Switches and switches

Switches and switches are the main components of any electrical system. They are responsible for the correct flow of electricity and the operation of devices, and also allow them to be controlled. For some people, the difference in the nomenclature and the correct classification of these electrical components can be difficult. Their main task is to maintain the continuity of the flow and to turn on and off a certain value of operating currents. They are widely used in the construction of installations in industry and construction.

They are used, inter alia, as main switches for installations, protection of motor operation and operational safety. Switch disconnectors and switches are also installed in switchboards and electrical cabinets of machine control systems. In general, both of these devices are used to manage and maintain a specific cycle of operation of the electrical system components. Disconnectors and switches in the electric circuit protect and ensure continuous operation, according to the rated current value.

Switches and switches in the electric circuit

Depending on the intended use, device function and rated current in the electrical installation, we use the appropriate type of disconnector or switch. Fuse switch and switch disconnector are two basic types of protection that are used in many electrical installations.

Switch disconnectors in the electric circuit

The switch disconnectors include fuse switch disconnectors and switch disconnectors.

Switch disconnectors are often used as the main emergency stop switch. It protects against the effects of overloads and short circuits in the installation. The switch disconnector operates in two modes. Firstly, it isolates the electric circuit and ensures safe operation of the network-connected devices. Secondly, it conducts the current rated value, but only up to the time specified by the parameters.

Fuse switch disconnectors are elements that protect electrical installations in construction and industry. Used for the construction of switchboards in main buildings and production halls. Fuse switch disconnectors perfectly protect installations by switching off in the event of exceeding the upper rated current value and short circuit occurrence.

Switches in the electric circuit

Switches used in installations ensure easy and safe switching and disconnection of power sources in emergency states. Some have the function of forced opening of the contacts. Manual control can be signaled by an LED which informs about the current position of the switch.

Switches can be combined into modules used in control systems. They enable cooperation and control of other building automation products or direct receivers.

Miniature circuit breakers are elements of the electrical installation whose task is to cut off the energy supply when the current exceeds the safe value for a given circuit. The switch is designed to control devices and protect them against the effects of overloads and short-circuits in industrial installations, as well as electric receivers in households. The miniature circuit breakers operate in an alternating cycle on - off.

The residual current device disconnects the devices when a rated surge occurs in the installation. The switch protects the personnel against electric shock in case of direct contact. It also eliminates the risk of fire.
