Product Overview
The RST 25 is an electrical voltage control relay designed for integration into control and distribution systems where continuous voltage supervision is required.
It operates at 3×415V / 185–245V AC with a rated frequency of 50/60Hz. Its guide rail mounting design allows convenient installation inside electrical cabinets and control panels, while an operating temperature range of −20°C to +55°C supports use in a wide range of industrial and commercial electrical environments.
The compact housing and clearly arranged front indicators make the RST 25 suitable for engineers and panel builders requiring a practical voltage monitoring component for electrical control applications.
