Application Field and Working Principle of 278A11-3

Terminal Blocks - Accessories - Jumpers - 278A11-3 is a pluggable jumper for polarized terminal blocks. It is designed for rated voltage of 50V/AC and a rated current of 8A to 10A, and a working temperature of -50℃ to +85℃. This product has a wide application field in the circuit protection and signal transmission field, such as in domestic and commercial machinery control systems and industrial automation systems. This article will introduce the application field and working principle.

Application Field

278A11-3 pluggable jumpers are widely used in machine tool control, PLC, AC drives, etc. They are used to connect or disconnect electrical circuits quickly and reliably, so they can also be used in any situation where rapid connection or disconnection is required. 278A11-3 pluggable jumpers are made of good quality plastic material and copper contacts, and have good insulation properties and stability. This makes them perfectly suitable for use in all kinds of hazardous environments and heavy duty industrial applications.

278A11-3 pluggable jumpers can also be used for short-circuit protection in various circuits, such as relays, contactors, AC drives, actuators, and more. These jumpers allow you to easily connect or disconnect lines without needing to manually replace the parts. This reduces the risk of making costly mistakes when wiring your system. Additionally, they minimize downtime when setting up and debugging systems.

Working Principle

The working principle of 278A11-3 pluggable jumpers is simple. They consist of two parts which, when connected, complete the electric circuit. When connecting the two parts, the outer shell of the first part is inserted into the other part, and the two pins of the first part are pushed directly into the two holes of the other part - this creates a complete electric circuit. This can be easily accomplished by manually plugging in the jumper or using a special tool.

For permanent connections, 278A11-3 pluggable jumpers are also available with locking options. This locking feature ensures that the electrical connection remains stable even under vibration or shock. When an electrical connection needs to be disconnected, unlocking the jumper is easy with a special tool.

278A11-3 pluggable jumpers are widely used in many control and circuit protection applications, from heavy-duty industrial to light commercial equipment. They offer a wide range of voltage and current capabilities, and the ability to quickly and easily connect/disconnect electrical circuits makes them perfect for many applications. Additionally, their durable construction makes them suitable for hazardous or extreme environments.
