Can you replace an 3 phase solid state relay with a contactor on a 3 phase heater?

Contactor will work on a lower voltage than that of the load, much like a relay. To activate it and close/open the contacts of the 3 phase cct, you need to apply the proper voltage to the coil. Read More

Contactors have both power and auxiliary contacts. We use the auxiliary contact to control magnetic system of contactor. When a heater , relay or a key warn the contactor it is energized and by the typical magnetic interaction it opens its closed power contacts. Read More

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… Read More

A NC contact in a relay will open when the relay is energized. An auxiliary NC contact, in relation to a contactor, will open when the contactor is energized. Read More

One way is to use the auxiliary contacts on the motor contactor to close a separate source supply to drive an auxiliary relay. Read More

A contactor, as far as being used to start a motor or the like, is in essence, a relay. A coil is energized and the normally open contacts from the contactor close (normally 3 contacts for an AC motor) and the motor starts. Do I understand your question? Or are you trying to decifer the difference between the coil of a relay and the contacts of a relay? Read More

The star delta motor starter circuit has to have a control voltage to energize the motor magnetic contractors. A phase failure relay monitors all three phases of the incoming supply lines. The phase failure relay also has auxiliary contacts on it. There are usually two sets of "C" form contacts. The control voltage for the starter circuit must be connected across the normally open (N.O.) contacts of one of these two sets. When the phase… Read More

If you want to control induction motor using a control relay give neutral directly to the one point of coil of relay & one point of coil of contactor then give control supply through push button to second point of coil of relay. use one NO point of relay and give supply to coil of contactor. and also use one NO of contactor for holding the contactor & take OFF (NC) in the starting to… Read More

Shading pole. It helps to stop the relay from chattering. Read More

you would wire a float switch into the control circuit i.e, the contactor coil (which is relatively low current but rated at least for the control voltage,, in most cases 120VAC). also in the same circuit would be the overload contacts. if the overload trips and/or the float switch opens then voltage is removed from the contactor coil Read More

Overloads for motors are sized from the full load amperage that is taken from the motors nameplate. Depending on who the manufacturer of the motor contactor is will govern the sizing of the relay. Some contactors use bolt in heaters and others use a separate unit that connects to the contactor. No matter what method is used make sure to use the manufactures recommended overloads that are based in the motors FLA. Read More

It depends on what your definition of a normal relay is. If it is a small plug in relay to control the motor's contactor then there is no point. All pump motors need control to start and stop the pump. Whether it is done from a pressure switch or a float system it doesn't matter they both should control the motor's contactor and not the pump directly. Most small relays do not have the amp… Read More

A contactor is an electrically controlled switch (relay) used for switching a power circuit. an electro pneumatic contactor is similar to the above except it uses a pneumatic signal to initiate the switching of the electric power circuit. an electro magnetic contactor is a contactor driven by an electric control signal. It us usually just called a contactor. Read More

Yes, when using a three phase contactor on single phase, the three phase overload block can be used. The wiring of the contactor consists of taking L1 of the supply and connecting it to L1 of the contactor. The load is connected to T1 on the bottom of the overload block. L2 of the supply is taken to L2 of the contactor. Instead of connecting the T2 to the load, the conductor is taken back… Read More

There is not a huge difference between C.B. and contactor as they work as a switches but usually CB is normally closed while there a normally open/closed Contactor. the Contactor used only in a control circuit while CB is used on large power system utility, such as substations. Contactor receive an electrical signal from relay while CB need an auxiliary contactor to trip. Most of the CB needs a arc quenching fluid such as oil… Read More

Various components can be added and removed from a contactor. Auxiliary contacts can be inserted in front of the main contacts, as well as a time relay in the case of motor starters (star/delta starter). Usually you should fit a overload relay when you use the contactor in a motor starter, this is inserted in the main contacts at the bottom. However, the internal components like the coil may never be changed or replaced. Read More

the ugly"s book is a good reference.from the contactor /overload relay you need 3 wires and L1 is always your STOP.need a jumper wire which is always the lowest number on your contactor. on a siemens that would be #2. different manufactors have different numbers,your start would be #3 on a siemens contactor or the terminal on the left side of L1. jumper is needed to bring the power to your stop/start. hope this helps… Read More
