Masterpact™ NT and NW Universal Power Circuit Breakers
Masterpact™ Circuit Breakers

05/2014
Introduction
Masterpact NT/NW Universal 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.
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.
Codes and Standards
Masterpact circuit breakers are manufactured and tested in accordance with the following standards:
NOTE: Throughout this document, the phrase “ANSI
®
Certified” means the product meets the
requirements of UL 1066 and ANSI C37. When “UL
®
Listed” appears, the product meets the requirements
of UL 489.
The 800–2000 A ANSI Low Voltage Power Circuit Breakers type L1F and Insulated Case Circuit
Breaker type LF are tested to show the arc flash hazard risk category as referenced by NFPA
®
70E.
Circuit breakers should be applied according to guidelines detailed in the National Electrical Code
®
(NEC
®
) and other local wiring codes.
Masterpact circuit breakers are available in Square D™ or Schneider Electric™ brands.
