Contactors (Electromechanical) are devices used to switches electrical circuits. They are typically controlled by a system and can provide protection to both the power circuit and the control circuit. The CC50/4SA120 contactor is a two-pole four-pole contactor mainly used in single-phase and three-phase power distribution purposes. This type of contactor is a heavy-duty contactor with an auxiliary contact. The contactor is designed to be a reliable and durable unit, capable of withstanding the tough loads associated with switching inductive and resistive loads.

The contactor’s design and construction makes it very suitable for high current applications and able to provide surge suppression on power supply lines. The contactor has a wide range of operating voltage, from 500V to 690V. The contactor is also designed to have a high switching current capacity up to 4SA120A.

The operation of the contactor is based on the contact forces between the contact and the coil. The contactor is connected to a coil which is normally energized when it is to be actuated. The coil consists of an electromagnet that when energized produces a magnetic field which attracts the armature pushing the contacts. The contact-closing force is greater than the normal contact-opening force. When the coil is switched off or de-energized the normal contact-opening force takes over. The contactor will switch open.

The contactor is also equipped with a voltage surge suppression feature that helps in protecting electrical equipment by providing additional break time when there is a large voltage transient. The contactor is also provided with a wide range of auxiliary contact options that can be used for various functions. This includes normally closed contacts, normally open contacts, and change-over contacts.

The CC50/4SA120 contactor is not only high in quality but also cost effective. It is designed to provide a reliable, efficient, and safe operation for power distribution systems. It is suitable for applications in transformer, breaker, plug-in, and machine tools, as well as in industrial automation systems, industrial vehicles, electrical equipment in hazardous surroundings, and more. The use of this contactor ensures a long service life and cost savings.
