The ELTAKO impulse relay S12-100-230V 1TE 1S 16A 250V (21100030) is a compact, reliable switching device for professional electrical installations in residential, commercial and industrial buildings. Designed for mounting on DIN rails with a width of just 1 modular unit (1TE), it offers space-saving integration in distribution boards. With a switching contact (1S) rated for 16 A at 250 V AC, this impulse relay is suitable for typical lighting circuits and other moderate loads.
Technically, the S12-100-230V is designed for a control voltage of 230 V AC and works as a step-by-step or impulse switch: each electrical impulse on the control input changes the switching state of the output contact (ON/OFF). This makes it ideal for centrally controlling lighting circuits from multiple push-buttons, such as in stairwells, corridors, offices, public buildings and multi-storey residential houses. The device's clear functional design helps to reduce wiring complexity and enables the retrofitting of convenient lighting control without complex electronics.
Typical applications include staircase lighting circuits, corridor and hall lighting, central switching of lighting groups, as well as the control of signal lamps or smaller consumers within the permissible power range. Electricians and planners appreciate impulse relays like the S12-100-230V because they permit the use of simple momentary push-buttons instead of multiple-way switching, which simplifies planning and reduces copper usage in multi-way circuits.
Key advantages of this ELTAKO impulse relay include its robust construction, long service life and suitability for continuous use in building installations. The compact 1TE format saves space in the distribution board, making it particularly attractive for modern, highly equipped installations where every modular unit counts. The clearly defined technical data and standardized dimensions facilitate planning, documentation and replacement in existing systems.
