Earth Blades
All disconnectors & switches can be supplied with mechanically interlocked earth blades on ‘LIVE’ side or ‘DEAD’ side if required.
Type M Pusher Disconnectors
Rated up to 52kV, 1250A, 25kA/3secs, the M.L.E. range of M type disconnectors is a cost effective, reliable, and low maintenance design. The use of nickel plated solid copper switching blades dispenses with the need for flexible cables and pantographs that historically have been proved to be a source of trouble.
The hinge end contacts are of the self-cleaning design with independent pressure springs on each side. The whole assembly makes for a very robust and reliable design.
Type R Rocking Disconnectors
The type R can be rated up to 52kV, 1600A, 25kA/3secs, in accordance with IEC 62271:2008. Each disconnector can be factory fitted with a range of optional extras, including earth blades. Supporting steelwork can be provided to suit almost any application.
Type RX Rocking Disconnectors
The M.L.E. range of type RX switches is a cost effective, reliable, and innovative design. They can be configured to suit a variety of applications and may be installed throughout the distribution network, fitted with load break interrupter heads, and fully automated to suit each customer’s individual requirements.
The RX can be rated up to 52kV, 1250A, 25kA/3secs, in accordance with IEC 62271:2008. Each high performance disconnector can be factory fitted with a range of optional extras, including earth blades. Supporting steelwork can be provided to suit almost any application.
Type RX2 Rocking Disconnectors
The MLE range of RX2 type disconnectors is a cost effective, reliable, and innovative design. They can be installed throughout the distribution network, fitted with load breaking facilities and fully automated to suit our customers’ diverse needs. The RX2 and its ancillaries have been tested up to 15kV, 800A, 25kA/3secs, to IEC 62271:2008, each disconnector can be factory fitted with optional fault making capabilities and earth blades.
Supporting steelwork can be provided to suit almost any application. A wide range of porcelain and composite insulators are available, providing a solution to almost any specification.
Optional Extras
Trip All Phase Switch-Fuse Combined Units
Trip all phase switch-fuse combined units are available up to and including 36kV, 400A 25kA/3secs.
To overcome the problems associated with ‘single phasing’ caused when only one fuse in a supply blows, MLE have developed a unique system. The design is designated a ‘TRIP-ALL PHASE UNIT’ (T.A.P.).
The principle of operation is that in the event that one or more of the TAP fuses blow, the fuse (or fuses) will swing downwards and strike a tripping bar. The tripping bar will release a spring-charged mechanism, which in turn will open the switch and isolate all 3 phases.
The switch can also be operated manually for normal switching operations.
