Power relays represent a reliable method for providing high current switching capabilities for a large network. A power relay, also known as a switching relay, is an electrical component that is used to control a high current circuit, such as electric motors and other industrial applications. They are used to switch high currents (over 2 amperes) quickly and with low losses, ensuring that a regulated current is not disrupted by a mechanical fault. KRPAs, are a type of power relay, specifically designed for switch applications. The KRPAs 11DN-12 is a particularly powerful and reliable model.

The KRPAs 11DN-12 power relay has a very wide range of applications in low voltage and high current industrial control circuits. They are typically used to switch medium to high loads of current, from 2 to 30 Amps. It is typically used in drive systems, motor and power control circuits, industrial automation, and general purpose control applications. The 11DN-12 has a maximum current of 30 Amps and can be used in DC circuits up to 600V. It is designed with a highly reliable contact-sealed structure with minimal power loss.

The KRPAs 11DN-12 power relay is designed with a silent operation. It features a small contact gap, which ensures minimum arcing and noise. This design also prevents weld damage and maximizes working life. It also features a short-time operating function, which allows it to be used as a safety or protection device, ensuring that electric shock does not occur in the event of a mechanical fault or overload.

The working principle of the 11DN-12 power relay is quite simple. The relay has an input terminal, which is connected to an electric power source and the output terminal which connects to the electric loads. An electromagnetic coil is used to convert electric energy into mechanical energy, and this mechanical energy is used to open and close the contacts in the relay. When current is supplied through the input terminal, the coil creates electromagnetic current which generates mechanical force to open or close the contact points.

The 11DN-12 power relay can be used in a variety of applications including motor control circuits, drive systems, industrial automation, and general purpose control. Its silent operation, low power loss, and reliable contact-sealed design make it an ideal choice for many industrial and commercial applications. It is also suitable for applications that require maximum current without the risk of short-circuiting due to mechanical failure.
