Why Choose the Finder 22.24.9.024.4000 Modular Contactor?
The Finder 22.24.9.024.4000 is a compact and reliable 20 A modular contactor with a 24 V DC coil, designed for remote electrical load switching in commercial buildings, industrial installations and automation systems. As part of the Finder Series 22 modular contactor range, it provides dependable switching performance for lighting, heating, electrical distribution and building management applications.
This modular contactor features a two-pole normally closed (2 NC) contact configuration, allowing connected electrical circuits to remain closed when the control coil is de-energised and open when the coil is energised. Its electromagnetic operating mechanism supports reliable control through compatible switches, controllers, timers and building automation equipment.
With a 20 A rated switching current, 24 V DC control coil and maximum AC switching voltage of 400 V AC, the Finder 22.24.9.024.4000 is suitable for a wide range of electrical control applications. Its compact 17.5 mm wide DIN rail-mounted housing enables straightforward installation inside electrical distribution boards and control panels.

Reliable Electrical Load Switching for Automation Systems
Modular contactors such as the Finder 22.24.9.024.4000 provide electrically controlled switching between a low-voltage control circuit and connected power circuits. The 24 V DC operating coil enables the contactor to be controlled by compatible automation equipment, while the main contacts handle the connected electrical load within their specified ratings.
Unlike normally open contactors, this model incorporates two normally closed contacts. When the coil is not energised, both contacts remain closed. Applying the rated control voltage energises the coil and opens the contacts, interrupting the connected circuits. This arrangement is useful where the application requires normally closed switching behaviour.
The Finder Series 22 is designed for electrical installation and building automation applications where compact dimensions, reliable switching and straightforward panel integration are important. Its DIN rail mounting arrangement and screw terminal connections make it suitable for electrical installers, panel builders and automation engineers.
