Increase the reliability of your electrical distribution system
Through the years bolted pressure contact switches have been installed as the
main disconnect for facilities all over the country and most facility personnel never
give them a second thought. A bolted pressure switch can typically be identified
by its long operating handle that compresses the operating mechanism spring.
Periodic maintenance, cleaning and lubrication of a bolted pressure contact
switch is required to provide reliable operation. Failure to properly maintain
this switch could result in costly downtime, especially if it serves as the main
disconnect for your entire facility. Schneider Electric Services provides a range
of services designed to extend the life of your bolted pressure contact switch
and increase the reliability of your electrical distribution system. Based upon
your specific needs or preferences, we offer:
• Preventive maintenance for your existing switch
• Replacement and upgrade of your existing switch with a Square D
Type B-L Bolt-Loc switch
• A retrofill solution with the Square D Masterpact NW circuit breaker

Preventive maintenance solutions
Experienced Schneider Electric Services technicians
perform a comprehensive scope of work, based
upon manufacturers’ specifications for all
rated switches.
Preventive maintenance, including visual inspection
and exercising the operating mechanism, should be
performed at a minimum of once a year. Thorough
cleaning and lubrication should occur every three
to five years, depending upon the amount of usage
and ambient conditions. Molybdenum disulfide
grease is recommended for the Square D Bolt-Loc
switch; refer to the Square D Services Lubrication
Manual (Catalog #0100DB0802) for other
manufacturers’ recommendations.

Retrofill solution
Schneider Electric Services offers a retrofill solution
that reconfigures the switch compartment to accept
a new Masterpact NW circuit breaker. Utilizing
the existing structure represents an economical
alternative to purchasing new equipment.
Using the upgraded technology of our Masterpact
NW insulated case circuit breaker, a retrofill solution
provides solid state protection and reduces
maintenance requirements. In fact, under normal
operating conditions, Masterpact circuit breakers
require minimal maintenance.
A Square D Masterpact NW low-voltage circuit
breaker is retrofilled into the switch compartment of
the old bolted pressure switch. The retrofill solution
includes the associated draw-out mechanism,
doors, wiring, metering, bus connectors, fasteners,
and hinges.
Masterpact circuit breakers can also:
• Enhance coordination by their adjustability
• Provide integral ground-fault protection
for equipment
• Provide high interrupting ratings and
withstand ratings
• Provide communications
• Provide power monitoring
• Provide protective relaying functions
• Provide zone-selective interlocking (ZSI) which
can reduce damage in the event of a fault
In addition, Schneider Electric Services
provides on-site services, equipment testing
and project management.
Masterpact NW power circuit breakers are designed
to protect electrical systems from damage caused by
overloads, short circuits, and equipment ground faults.
All Masterpact circuit breakers are designed to open and
close a circuit manually, and to open the circuit automatically
at a predetermined overcurrent setting.
