Cassettes and frames
Cassettes and frames for building medium voltage switchgear
Fixed parts for fitting circuit breakers/contactors and pre-assembled modules for constructing medium voltage switchgear up to 40.5 kV, 2500 A, 25 kA.
Compact dimensions and limited weights of the frames (fixed parts) make them the ideal solution for replacing fixed circuit-breakers with withdrawable circuit breakers, for retrofitting activities and for upgrading obsolete switchgear to the new standards.
Complete modules allow medium-voltage air-insulated switchgear to be constructed with the same rated currents as those of the enclosure.
- Modular structure
- Mechanical and electromechanical safety locks against incorrect operations
- Suited to making switchgear for circuit-breaker / contactor racking in / out with door closed
- Version with earthing switch with making capacity
