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 low-voltage power circuit breakers can also: Enhance coordination by their adjustability Provide integral ground-fault protection 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 NW low-voltage power circuit breakers are manufactured and tested in accordance with the following standards: ANSI ® C37.13, C37.16, C37.17, C37.50 UL ® 1066 NEMA ® SG3 CSA ® TIL Circuit breakers are applied according to guidelines detailed in the National Electrical Code ® (NEC ® ) and other local wiring codes. Features and Benefits High Ampere Interrupting Rating (AIR) MASTERPACT circuit breakers have an interrupting rating of 200,000 A at 508 Vac without fuses. High Short-time Current Rating MASTERPACT circuit breakers have exceptional short-time ratings of 85,000 A in a 3200 A frame and 100,000 A in a 4000 A frame. 100% Rated Circuit Breaker MASTERPACT circuit breakers are designed for continuous operation at 100% of their current rating. True Two-step Stored Energy Mechanism MASTERPACT circuit breakers are operated via a stored-energy mechanism which can be manually or motor charged. The closing time is less than five cycles. Closing and opening operations can be initiated by remote control or by push buttons on the circuit breaker front cover. An O–C–O cycle is possible without recharging. Field-installable Trip Units, Sensor Plugs and Accessories Trip units, sensor plugs and most accessories are field installable with only the aid of a screwdriver and without adjusting the circuit breaker. The uniform design of the circuit breaker line allows these accessories to be common for the whole line. Reinforced Insulation Two insulation barriers separate the front of the circuit breaker from the current path. Tropicalization The standard moisture and fungus protection ensure normal operation under extreme ambient conditions. MASTERPACT circuit breakers comply with T2 tropicalization (IEC Standard 68-2-30); relative humidity 95% at 113°F (45°C) and 80% at 131°F (55°C) hot, humid climate. Salt spray resistance as per IEC 68-2-11.

Reduced Maintenance Under normal operating conditions, the circuit breaker does not require maintenance. If maintenance or inspection is necessary, it is easy to remove the arc chambers and visually inspect the contacts and wear indicator. The operation counter can also indicate when inspections and possible maintenance should be done. It is possible to extend the circuit breaker life by: Replacement of arc chamber and spring-charging motor Replacement of main contacts T TEST 06133337 T TEST 06133338 T TEST 06133339 06133831 06133830 06133832 06133833 Connected Position Test Position Disconnected Position Withdrawn Position 06133185 06133470 Arc Chamber Good Contacts Worn Contacts Wear Indicator Wear Indicator © 1999 Square D All Rights Reserved 6 8/99 MASTERPACT ® NW Low-voltage Power Circuit Breakers MASTERPACT ® Circuit Breakers Front Connection of Secondary Circuits All accessory terminals (ring terminals are available as an option) are located on a connecting block which is accessible from the front in the connected, test and disconnected positions. This is particularly useful for field inspection and modification. Disconnection Through the Front Door The racking handle and racking mechanism are accessible through the front door cutout. Disconnecting the circuit breaker is possible without opening the door and exposing live parts. Isolation Function by Positive Indication of Contact Status The mechanical indicator is truly representative of the status of all the main contacts. Segregated Compartment Once the accessory cover has been removed to provide access to the accessory compartment, the main contacts remain fully isolated. Furthermore, interphase partitioning allows full insulation between each pole even if the accessory cover has been removed. r es e t A pIg I Dn I sd I i Ir Mi c r o l ogi c 70 Reset O OFF discharged 01253 MERLIN GERIN push OFF Ics = 100% Icu 220/440 525 690 100 100 85 Icw 85kA/1s NX 32 H 2 cat.B IEC 947-2 UTE VDE BS CEI UNE AS NEMA EN 60947-2 50/60Hz Ue Icu (V) (kA) volets shutters Test 834 832 831 r es e t A pIg I Dn I sd I i Ir Mi c r o l og i c 70 Reset O OFF discharged 01253 MERLIN GERIN push OFF Ics = 100% Icu 220/440 525 690 100 100 85 Icw 85kA/1s NX 32 H 2 cat.B IEC 947-2 UTE VDE BS CEI UNE AS NEMA EN 60947-2 50/60Hz Ue Icu (V) (kA) volets shutters Test CD3 834 832 831 CD2 06133475 Accessory Terminals Terminal Shield 06133341 Closing and Opening Push Buttons Racking Handle Storage Space Racking Handle Racking Mechanism T TEST 06133339 Disconnected Position 06133832 Door Escutcheon 7 8/99 © 1999 Square D All Rights Reserved MASTERPACT ® NW Low-voltage Power Circuit Breakers MASTERPACT ® Circuit Breakers Circuit Breaker Design Operating Conditions MASTERPACT circuit breakers are suited for use: At ambient temperatures between -22°F (-30°C) and 140°F (60°C) At altitudes ≤ 13,000 ft. (3900 m) MASTERPACT circuit breakers have been tested for operation in industrial atmospheres. It is recommended that the equipment be cooled or heated to the proper operating temperature and kept free of excessive vibration and dust. Operation at temperatures other than 104°F (40°C), may require rerating or overbussing the circuit breaker. See instruction bulletin 48049-106-01 for additional information.
