JSC-88 or JSC-88A
Zero-Tolerance Solution
to prevent electric shocks
VOLTAGE DETECTOR
VOLTAGE DETECTOR
208 V - 3 ph. 60Hz 1.9 mA
Made in Canada
When it is time for maintenance and you open the disconnect switch or
breakers, ARE YOU 100% SURE THAT NO VOLTAGE IS PRESENT ?
One of the hazards of today’s plants is working on three-phase
systems. Why is this a hazard ? Because it is difficult to be absolutely
certain that the power is truly « OFF » once the disconnect switch or
breaker has been opened.
HUMAN ERRORS & HAZARDOUS ENVIRONMENTS
Accidents happen … mostly due to human error:
Incorrect measurement setup
Incorrect readings
Lapse of concentration
Accidents also happen due to hazards in the environment:
Carbon deposits (providing electrical path for the current)
Defective voltmeter or accessories
Sticking switch blades
Dual sourcing
Defective electronic breakers which are difficult to diagnose
Any other hazardous situation that allows for conduction after the
breaker or disconnect-switch has been opened
The JSC-88 or JSC-88A helps to prevent accidents
We can now help to prevent electrocutions in the work place, thanks to
the JSC-88 or JSC-88A Voltage Monitor.
The JSC family, thanks to its small size and light socket mounting
design, is easy and quick to install on the door of any starter panel.
Originally developed for Alcan (the well-known International Aluminium
Smelting Company), this voltage monitor has been in large scale use
since 1988 in a number of international industrial environments.
How to use the JSC-88 or JSC-88A … in two easy steps
To use the JSC familly properly, the following steps must be followed
carefully:
STEP #1- While the breakers are still in the « ON » position, make sure
that the three (3) LEDs on the JSC-88 or JSC-88A are « ON » (or lit),
indicating that our voltage detector is working properly and that voltage
is present downstream of the breakers.
Important note : If any of the LEDs is not lit at this stage, an authorized
staff member should investigate the problem and take appropriate
corrective action before proceeding with STEP #1 again.
STEP #2- As soon as the breakers have been switched to the « OFF »
(or Zero Energy) position, examine the JSC-88 or JSC-88A again and
make sure the three(3) LEDs are now « OFF », (i.e. not lit) indicating
that voltage is no longer present downstream of the breakers.
Important note : One or more of the LEDs will remain « ON » if the
JSC-88 or JSC-88A detects any voltage. This would indicate a serious
electrical hazard. An authorized staff member should investigate the
problem and take appropriate corrective action before maintenance
work proceeds.
Note: There is no direct association between a specific led and a given
phase. The JSC-88 or JSC-88A haven’t been conceived for detecting
a phase loss but the presence or not of voltage in industrial
environment.
The JSC-88 or JSC-88A is a very reliable detection unit designed to
indicate visually whether, or not, the voltage on a given system is at
«Zero Energy». It drastically improves the security for maintenance
teams working on three-phase systems. As long as voltage is present
downstream of the breakers, the JSC-88 or JSC-88A LEDs will remain
lit, allowing for a rapid visual inspection for the presence or absence of
hazardous voltages. The use of the optional KLQ-Kit (only with the
JSC-88A) gives an additional security by providing a visual indication
at the motor site.

High-Quality Solution
A full 2-year warranty
UL ( ) and CSA certified
Encased in epoxy, hence 100% resistant to hostile, humid and dusty
environments
High Sensitivity
Can detect and indicate any current leakage greater than 2mA
Easy-to-install

For more informations, see « Specifications »
High Luminescent Visual Indicator
Since the indicators are luminescent (special low-current LEDs),
readings are not affected by ambient light. They can be seen
regardless of their placement on the MCC (motor control center).
Normal Operating voltage
The JSC-88 or JSC-88A comes with a universal voltage reduction kit
that permits operation from 208 volts to 600 volts.
Max. current consumption
1.9 mA
Dimension
72mm X 51mm X 26mm
NEMA-4X
Indoor or outdoor use primarily to provide a degree of protection against
corrosion, windblown dust and rain, splashing water, hose-directed
water, and damage from external ice formation.
IMPORTANT NOTE: Concerning installation of the JSC-88A
For a proper and safe operation, the JSC-88A requires a link to neutral
(or ground where permitted).
On a true floating systems, to use the JSC-88.
