Switch - disconnectors VRE are designed for manual switching on and off of alternating current circuits with a rated voltage of up to 500V / 690V (VRE / VRE with fuses) and a frequency of 50 Hz, as well as for protection against short circuits and overload in models with fuses (fuses are not included in the delivery set ).
The double visible circuit breaker and the robust, self - extinguishing housing made of glass - fiber reinforced polyamide ensure maximum switching safety.
Frontal contact protection is provided by a protective cover. They are used as an emergency or main switch for currents from 160A to 630A in input distribution devices, distribution and control cabinets, etc.
Installed on a mounting panel. Structurally, the VRE consists of a three - pole base with a contact closing / opening mechanism and arc - extinguishing chambers, a transparent protective cover for visually determining the position of the contacts and the handle. The design of the contact terminals allows for bolted connection of busbars or conductors terminated with cable lugs. It is possible to install a lock to block on / off. Switch - disconnectors VRE are supplied with a front handle with the ability to move it to the cabinet door. The switches can be additionally equipped with an electromechanical auxiliary contact of the NO + NC status.
Advantages of VRE - type breaker - disconnectors:
1. Availability of models with fuses
2. Double visible open circuit
3. Availability of additional contacts
4. External handle on the cabinet door
5. Locking the handle position with a padlock
