Disconnectors – main switches for your installation

Disconnectors are a fundamental element of every electrical installation, acting as the main switch. They enable quick and safe disconnection of the circuit, for example, in the event of service work or a failure. Even at the installation planning stage, it's also worth considering electricity meters and surge arresters, which, together with disconnectors, form a complete protection system.

Function and application of disconnectors

A modular disconnector does not actively protect the installation – it does not respond to overloads or short circuits, but allows for a physical interruption of the current flow. This is especially important in emergency situations and during planned maintenance work. In switchboards, disconnectors act as main switches, providing control over the power supply to the entire installation or selected circuits.

Types of available disconnectors

We offer single-, two-, three-, and four-pole disconnectors, adapted to various types of installations – both single-phase and three-phase. These products are designed for DIN rail mounting, making them easy to integrate with other modular devices. It is also worth paying attention to compatibility with differential current circuit breakers with an overcurrent module and nadmiarowoprądowym.

Advantages of using disconnectors

Disconnectors ensure safe and effective separation of electrical circuits, which is crucial for the protection of life and property. They facilitate installation servicing and eliminate the risk of accidental current flow. Their modular design allows for easy installation, expansion, and modification of the electrical system without the need to rebuild the entire switchboard.
