NF series circuit breakers

The demand for economical and high performance circuit

breakers is ever increasing in the global market. The NF

series circuit breakers provide a simple and reliable

solution to meet this global demand where quality,

performance and compliance are required.

The NF series circuit breakers have been engineeredto provide effective protection to low voltage power

distribution systems. The NF series is a complete range

of MCCBs from 10A to 1200A with 1, 2, 3 and 4 pole

versions. An extensive range of electrical accessories is

also available.

double repulsion breaking method

The double repulsion method uses areverse-loop of current (I) flowing in

essentially opposite directions (see figure).

This creates a repulsion action and results

in a greater opening force (Fm) between

the fixed and moving contacts. This force

also assists to rapidly extinguish the arc,

thereby causing the moving contacts to

open faster. A faster breaking time is

achieved with this design.

double number of contact coppers

For the NF600 and above circuit breakers,

double moving contacts are used instead

of a single contact. This additional moving

contact improves the short circuit breaking

performance and reduces contact wear.

materials of the NF series

8

The design of the NF series circuit breakers makes itsuitable to be used in hot and humid climates. The

material used for the circuit breaker casing

consists of synthetic resins reinforced with

glass fibers. Furthermore, the metal parts

used in the breakers are chemically treated

to protect against corrosion. The external

copper terminals are tin-plated to prevent

oxidation.

method of installation

The NF series circuit breakers

can be installed in vertical or

horizontal position without any

impact on its performance or

de-rating of characteristics.

MCCB cross sectional area

positive indication & operation

9

horizontal vertical

The circuit breaker operating handle is designed to indicate the exact position of

its moving contacts. Its trip-free operating mechanism cannot indicate that the

breaker is ON if the moving contacts are in the OFF position. If the breaker trips

due to an electrical fault or overload the handle will be in between the ON and

OFF position. This is the TRIP position. To switch the breaker ON after tripping,

the handle position must be switched toOFF

position first and so to reset thebreaker and then switch to the ON position.

A MCCB casing made of high-impact BMC material reinforced with

glass fibres, providing a safe and strong housing in the event of

breaking high-fault currents.

B Trip-free mechanism ensuring positive operation and isolation

suitability. Designed for long service life and high number of

operating cycles. Metal parts in mechanism are chemically treated to

withstand harsh tropical weather conditions.C Arc chutes with predefined steel plates arrangement, provide high

breaking capabilities.

D Fixed and moving contacts utilizing the reverse loop current

method, creates a repulsion force thus rapidly extinguishing the arc.

E Common trip mechanism to ensure breaking of all poles even when

the fault occurs at a particular pole.

F Trip release consists of thermal (bi-metal) and magnetic devices

suitable for use in AC or DC supply voltages.

suitability for isolation

In compliance with IEC 60947-2 standard, NF series

circuit breaker guarantees no leakage currents and over-

voltage withstand between the supply and load terminals

when its moving contacts are in the open position.

compliance with standards

The NF series circuit breakers have been designedto meet international standards, complying with the

following standards:

1. IEC 60947-2: International Electro Committee

Standard

2. BSEN 60947-2: British Standard European Norm

3. JIS C 8201-2: Japan Industrial Standard

phase insulation barriers

Inter phase barriers are provided as standard. The use

of the inter phase barriers is

necessary to increase the

clearance distances between

phases to prevent electrical

faults during the operation

of the circuit breaker.

electrical accessories & shunt trip

All electrical accessories supplied for the breaker are pre-

wired. Accessories such as Shunt Trip, Under Voltage Trip,

Alarm Switch, Auxiliary Switch and combination Alarm and

Auxiliary Switch can be fitted into the breaker accessory

compartments. Please refer to the table in page 31 for the

accessories installation guide.

Shunt Trip Device

The Shunt Trip device opens the circuit breaker by means

of an electrical signal. Voltages between 70% and 110% of

the coil voltage rating will operate the shunt trip device.

All Shunt Trip devices are factory fitted with a cut-off

supply switch.30

under voltage trip device

31

The Under Voltage Trip device will open the circuit breaker contacts when the supply

voltage to the coil drops below 70% of its voltage rating.

After tripping, the circuit breaker can be closed manually

again when the supply voltage is 85% of its coil voltage

rating or more.

The Under Voltage Trip device is always energized duringnormal conditions when supply voltage is healthy.

signaling switches

The Signaling switches allow the breaker

status information to be obtained remotely.

The signaling switch consists of several dry

contacts with both normally open (N.O.) and

normally closed (N.C.) positions.

Auxiliary Switch - Provides breaker ON and

OFF status information.

Alarm Switch - Provides breaker TRIP status

information.

Auxiliary + Alarm Switch - Provides breaker

ON, OFF and TRIP status information.

rotary handle | mechanism

32

M C C B


The breaker mounted rotary handle mechanism allows the user to easily switch thebreaker ON by a rotating action.

The rotary handle mechanism is equipped with a safety device that prevents the

panel door from being open when the breaker is in ON position. A bypass screw is

provided for manual intervention when breaker is in ON position.

Pad locking facility is available on the rotary handle. The handle can be pad locked

when the breaker is in OFF position.

Please refer to the above

circuit diagram for the switch

terminal codes in order to

obtain different contact

positions, such as N.O. and

N.C. to suit the application.

A direct rotating operating handle has a standard safety device which prevents the

breaker from closing as long as the cover is open. It indicates the tripping of the

breaker even in ON-lock position, but only in cases when a single padlock (35mm)

is used. The degree of protection, in accordance with IEC529, is IP3X (or IP5X with

provision of dustproof packing).

The use of the

rotary handle

mechanism

increases the IP

rating of the breaker

The figure above shows the relationship

between the hinge and breaker viewed

Notes

1) It is NOT possible to install both UVT and STC in the same MCCB.

2) For NF600 onwards, it is possible to install up to a maximum of 4 Auxiliary. Switches or 2 Alarm switches.

3) UVT requires a voltage module that is installed on the right side lead wire terminal.

Short Circuit protection of electric motors

The NF series circuit breakers are suitable to combine with motor starters. As defined in IEC 60947-4

standards, the starter switching device, usually a magnetic contactor, must be coordinated with the

equipment capable of providing short circuit protection for circuit wiring/cables.

The common starting methods for asynchronous squirrel-cage induction motors which the NF series can be

used in combination are the direct-online-starters and star-delta-starters.

The following selection tables, illustrating the above, shows the suitable breaker ratings that can

accommodate motor starting currents. When more than one motor is connected to a branch circuit, the

sum of the motor rated current equals to the rated current of the breaker.

Please note that the breaker selection shown in the tables are subjected to the following: only 1 motor to be installed in the circuit and

the starting current is less than 6 times of motor full load current.

tightening range* Nm Bolt/Screw

To ensure the correct operation of the MCCB, it is essential to make a proper

cable or busbar termination to the MCCB. It is recommended that the
