Load-break switches and disconnectors

Load-break switches and disconnectors are compared by intended use, version and specific package contents. Separate the device itself from the handle, housing and accessories that may form part of its solution.

Specify which component you need

The category includes load-break, rotary and different disconnecting versions, including fuse products. Keep the full device name and series when searching. Do not choose solely by external handle: similar control methods do not describe every function or compatible accessory of different devices.

Check whether the listing has a handle, lacks a handle or comes in an enclosure. Also clarify control positions by exact reference. A switch, door kit and finished enclosed device are different comparison items. A shown accessory should not automatically be considered included if the stated contents do not list it. For through-door control, clarify the intended components instead of assuming every handle from a similar series will fit.

Poles, electrical data and dimensions

The range distinguishes pole versions, current and voltage designations and models with DIN mounting. Match each criterion to the required configuration. Pole designation is not mounting width, and stated current does not replace the application's other requirements. Final selection requires the specific device's data, not just its general family.

For a fuse version, clarify the matching format and which parts are supplied. Browse the fuse links themselves in fuses. The size of the fuse link and the external size of an enclosure are different information and should not be confused when comparing items.

Assess the housing separately

If the selected solution is enclosed, examine the enclosure's own data and conditions of use. In an IP designation, the first digit concerns solid objects and dust, while the second concerns water. IP does not automatically describe resistance to chemicals, UV or mechanical impact. Impact resistance has a separate IK designation; a higher IP does not prove a higher IK.

To distinguish these from protective equipment, continue to circuit breakers. The general circuit breakers and fuses section helps organise the different tasks. Prepare a list with the device, control, housing and accessories so that compatibility between the exact components can be checked without assuming shared functionality across the entire category.
