The stations are intended for remote control of electric drives for machines and mechanisms in stationary plants and on ground, sea vehicles, where they are driven manually by operator, as well as for signaling associated with the specified electric drives or other electrical devices.
Stations consist of the body and cover made of high impact plastic, aluminum alloy, stainless steel or steel with corrosion-resistant coating, moreover,
overall dimensions can be changed depending on completeness.
The box bodies are equipped with cable glands and terminal clamps according to the ordering diagram. On station covers Start, Stop buttons, switches, LED indicators, instrumentation and controls, etc. can be installed.
On default terminal clamps allow connecting of two wires with cross section up to 2.5 mm each or one wire with cross section up to 4 mm. At the same time installation of clamps for large cross sections and currents is possible. Bodies and covers are sealed between each other with rubber seal.
