The contactor is an electrical device which is used for switching on and off electrical circuits. They open and provide operating power to the load when the contactor coil is energized.
Contactors are used for controlling electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads.

When is a contractor most useful
Contactors are generally used for circuit manipulation and are most common in industrial circumstances. Due to their contact-less transition from 0 to 1, they are considered quite a safe method of empowering an electrical network.
Their use allows for the control and switching between low voltage, sensitive electronics like computers, and between high intensity machinery. Controllers are the main part which allows the communication between, and mitigation of, voltage difference between two different circuits, making it possible for small electronics like a computer chip, to control high powered industrial equipment.
They can be used in series or as a single unit allowing users to interact with multiple circuits at once. They could be on a timer, utilizing our Time Delay Contact Block LT02-DXX, which means it can be programmed to open or close a circuit at a specific time, which is used for non-personnel operations or for a scheduled shut down for maintenance or other work related to the electrical system.
What contractor types do we have
In our portfolio are included low voltage contactors 6A-95A, contractors 115A-800A, Auxiliary contact blocks and Module contactors LM-K series which are separated in two main directions: Alternating current and Direct current. Their coil voltage ranges from 12V to 400V.
Low voltage AC contactors
The LT1-F series
This is a series of contactors for AC which can be used for the consumption of electrical energy ranging from 115A up to 800A. It’s functions are quite usual for the series of contactors and maintain high functionality within those parameters. The LT1-F can be attached with the use of flexible electrical wires making it one of the easiest to install units.
CJ19-43 is a low voltage for switching on and off capacitor banks. It’s specially designed for the commutation of three-phase capacitors which are used for the correction of voltage in systems. These contactors are most suitable for systems and batteries of up to 50 kVAr.
Its best use is for the control (on and off) of capacitor batteries used for the compensation for reactive power. This is a unit with AC coil and is rated for use with 32 A up to 170 A nominal electrical charges.
Low voltage DC contactors
LP1-D is used for the control of AC consumers and is equipped with a DC coil. There are most often used for high frequency of on-off cycle systems and have an enclosed case suitable for dirty working environments. There are LP1-D models which vary in nominal electric charge capacity, from 9 A up to 225 A.
There are also auxiliary units which can be added on to existing installations, long distance controller and contactors and even timers which allow you to set an exact time for an on-off cycle.
