Circuit breakers

For circuit breakers, consider series, pole version and electrical parameters together. Determine the appropriate device for the specific circuit; general size or a similar designation is insufficient for replacement.

Retain the series in the comparison

The category includes Acti9, TX, DX, RX, S and SH ranges, as well as other versions. Do not reduce the choice to a single current value. The full code identifies the specific version being compared and allows matching data and accessories to be found. When adding to an existing distribution board, also record the series of equipment already used.

For the Acti9 iC60N family, thermal overload tripping and magnetic short-circuit tripping are described. This is a characteristic of the stated family, not grounds to treat every product in the category as identical. Compare different series by their own documentation and the specific application's requirements.

The curve and electrical fields have different roles

With iC60N, curves B, C and D are different magnetic tripping variants, rather than quality levels. Choosing between them is not simply a preference for a higher letter; load data, starting conditions and the design are required. Do not transfer a choice for one circuit to another solely because the devices have similar names.

Pole count, rated current and breaking capacity are separate fields in iC60N. tables. Compare them separately alongside voltage and the specific version. Rated current does not replace breaking capacity. Also check AC and DC designations for the exact device instead of treating them as common to the whole series.

Check the configuration around the device

Clarify the mounting width and required accessories, especially when replacing part of an existing configuration. Physical positioning in the row alone does not prove compatibility with a comb busbar, auxiliary contact or remote control. For the manufacturer ranges, you can continue to SCHNEIDER ELECTRIC and ABB, retaining the exact series in the search.

If the task concerns another component type, browse load-break switches and disconnectors. The general circuit breakers and fuses category helps distinguish the areas. For final selection, have the full device designation and circuit data to hand; selection and replacement must be checked for the specific equipment, without instructions for mains-voltage wiring.
