JKSSS+ Series 2.3 - 4.2KV
Chapter 1 - Introduction
This chapter is an introduction to the Toshiba JKSSS+ Series reduced voltage solid
state starter for medium voltage AC motors. It describes the basic conguration,
operation and unit features. It is highly recommended that new users read this
section thoroughly to gain a basic understanding of the starter system before
attempting to start up a unit. If you are already familiar with the JKSSS+ Series
starter, you may begin setup procedures immediately by proceeding to Chapter 2 –
Installation.
1.1 Overview
The standard JKSSS+ Series solid state starter is a complete NEMA Class E-2
motor controller designed for the starting, protection and control of AC medium
voltage motors. It contains the motor disconnect switch, motor circuit fuses,
control power transformer, a line isolation contactor, SCR stack assemblies, a
bypass contactor, low voltage controls and motor terminal blocks in that order.
An optional “soft start only” version is also available which is supplied without
the control power transformer, the disconnect switch and line isolation contactor.
(The soft start only model must be used with a customer supplied, mechanically
interlocked line start panel).

JKSSS+ Series - 4
JKSSS+ Series 2.3 - 4.2KV
1.3 Design Features
The standard JKSSS+ configuration is a complete NEMA Class E-2 motor
controller which includes the following features:
• Isolation Switch:
An isolation switch is provided in the incoming power section of the starter
assembly. The maximum voltage is 7200V.
Power is switched on and off to the controller by a fixed-mounted, externally-
operated, three-pole isolation switch. When the switch is in the opened
position, incoming power is isolated from the controller compartment interior by
an automatic shutter. For additional safety, the load terminals of the switch are
automaticallygroundedwhen the switchisopened. This allowsany stored
energy in the controller load circuit to be discharged by closing the contactor
usingtestpower.
Aviewing windowintheMainIncomingPowerCompartment allowsvisual
inspection of the disconnect blade status with the medium voltage door closed.
The external operating handle for the isolation switch is designed to accept up
to three external padlocks in the OFF position.
Foradditionalinformation on theisolationswitch, seeinstructionmanual
VF010H01,VF010H02 orVF010H03.
•Power Fuses: As a NEMA Class E2 controller, current limiting primary power
fuses are provided for each incoming phase.
Typically the fuses are ANSI class “R” for units rated up to 4800V. The fuses
are sized according to motor locked rotor current and are coordinated with the
solid state overload relay. The fuse and overload coordination is designed to
allow the controller and contactor to clear low and medium level faults. This
prevents exceeding the contactor interrupt ratings. Fuses interrupt high level
faults that exceed the contactor interrupt ratings. Fuse holders include blown
fuse indicators (wired to the isolation contactor circuit) to disconnect all three
phases if any one of the fuses clears (see section 2.7).
• SCR Power Modules: For each phase, the SCRs are
matched devices arranged in inverse parallel pairs and in
series strings as indicated in the chart to facilitate sufficient
PIV ratings for the applied voltage.
• RC Snubber Networks: Provide Transient Voltage Protec-
tion for SCR Power Modules in each phase to reduce dv/dt
damage.
• Firing Circuit: The SCRs are gated (turned on) using a
Sustained Pulse Firing Circuit. This circuitry is amplified and
isolated from the control voltage by means of fiber optics for
current and ring transformers.
