Power disconnectors and isolators

If a facility requires manual switching on or de-energizing of a section of the electrical network, a power switch or disconnector is essential. This section features power switching devices for industrial workshops, distribution panels, and boiler rooms, including the TeSys range from Schneider Electric. You can find models for different rated currents, protection ratings, and mounting methods — from compact panel-mounted versions to heavy-duty industrial units. Every product is checked for compliance with applicable standards, so you can purchase the equipment with confidence in its quality.

What This Equipment Is and Who It Is Suitable For

A power switch is a mechanical switch for a power circuit: simple, reliable, and without electronics that could fail at a critical moment. A disconnector performs a similar function, but it is primarily installed to provide a visible circuit break before maintenance or repairs — this is a matter of safety, not just convenience.

Who may need this equipment:

• electrical installers assembling distribution panels;
• production engineers who require manual backup disconnection;
• facilities where safety regulations require an emergency switch near a machine or production line;
• service teams responsible for maintaining industrial equipment.

In practice, front-operated models are often preferred — the handle is mounted on the cabinet panel, so the operator does not need to open the door while the equipment is energized.

How to Choose the Rated Current and Design

There is an important point here: a mistake at this stage can cost more than the device itself. Choose the rated current based on the load current with a 20–25% safety margin, and also consider the protection rating and number of poles.

Parameter | Residential Use | Industrial Use
Rated current | up to 100A | from 100A to 1600A
Protection rating | IP20-IP44 | IP54-IP65
Number of poles | 1-3 | 3-4

If you are unsure about the calculations, it is better to order a consultation with our specialists right away than to modify the distribution panel later.
