FP-25-LV-VSR
Breaker-To-Motor Starter Conversion
SECTION 1: INTRODUCTION
The purpose of this instruction book is to provide instructions for
receiving, handling, storage, installation, operation, and maintenance
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,
correct installation, and adequate maintenance. It is strongly
recommended that this instruction book be carefully read and
followed in order to realize optimum performance and long useful life
of the LV-VSR.
The LV-VSR consists of the following components: Current Limiting
Fuses, Overload Relay, and V201 Vacuum Contactor.
•
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
rating (SCCR) of the V201 contactor.
•
The overload relay provides longtime overload protection and
single-phase protection. The solid-state Overload Relay provides
high accuracy and enhanced protection through the use of micro-
electronic packaging technology. The Overload Relay comes
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
inductive or non-inductive loads at voltages between 200 and 600,
AC.
The fuses have a micro-switch mounted to the body of the fuse that
provides blown/open indication. This switch opens the contactor and
prevents a close operation in the event of a blown/open fuse. This
feature also provides single-phase protection to the motor.
WARNING
MERSEN TYPE AOS-S MICROSWITCHES AND CURRENT LIMITING TYPE
AJT FUSES SIZED AS REQUIRED BY THE APPLICANTION MUST BE USED
TO RETAIN THE IEEE CERTIFICATION. SELECTED FUSE MUST HAVE A LET-
THROUGH LESS THAN SCCR OF CONTACTOR.
