Magnum Mmk-1 Contactora

MAGNUM MMK-1 Contactor is a large relay, usually used
to switch on/off current to an electric motor or any other high-power
load. Their main purpose is to protect the high-power load (motor/pump)
connected to it from over current damage.

Applications:

Contactors
are used for starting electric motors which are commonly fitted with
overload protection to prevent damage to their loads, and are often used
to provide central control of large lighting installations, such as an
office building or retail building and also used for other electrical
loads.

Contactors are used to control

a) Electric motors
b) Submersible pumps
c) Lighting
d) Heating
e) Air conditioning applications
f) Capacitor banks & other electrical loads.

Salient Features:

• DMC molded coil, specially made to withstand extra heat and perform consistently.
• Exposed metal parts are treated to prevent corrosion.
• There is a provision for taking on an auxiliary contact block with configuration 1NO+1NC or 2NO+2NC.
• Hum-free.
• Easy & quick mounting.
• Encapsulated coil to with-stand wide voltage fluctuations.
• Easily operable and lowest vibrations in its class.
• Silver
  (nickel & cadmium), low bounce designed contacts provide super weld
  resistance characteristics & coated layer in contacts upto 0.3mm
  for best electrical conductivity.
• High electrical endurance - Contacts can perform for more than 1 million operations.

Functions:

• It allows load current switch to turn on or off high current equipments.
• Contactors
  are electromechanical control switches used to control single or multi
  phase power load while the control itself can be low power.
• The main function is to make or break the circuit on receiving a command.
• Can perform millions of operations.
