SCN-2660SC is a reliable and mature open-coil contactor, which is widely used in DC applications. It is a highly reliable and compact contactor, designed for continuous switching. The contactor has a long life of 100,000 cycles at 200V DC, 1,500 cycles at 400V DC and 5,000 cycles at 28V DC.

The contactor is used for the DC circuit and the application field of SCN-2660SC includes electromechanical devices, electric furnace, fire control, refrigeration, lighting, lift, air conditioning, power distribution, radio/TV, electronic circuits, motor control, various distributed switching and local/switchboard protection.

The contactor works on the principle of electromagnetism. It consists of an electromagnetic coil which develops a magnetic field when connected to a current source. The presence of this field attracts a movable armature that holds the contacts of the contactor. When a current is sent through the contactor, the armature is drawn into the electromagnetic field, making contact with the upper and lower contact points of the contactor. As soon as the current is taken away, the magnetic field generated by the coil collapses and the armature is released, thereby re-establishing the open circuit.

The contactor has a wide range of applications due to its many features. It has superior electrical and thermal properties and it is insensitive to dust, dirt, vibration, and shock. It is also capable of switching DC under high current conditions, allowing for quick switching through the control circuit.

The SCN-2660SC is easy to install and maintain and can be used in a variety of different applications. It is a reliable and durable contactor which makes it a suitable choice for any DC circuit. Its operating principle is clear and easy to understand and suits the requirements of most applications. Its robust construction ensures a long life of trouble free operation.
