3 With such high standards, our range of circuit breakersare able to meet your highest demands for quality, safety and reliability. 7 SIRIM QAS certificationf e a t u r e8 SIRIM QAS certification9 SIRIM QAS certificationf e a t u r e10 SASO certificationICS = ICU 100%11NF series circuit breakersThe demand for economical and high performance circuitbreakers is ever increasing in the global market. The NFseries circuit breakers provide a simple and reliablesolution to meet this global demand where quality,performance and compliance are NF series circuit breakers have been engineered to provide effective protection to low voltage powerdistribution systems. The NF series is a complete rangeof MCCB s from 10A to 1200A with 1, 2, 3 and 4 poleversions.

4 An extensive range of electrical accessories isalso repulsion breaking methodThe double repulsion method uses a reverse-loop of current (I) flowing inessentially opposite directions (see figure).This creates a repulsion action and results in a greater opening force (Fm) betweenthe fixed and moving contacts. This forcealso assists to rapidly extinguish the arc,thereby causing the moving contacts toopen faster. A faster breaking time isachieved with this contactsfixed contactf e a t u r e12double number of contact coppersFor the NF600 and above circuit breakers,double moving contacts are used instead of a single contact. This additional movingcontact improves the short circuit breakingperformance and reduces contact of the NF seriesThe design of the NF series circuit breakers makes itsuitable to be used in hot and humid climates.

5 Thematerial used for the circuit breaker casingconsists of synthetic resins reinforced withglass fibers. Furthermore, the metal partsused in the breakers are chemically treatedto protect against corrosion. The externalcopper terminals are tin-plated to moving contacts in NF120013method of installationThe NF series circuit breakerscan be installed in vertical orhorizontal position without anyimpact on its performance orde-rating of cross sectional areapositive indication & operationhorizontalverticalThe circuit breaker operating handle is designed to indicate the exact position ofits moving contacts. Its trip-free operating mechanism cannot indicate that thebreaker is ONif the moving contacts are in the OFFposition.

6 If the breaker tripsdue to an electrical fault or overload the handle will be in between the ONandOFFposition. This is the TRIP position. To switch the breaker ONafter tripping,the handle position must be switched to OFFposition first and so to reset thebreaker and then switch to the Index for cross-sectional area of MCCBA MCCB casing made of high-impact BMC material reinforced withglass fibres, providing a safe and strong housing in the event ofbreaking high-fault Trip-free mechanism ensuring positive operation and isolationsuitability. Designed for long service life and high number ofoperating cycles.
