This is also called anti pumping relay. for understanding you have to understand the working of breaker. positive extends to "Low Pressure Lockout" & "Low Pressure Alarm". after maintain the pressure in breaker these NO becomes NC and when breaker closes the auxiliary of breaker get closed and simultaneously extend the positive to the antipumping relay coil by auxiliary contact. by this coil get energised and holding contact get connected and the one of the contact of antipumping coil (NC) become NO which disconnect the command supply of main breaker. by this till when the antipumping relay get energised no further command (+ve) extends to breaker closing coil. This is Antipumping/ Antihunting Relay.
cdg is circular disk gear relay which is electromagnetic relay
A phase sensing relay monitors all three incoming phase legs at once. With the relay the operator has the ability to set the trip points in a percentage of incoming line voltage. If the voltage in any of the monitored legs falls below the operators set point the relay will trip and take the monitored device off line. If it is a motor being protected, the auxiliary contacts on the phase sensing relay will change state and its N.C. contact will open. The motor's contactor coil is in series with this auxiliary contact so with the stoppage of current flow to the magnetic contactor's holding coil, the contactor opens cutting off the supply to the motor.
current relay are using for over current low state & high state.but potential relay are related to voltage.
how the apfc relay work
The ignition relay on a 1995 Jetta is in the fuse box that is up inside the dash on the driver's side of the vehicle. To access this fuse box there are clips holding onto the cover and holding it into the dash.
Location of the Main Relay SwitchThe main relay is located under the drivers side dash panel, behind the fuse panel. There are four Phillips head screws holding the dash panel on and one 10 mm screw holding the main relay in. The main relay is usually marked MITSUBA or something similar and is about 3" X 1.5"
If the fuel system is still holding pressure the car will start and run until the fuel runs out, The relay turns on the fuel pump.
Yes, Under the small bracket holding the connector cable.
To remove the 4G13 main power relay, locate the relay, unplug the wire harness connected to it, unscrew any mounting screws holding it in place, and then carefully lift the relay out of its socket. It's important to disconnect the negative battery terminal first to avoid any electrical mishaps.
The blower motor relay is located behind the glove box compartment beside the blower motor resistor. When you remove the glove box compartment, just look to the left of the resistor and the relay is located directly beside it with a metal retaining frame holding both the resistor and the relay.
Under the hood on firewall beneath brake booster in a bracket holding two relays, the other is the auto shutdown relay. They are purchased and replaced as a pair.
The relay is under the right side dash next to the vent vacuum plunger. Look for wires going into heater box there are two 8 mm bolts holding it in place
Latching current is the minimum amount of current required to maintain the thyristor in on-state immediately after a thyristor is turned on..and Holding current is a minimum current that is required to maintain the thyristor in on-state not allowing it to turn off.Alternative AnswerIf you are referring to a relay or contactor, when the relay is de-energised, there is a break in the magnetic circuit, so the magnetic circuit has an airgap which makes it have a high reluctance. When the relay is energised, the magnetic circuit causes the armature to close, removing the airgap and reducing the value of reluctance. So, when you first energise the relay, there must be a greater magnetomotive to overcome the higher reluctance. When the relay is closed, a lower magnetomotive force will be sufficient to overcome the lower reluctance and maintain the relay closed.
The main fuel pump relay is behind the fuse panel on the drivers side. It has a connector which will need to be unpluged and a screw holding it to a bracket. The new one will go in place of the old one.
The cooling fan relay will be located near the battery mounted on the driver side inner fender. Simply unplug it, remove the 10mm bolt holding it to the fender and reverse the procedure.
there is a multi function relay box mounted on top of radiato under plactic panel it is a box about 4inc by 4inch and has about a 20 wire harness mounted to it with a 5.5 mm bolt holding it in. when you call the dealer just make sure your year has the relay in this box
