KTK-40 devices are magnetic reed switches which are used mainly for motor safety operations and other industrial automation operations. The device utilizes magnetic fields to detect and interrupt current in the circuit. It is usually used in applications where high currents are present, such as hoist or other heavy machinery applications, and is intended for short-circuit protection. It is important to differentiate magnetic reed switches from other types of industrial circuit breakers, as the former utilizes a magnet to detect the presence of a fault current, and the latter relies on a mechanical force to interrupt the current.

The KTK-40 device is composed of three main components: a contact, a housing, and a magnet. The contact, or switch, is a spring-loaded snap-in or screw-in device that can be either open or closed depending on the direction of the current. The housing is typically made of molded plastic or stainless steel, and is designed to protect the internal components from electrical shock and other environmental damage. The magnet is the most essential component of the device, as its field directs the contact to open and close on its own.

When a fault current is detected by the KTK-40 device, the magnetic field of the magnet is directed towards the contact, which causes it to open and interrupt the circuit. When this occurs, the relay is disengaged and no current passes through the device. In order to reset the device after a failure, a manual or an automatic reset must be conducted.

Aside from its use as a fault detection device, the KTK-40, like all reed switches, can also be used as sensing devices in applications such as door and window sensors, end-stops for motion actuators, and anti-tamper switches. In these applications, the contact remains closed until a magnetic field, typically from a permanent magnet, alters its position and causes the contact to open or close.

The KTK-40 is a reliable and versatile device that finds its use in many fields of industrial automation. Its ability to detect and react to magnetic fields makes it ideal for applications where safety and reliability are of utmost importance. The device is relatively easy to install and maintain, and its simple construction ensures a long service life.
