An electrical relay uses a low voltage, low current signal to control an electromagnet. When current passes through the electromagnet, it attracts the spring loaded arm with contactors, which will touch some stationary contactors, closing a circuit on a higher voltage/high current circuit.
An example of this is when your thermostat 'tells' the air conditioner to turn on. The voltage & current from the thermostat are low, while the voltage & current necessary to run the air conditioner's compressor are high..

What is electrical maintenance?
Electrical maintenance is used for maintenance of electrical equipment. Electrical Preventive Maintenance is been used for replacement of Low voltage distribution products such as ACB's & MCCB's Contactors and Relays.
What is an impedance relay?
Impedance relays are used whenever over-current relays do not provide adequate protection. They function even if the short circuit current is relatively low. The speed of operation is independent of current magnitude. Impedance relays monitor the impedance between the relay location and the fault. If the impedance falls within the relay setting, the relay will operate. The basic construction for impedance relays on which the principle of operation is easily explained is the balanced beam.
Where are the fan timer relays located on a 1989 Acura Legend?
Go to your local library and look in the auto electrical books in the reference area. They are cataloged as Japaneese, Acura, 1989, legqend, A/C, coolant system, radiator, auxillary fan operation.
Where are the relays in a 1994 Caprice Classic?
They are all located under the hood in the electrical distribution box.
What are the applications and benefits of using low voltage relays in electrical systems?
Low voltage relays are commonly used in electrical systems for various applications such as controlling circuits, switching devices on and off, and providing protection against overloads. The benefits of using low voltage relays include improved safety, reduced energy consumption, increased efficiency, and enhanced control over the system.
