Operating mechanism type EL

The low speed of the contacts, the short running time and the low mass limit the energy required for operation and thus ensure extremely limited wear of the system. Circuit breakers

therefore require only limited maintenance.

VD4 circuit breakers have a mechanical operating mechanism with energy storage and free tripping. These features make opening and closing operations independent of the operator.

The operating mechanism is very simple to conceive and use, can be customised with various accessories and is quick and easy to install. This simplicity makes the equipment more reliable.

Structure

The operating mechanism and the magnetic poles are fixed to a metal frame which also serves as a support for the fixed circuit breakers.

The compact construction ensures robustness and mechanical reliability.

The tractable circuit breakers are also equipped with a bracket trolley for putting them into or taking them out of the switchgear or enclosure with the door closed.
