Why Choose the Finder 22.23.9.048.4000 Modular Contactor?
The Finder 22.23.9.048.4000 is a 20 A modular contactor from the Finder Series 22 range, featuring a 48 V DC operating coil and a 1 normally open + 1 normally closed (1 NO + 1 NC) contact configuration. Designed for DIN rail installation, this electromagnetic switching device provides a compact solution for electrical distribution, lighting control, building automation and industrial control applications.
The 1 NO + 1 NC contact arrangement allows two circuits to operate in complementary states. When the 48 V DC coil is energised, the normally open contact closes while the normally closed contact opens. When the coil is de-energised, both contacts return to their normal positions. This makes the Finder 22.23.9.048.4000 suitable for applications requiring coordinated electrical switching from a single control signal.
With AgSnO2 silver tin oxide contact material, a narrow 17.5 mm modular housing and standard 35 mm DIN rail mounting, the contactor is designed for dependable switching and efficient use of panel space. Its 48 V DC coil makes it particularly suitable for installations using compatible DC control power supplies and automation equipment.

48 V DC Control with Complementary NO and NC Switching
The Finder 22.23.9.048.4000 operates through an electromagnetic coil designed for a nominal 48 V DC supply. When the correct control voltage is applied, the contactor changes the state of its two switching contacts. The normally open contact closes, while the normally closed contact opens.
This arrangement provides a practical solution where two circuits must respond in opposite ways to the same control signal. For example, one circuit may be enabled while another is disconnected. Such functionality is useful in building automation, auxiliary electrical control and industrial switching arrangements.
The contactor provides a 20 A rated contact current and uses AgSnO2 silver tin oxide contact material. Silver tin oxide is commonly selected for switching applications where reliable contact performance is important, including appropriately rated lighting and electrical power loads.
As with all modular contactors, the permitted switching load depends on the electrical characteristics of the connected equipment. Resistive loads, inductive loads and electronic lighting drivers can have significantly different operating and inrush currents. The applicable Finder switching ratings should therefore be checked before selecting the contactor for a particular circuit.
The 48 V DC coil is an important distinguishing characteristic of this model. It is intended for DC control supplies and should not be confused with the 24 V DC version, 22.23.9.024.4000, or with Series 22 models featuring AC coils. Applying an incorrect coil voltage can prevent correct operation or damage the device.
Its compact 17.5 mm width allows installation in space-constrained electrical panels. Standard 35 mm DIN rail mounting and screw terminals support efficient assembly and maintenance. Installation should be carried out by a competent person using suitable circuit protection, conductor sizing and enclosure arrangements.
