HIGH AND LOW VOLTAGE CONTROL RELAY<\/h2>\n

\"ConnectHIGH AND LOW VOLTAGE CONTROL RELAY<\/span><\/span><\/h2>\n

Connecting the electrical protection device (phase filler), an important protection device widely used in electrical distribution panels,<\/span><\/span><\/p>\n

Specifically the main power sources, so that the electricity source is disconnected when one of the phases is missing or the voltage value changes from the pre-set values.<\/span><\/span>
\nA very important topic explaining the connection of the electrical protection device (phase wires)<\/span> \/span><\/span><\/span><\/p>\n

, and it may be called by other names, such as: phase sequence relay or a device for protection against phase shortages and voltage changes.<\/span><\/span>
\nWhat is an electrical protection device (phase filler)? <\/span><\/span><\/p>\n

, and even in home electrical panels with the aim of protecting electrical loads.<\/span><\/span>
\nNot only that, but it is also used to protect solar energy inverters from any increase or decrease in the voltage of the electricity network entering it,<\/span><\/span><\/p>\n

 <\/p>\n

\"\"And also from a 3-phase electric Vase falling.<\/span><\/span>
\nElectrical Protection Devices<\/span><\/span>
\nComponents of the Electrical Protection Device (Vase Filler)<\/span><\/span>
\nThe device designated for 1-phase electricity consists of two points (L, N), in addition to three points: (NO, NC, COM).<\/span><\/span>
\nThe device designated for 3-phase electricity contains three points: (L1). ,L2,L3,N)<\/span><\/span><\/p>\n

 <\/p>\n

, in addition to the relay contact points: (NO, NC, COM).<\/span><\/span>
\nConnecting the electrical protection device (1 phase)<\/span><\/span>
\nConnect the electricity source to Connect two terminals (A1, A2) while ensuring the type of supply and the appropriate voltage.<\/span><\/span>
\nConnect the open contact point NO in series with one of the terminals of the contactor coil or relay A1.<\/span><\/span>
\nConnect the contact point NO The common contact COM with the supply line depends on the voltage value and the type of contactor coil current.<\/span><\/span>
\nConnect the remaining contactor terminal or relay A2 with the supply line.<\/span><\/span>
\nConnecting the 1 phase protection device <\/span><\/span>
\nBuilt-in protection device against phase shortages and voltage changes 1 phase<\/span><\/span>
\nConnecting the electrical protection device (3 phase)<\/span><\/span>
\nConnecting the 3 phase power supply With the three points (L1, L2, L3, N) in order.<\/span><\/span>
\nConnect a line from L1 to the common point COM.<\/span><\/span>
\nConnect the open point NO with the contactor coil terminal K <\/span><\/span>
\nConnect the other end of the contactor A2 with the neutral line of the electricity source.<\/span><\/span>
\nConnect the power circuit of the motor by connecting the ends of the electricity source to the contactor points.<\/span><\/span><\/p>\n

The main and output points with the terminals of the electrical load, such as the electric motor, for example.<\/span><\/span>
\nConnecting the electrical protection device (phase filler)<\/span><\/span><\/p>\n

\"\"<\/p>\n

What is required to protect the motor from falling phases or increases and decreases in the source voltage?<\/span><\/span>
\nFirst:<\/span><\/span><\/p>\n

Purchase a protective device that has the following protections:<\/span><\/span><\/p>\n

(Protection against voltage shortages and voltage changes).<\/span><\/span>
\nSecond:<\/span><\/span><\/p>\n

Buy a good quality contactor from a famous brand, such as:<\/span><\/span><\/p>\n

ABB or any other brand, and choose it so that its current is at least 25% higher than the motor current.<\/span><\/span><\/p>\n

Also make sure that the coil voltage and the type of current it operates on are compatible with your requirements.<\/span><\/span>
\nAppropriate contactor = load current x safety factor ratio<\/span><\/span>
\n= 27 x 1.25 = 33.75 amps<\/span><\/span>
\nYou can buy a contactor with a capacity of 40 amps.<\/span><\/span>
\nThird:<\/span><\/span><\/p>\n

Finally, connect the electrical protection device (phase filler)<\/span><\/span><\/p>\n

With the contactor as shown in the diagram above in order to connect and disconnect the current from the electric motor based on the condition of the device.<\/span><\/span><\/p>\n
