Contactors (Electromechanical)

KHR500KSANL is a type of contactor from The Schneider Electric company. This type of contactor is used in a wide range of applications and considered to be powerful and reliable. This article will provide an in-depth look into the application field of KHR500KSANL and the working principle behind it.

Applications

KHR500KSANL contactors can be used in a variety of applications due to their mechanical and electrical properties. The contactor can be used in circuits working with high DC voltages up to 500V with a maximum amperage of 150A. It also has a switching capacity of up to 500 kVA. KHR500KSANL contactors are mainly used in power distribution, motor control, lighting control, and UPS systems. It is a great choice for industrial and commercial applications due to its reliability and flexibility. It is also used in heftier applications such as in high voltage capacitor banks or where protection relays are needed.

Working Principle

KHR500KSANL contactors use a unique electromechanical design to enable powerful switching. The contactor consists of an electromagnet which is activated when voltage is applied to it. This electromagnet then attracts an armature which is linked to a set of contacts. When the armature is attracted to the electromagnet, the set of contacts close and power is enabled. When the voltage is removed, the armature moves back to its resting position and the set of contacts open, shutting off power. KHR500KSANL contactor also contains a thermal overload relay which will trip the contactor if the current flow becomes too high, ensuring that the circuits do not become overloaded. This is a great added safety feature which ensures that the contactor is reliably shut off if an unexpected overload occurs.

The KHR500KSANL contactor also comes with a range of unique features which make it particularly suitable for industrial and commercial applications. It is composed of a pre-assembled terminal block which makes installation easy, and the contactor is able to mount on a standard DIN-rail for ease of distribution and has LED indication for an added level of visibility. It also has auxiliary contacts enabling more elaborate control of the circuit and a manual override button enabling manual control of the switch, in case of emergency.

In conclusion, the KHR500KSANL contactor is a powerful, reliable, and versatile contactor. It is suitable for a wide range of applications due to its unique design and features. Its electromechanical design is powerful and secure, and the addition of thermal overload protection ensures that in case of extreme overloads, the contactor is safely shut off. Its range of features also make it suitable for many commercial and industrial applications.
