Isolator switches and their enclosuresoffer tough robust operation throughout theyears.

designed to neverlet you down4

A carefully studied and complete line rangingfrom 16A to 100A with emergency controlversions. They are also equipped withauxiliary contacts for remote indication ofmain contacts position.

3 TECHNIQUESAND ADVANTAGES

the new frontier of controlsthe new frontier of controlsUNBEATABLE

An AC23A – AC3 installation class, con-ditional short circuit current 10,000Aand guaranteed isolation are but a few ofthe superbly performing features of theisolator switches. At the maximum level ofwhat the market offers today, they allowdirect control of even highly inductiveloads (such as pumps, exhaust fans,mills, compressors, etc.) and eliminatecostly machine shutdowns with a subse-quent increase in the installation’s yield.

NO DOWNGRADING

In addition to making wiring easier, thespacious interior ensures maximumthermal dissipation thereby eliminatingdowngrading and premature ageing.As a consequence provides ample cablingand glanding space.

MULTIPURPOSE

May be integrated with TER Seriesdistribution boards which allowmultipurpose batteries to be created fordirect control of each service or as a batterymain switch.

MODERN

With the knob inserted in the front panel,the packaging meets the most demandingaesthetic needs and reduces the ingressof grime and dirt. This makes the productideal for areas subject to inspection. Theergonomic knob makes operating with workgloves easy.
