Changeover Switch-Disconnectors: Telergon Solutions from 63 A to 3150 A

Changeover switch-disconnectors are essential components in numerous electrical installations. They allow switching between different circuits or power sources and provide the necessary isolation functions.

Telergon offers different series of on-load changeover switch-disconnectors. They are designed to meet different current ratings, installation space and automation requirements. The CEC, CCF and S5F series cover a range from 63 A to 3150 A, with 3P and 3P+N versions and different operating options.

CEC Series: Compact solution from 63 A to 125 A

The CEC series comprises compact on-load changeover switch-disconnectors from 63 A to 125 A, available in 3P and 3P+N versions.

Its compact design reduces the space required for installation, while its internally bridged common output eliminates the need for external bridges. It also offers different mounting options thanks to its movable mounting feet and modular design.

The 3P+N versions feature advanced neutral connection and delayed neutral disconnection. This provides protection against accidental overvoltages in equipment connected between phase and neutral.

CCF Series: up to 1250 A with motorised operation

The CCF series offers on-load changeover switch-disconnectors for higher-current applications, with solutions up to 1250 A and 3P and 3P+N versions.

Its compact design combines a long electrical and mechanical life with reliable operation in industrial environments and demanding environmental conditions, including tropical and polar conditions.

The CCF series can incorporate motorised operation in sizes 1, 2 and 3, from 200 A to 1250 A. The motorised unit is supplied as a separate kit, making installation and replacement straightforward.

S5F Series: high-current switching up to 3150 A

The S5F series is designed for applications requiring higher switching capacities, with solutions from 125 A to 3150 A in 3P and 3P+N versions.

These changeover switch-disconnectors offer a long electrical and mechanical life, even in industrial environments and demanding environmental conditions. The 3P+N versions feature advanced neutral connection and delayed neutral disconnection.

The S5F series can also incorporate motorised operation in selected sizes. From 125 A to 200 A and from 1600 A to 3150 A, using a separate kit that is easy to install or replace.

Manual and motorised operation

The type of operation is an important consideration when selecting a changeover switch-disconnector.

Manual operation allows the device to be operated directly using its handle. When the installation requires automation or remote control, motorised operation allows the switching function to be integrated into control systems and enables certain operations to be carried out without direct manual intervention.

This option is particularly relevant in installations where operations need to be automated, the management of different power sources needs to be facilitated or the system’s response capability needs to be improved.

A range adapted to each application

The CEC, CCF and S5F series allow a solution to be selected according to the required current rating, available space, pole configuration and level of automation of the installation.

From the compact design of the CEC, through the versatility of the CCF, to the high-current applications of the S5F, Telergon offers switching and isolation solutions for different electrical requirements.
