The Finder 20.22.8.120.4000 is a compact and dependable modular step relay designed for impulse-controlled switching in lighting, building automation and electrical distribution applications. As part of the Finder Series 20, it changes contact state whenever its coil receives a momentary control pulse.
Its electromechanical latching operation enables electrical loads to be controlled from multiple momentary push-buttons without requiring the coil to remain continuously energised. A mechanical position indicator and test button support convenient inspection and manual operation during installation, commissioning and maintenance.
With two normally open contacts rated at 16 A, a 120 V AC coil and silver tin oxide contact material, the 20.22.8.120.4000 provides dependable switching of compatible electrical loads. Its compact DIN-rail enclosure and screw terminals simplify installation inside distribution boards and control panels.
A modular step relay changes its output state each time a momentary voltage pulse is applied to the coil. This allows one electrical load to be switched from several push-button locations while avoiding complex conventional multi-way switching arrangements.
The Finder Series 20 is designed for installation in modular distribution equipment. Its latching mechanism, silver tin oxide contacts, contact-status indication and manual test facility make the 20.22.8.120.4000 suitable for building-control systems requiring reliable impulse operation.
