3KF switch disconnectors with fuses protect against overload and short-circuits as main control and ENERGENCY-STOP switches of switchboard assemblies, power distribution boards, power supply and motor outgoing feeders.

In conjunction with SITOR semiconductor fuses, they are also used in UPS systems, frequency converters and capacitor control systems.

3KF switch disconnectors with fuses are designed to switch the specific rated current on and off under load. At the same time, they constitute a safety isolating function and isolating distance in all low-voltage circuits.

All 3KF switch disconnectors with fuses are climate-proof and meet the requirements of IEC 60947-1, IEC 60947-3 and VDE 0660-107.

Functionality

Despite the ongoing and consistent development of the functionality, ease of operation for programmers and users has always been paramount. For this reason we introduced “ready-to-use functions” such as ON/OFF delay, weekly timer, pulse generator, astro timer, annual timer, stop watch, etc. which usually have to be programmed first in a typical PLC. More than 40 functions are available and programs can include up to 400 blocks.
