Switch disconnectors

Switch disconnectors are the basic types of protection that are used in many electrical installations. First of all, they protect against short circuits and overloads that occur during a failure of the electrical system in a given facility. This allows you to protect devices and equipment connected to the electrical system. The disconnectors are used as main emergency stop switches.

Switch disconnectors:

characteristics

Switch disconnectors are devices whose main task is to isolate an electric circuit . Using them prevents the failure of the entire installation. All these types of devices work in two ways. Firstly, they conduct the current under rated conditions and, secondly, they isolate the circuit, ensuring safe operation of all machines and devices connected to the network. Each time it is important to remember that when choosing disconnectors from specific manufacturers, such as Kanlux or Hager , you should match them to the specific installation in which they are to operate. The number of poles is analyzed for the selection of switch disconnectors. Therefore, there are 1- and 2-pole disconnectors as well as 3- and 4-pole disconnectors.

1-pole disconnectors are designed to cut off the power supply in a selected section of a given installation. They are used in single-phase networks. Their symbol is 1P.

2-pole disconnectors guarantee complete cut-off in single-phase electrical installations. They have the symbol 2P.

3-pole disconnectors are commonly used. Their sign is 3P. They guarantee cutting off the current in selected sections of three-phase electrical installations. They are versatile.

4-pole disconnectors ensure complete cut-off of electricity from the electrical installation, cooperating with three-phase installations. This type of disconnectors is used to protect the home electrical installation. They should be used where there is a higher risk of failure.

Switch disconnectors: select

Switch disconnectors perfectly eliminate the effects of short circuits and overvoltages . They guarantee effective insulation of the electric circuit. When facing the choice of a specific device in this range, you should follow the manufacturer who made it. It can be Kanlux or Hager, because their products have great parameters. Of course, the type of disconnector is also important. You need to know if you want to buy a 1- and 2-pole disconnector or other. The main parameters to consider include:

  1. rated current,
  2. supported rated short-time current withheld,
  3. supported short-circuit making current,
  4. short-circuit withstand,
  5. international standard adequate for a specific device,
  6. abrasion resistance,
  7. build depth,
  8. presence of an indicator light,
  9. number of poles,
  10. degree of protection.

Models of individual switch disconnectors determine how a particular apparatus will work. This eliminates the effects of short circuits and overvoltages, which is of great importance for the operation of the entire electrical installation.

The R fuse switch disconnector is used in three-phase networks. Its task is to protect individual devices and provide them with the appropriate dose of electricity. This type of device is therefore not only switch disconnectors, but also main disconnectors. Additionally, this type of disconnectors can be used to operate and protect electric motors.

The FR switch disconnector is available in several types, mating with the rated current in the range from 20 to 125 A. This type has several poles and can be combined with a special signaling of the closing state.

The RBK switch disconnector is used in cable cabinets, switchboards and distribution boards.

Switch disconnector with a trigger is a modern device, the operation of which is determined by the release.

The switch disconnector with a visible contact gap allows you to observe the state of the apparatus contacts.
