Why Choose the Finder 22.22.9.012.4000 Modular Contactor?
The Finder 22.22.9.012.4000 is a reliable 20 A modular contactor with a 12 V DC coil, designed for remote switching of electrical loads in industrial automation, building management and electrical distribution systems. As part of the Finder Series 22 modular contactor range, it provides dependable electromechanical switching for lighting circuits, electrical control panels and automation equipment.
Featuring two normally open (DPST-NO) contacts, the Finder 22.22.9.012.4000 allows two electrical circuits to be switched simultaneously using a single control signal. Its monostable operating mechanism ensures that the contacts return to their normally open positions when the coil is de-energised. The silver tin oxide (AgSnO₂) contact material is particularly suitable for applications involving lighting loads and electrical equipment with relatively high inrush currents.
With a 20 A rated contact current, 12 V DC control coil and 35 mm DIN rail mounting, this modular contactor offers a practical solution for electrical installers, panel builders and automation engineers. Its compact construction, screw terminals and integrated test button simplify installation, commissioning and maintenance in industrial and commercial electrical systems.

Modular contactors such as the Finder 22.22.9.012.4000 provide an efficient method of controlling electrical loads through a separate low-voltage control circuit. When the 12 V DC coil is energised, the contactor closes its two normally open contacts, allowing connected electrical circuits to operate. When the coil supply is removed, both contacts return to their open positions.
The Finder Series 22 is designed for electrical installation and automation applications where compact construction and reliable switching are important. The two-pole arrangement enables coordinated switching of compatible loads, while the silver tin oxide contacts support applications such as lighting control and other electrical circuits with demanding switching characteristics. DIN rail mounting and screw terminal connections simplify integration into distribution boards, control cabinets and building automation installations.
