special, indirect, incidental or consequential damage or loss whatsoever, including but not limited to damage or loss of use of equipment,

of Type LV-VSR, Low Voltage- Vacuum Starter Replacement Units.

These units are horizontal, draw-out type removable Vacuum Starter

Replacements for existing LV Metal-Enclosed Switchgear with

breakers of the same type and rating. LV-VSRs provide reliable

control, protection, and performance, with ease of handling and

maintenance.

This booklet is intended to be used in conjunction with the technical

information provided with the original equipment order that includes

but is not limited to electrical control schematics and wiring

diagrams, installation plans, and procedures for installation and

maintenance of accessory items.

Satisfactory performance is dependant upon proper application,

The current limiting fuses, class J (sized as required), are primarily

used to provide short circuit protection to the vacuum contactor.

During High-Power testing, the V201 vacuum contactor was

confirmed to properly coordinate with Mersen class J AJT600EIB

current limiting fuses. The contactor successfully withstood the

let-though energy of each fuse for a 200 kA available symmetrical

fault at 600 Vac. Other UL Class J fuses can be specified by the

end user, as required, for proper coordination. Their let-through

current, however, must be less than the short circuit current

standard with Trip Class 10 and 20 trip characteristics and Manual

or Manual/Automatic Reset. An electro-mechanical overload relay,

Eaton type C306 may be substituted for the electronic overload

relay. This relay is equipped with Class 20 overload relay heaters

sized according to the motor full load current (FLC) and service

factor. This relay has settings to select a trip threshold closest to

the motor FLC; manual and automatic reset modes are selectable.

The V201 Vacuum Contactor is designed for the control of

sequences.

Refer to Table 5.

Indoor storage should be in a building with sufficient heat and

circulation to prevent condensation. If the building is not heated, the

same general rule for heat as for outdoor storage should be applied.

The C440 FLA setting may also be determined from Table 6.

Manual operational checks must be performed before the LV-VSR is

connected to a live circuit. The checks can be performed either with

the LV-VSR in TEST position in the cell or outside of the cell, as long

as secondary power is available.

Check the vacuum integrity of the interrupters of the three vacuum

bottles by conducting the applied potential test described in Section

6.

The LV-VSR can only be operated electrically when the following

condition are met:

To open the LV-VSR, send a remote open signal, press the open

pushbutton, or press the test button on the overload relay.

Perform several close/open operations to ensure reliable and

constant electrical operation.

The LV-VSR is equipped with interlocking for safety during the

insertion and removal process.

contactor is new. If less, refer to the Contact Wear Allowance

section of this manual.

While the contactor is open, attempt to pull the armature forward.

The armature should not move because it should already be firmly

against the plastic main frame. If it does move, refer to the Kickout

Spring Adjustment section in this manual.

The kickout spring is not disturbed by any maintenance described

in this manual and, therefore, should not need any adjustment.

However, when the contactor is in the OPEN position, the crossbar

severe stress, it is recommended that the unit be replaced. If the

over-travel has changed significantly (from the last inspection) on one

or more bottles, the unit should be replaced.

A dielectric test may be performed at 1760 Vac (80% of factory test

level) (see Section 6.6). A dielectric test would not by itself confirm

that the unit should be returned to service after a fault. Vacuum

Integrity is to be performed at 5.5 kVac RMS per Section 6.4.

However, if there is no physical evidence of stress, and if the over-

travel exceeds the 0.020 in. (0.51 mm) minimum, the bottles can

then be dielectrically tested as outlined in this manual. If physical

is dependent upon the integrity of the vacuum in the interrupter and

the internal dielectric strength. Both of these parameters can be

readily checked by a one minute AC high potential test. During this

test, the following warning must be observed.
