. It is activated mechanically when the breaker is racked in.

The mechanical subassembly comes with mounting hardware, lever, and bracket. Depending on the switchgear, this simple device is mounted in different locations.

• Turn off all power to switchgear. Tagout and lockout main source, up-stream or main breaker.

• Failure to comply with these instructions will result in death or serious injury from severe burns caused by arc flashing that has exceedingly high temperatures.

• Always wear personal protection equipment

according to OSHA standards and appropriate

to the severity of potential burns.

• Ensure only qualified personnel install, operate, service, and maintain all electrical equipment.

Compartment Switch Options

Available as an option for mounting within the base of the cassette/substructure or compartment, the position switch provides six single-pole changeover contacts for local or remote electrical indication of the circuit breaker status: CONNECTED, TEST, and DISCONNECTED. The DISCONNECTED position is indicated only when the minimum isolating distances between contacts on both the main (primary disconnects) and auxiliary (secondary disconnects) have been achieved. This option is in addition to the mechanical indicators, which are fitted as standard components. When installed, the switch is IP2X-protected and includes wiring to a terminal block on the left side of the cassette. Table 2 displays the available normally-open and normally closed switches. The ratings for position switches are shown in Table 3.

AKD-5—AK25 Position Switch Actuator

Description

The position-switch actuator assembly for the AK25 should be mounted on the bottom plate of the cassette assembly of the AK25 retrofill. The actual actuator assembly consists of two plates, one each on the top and bottom of the baseplate. The top plate of the actuator interfaces with the breaker when it is racked in and its motion is transferred to the bottom plate, which interfaces with the position switch lever on the legacy compartment.

Completing the racking in of the EntelliGuard breaker into the cassette corresponds to the end-of-stroke of the

positionswitchsysteminthecompartmentforAK25inAKD-5LVS.Figure 2 shows the exploded view of the AK25

retrofill position-switch actuator (actually a bracket assembly); Figure 3 displays the assembly from the bottom.

Note: While racking the EntelliGuard ACB breaker into the cassette, while actually racking in the breaker, the position

indicator window begins to read “connected”. This position indicator means that the retrofit system has activated

theexistingpositionswitchintheLVS.

Installing the position switch actuator needs to be done before the cassette is racked into the compartment. Steps for installing the position switch actuator are as follows:

1. Place the retrofit EntelliGuard ACB cassette assembly for AK25 on an elevated surface, such as a table, to mount the position switch actuator assembly on to the base plate. Sufficient space should be available at the bottom of the cassette and the mounting table to provide easy access for inserting the 3-pin bracket from the bottom.

2. Unpack the position switch actuator components and mount them as shown in the exploded view in Figure 4.

3. Insert the 3-pin bracket from the bottom of the base of the cassette assembly, such that the two pins are within the longer slot and the single pin goes inside the smaller slot of the plate.

4. PlacetheL-bracketfromthetopofthecassetteassembly,suchthatthepinsfromthebottom3-pinplate get inserted into the top plate.

5. Secure the connection by fastening the nuts and washers provided in the actuator kit.

6. Mount the extension springs between the groove of the pin on this actuator assembly and the fixed pin

provided on the cassette base plate.

7. Check that the position switch actuator on the cassette is now installed and ready to function as the breaker is being racked in the compartment.

8. Mount the cassette assembly on the rails of the AK25 cabinet in the AKD-5 and rack the cassette into the

compartmentoftheAKD-5LVS.

AKD-5—AK50 Position Switch Actuator

Description

The position switch actuator assembly for the AK50 should be mounted on the bottom right side of the cassette assembly of the AK50 retrofill. The actuator assembly consists of a linkage system that interfaces with the racking shaft assembly at one end and the position switch actuator arm at the other. Completing the racking in of the EntelliGuard breaker in the cassette corresponds to the end-of-stroke of the position switch system in the

compartmentforAK50inAKD-5LVS.

DEH-41530 02/12

Position Switch Kit for Retrofill CB

Figure 5, below, shows the AK50 position switch actuator assembly in an exploded view. The position switch actuator

for the AK50 is a field-fit type of assembly and is assembled on the retrofill cassette before inserting the cassette into the compartment of the AKD-5.

It needs to be ensured that the cassette is in the “disconnected” state. This can be verified by checking the racking position status in the window located at the right side window, located on the frame of the AK50 retrofil cassette, placed at the front. The position-switch actuator kit for the AKD5-AK50 retrofits needs to be installed on the bottom rear side of the right side sheet of the AK50 retrofit cassette.

This installation can be done by placing the cassette on a work table. The cassette should be placed such that there is enough overhang of the side where there’s room to insert the position switch actuator components from underneath. Alternately, the installation can also be achieved by placing the cassette assembly on the retrofit AK50, that is, on the telescopic rails of the AKD5 compartment that is being retrofit.

Installation

1. Once the access for installing the position switch actuator is achieved, slide the assembly up from the bottom

of the cassette. When inserted, the plate is placed on the outside of the cassette side sheet and the movable flaps are on the inside.

2. Lineuptheholesonthecassettesidesheetwiththeholesontheactuatorassembly.

3. Fasten the three M6-bolts and 6-mm washers, provided with the actuator assembly, to the three holes on the

cassette side sheet. Two holes are placed on the side and one hole on back of the cassette assembly.

4. Check that the position switch actuator on the cassette is now installed and ready for use as the breaker is being racked into the compartment.

5. Mount the cassette assembly on the rails of the AK50 cabinet in the AKD-5 and rack the cassette into the

compartmentoftheAKD-5LVS.
