22.34.0.048.4620 Finder contactor 4 pole 25A AC/DC 48V 3NO+1NC

Why Choose the Finder 22.34.0.048.4620 Modular Contactor?

The Finder 22.34.0.048.4620 is a 25 A four-pole modular installation contactor designed for reliable switching of electrical loads in lighting control, building automation and electrical distribution systems. Part of the Finder 22 Series, this contactor combines a 48 V AC/DC silent control coil with two normally open and two normally closed contacts.

Its 2NO + 2NC contact configuration provides complementary switching from a single control signal. When the coil is energised, the two normally open contacts close and the two normally closed contacts open. This makes the contactor useful for applications requiring coordinated switching, change-of-state functions and appropriately engineered electrical control arrangements.

Featuring silver tin oxide (AgSnO2) contacts, an integrated LED, mechanical operating indication and varistor-protected coil, the Finder 22.34.0.048.4620 is particularly suited to professional installations where reliable switching and convenient status indication are important. Its 35 mm-wide DIN rail housing provides a compact solution for distribution boards and control panels.

Flexible Two Normally Open and Two Normally Closed Contact Operation

The Finder 22.34.0.048.4620 provides coordinated switching through a 2NO + 2NC contact arrangement. With no control voltage applied, the two normally open contacts remain open and the two normally closed contacts remain closed. Applying the rated 48 V AC/DC control voltage reverses these states, allowing the contactor to control complementary functions simultaneously.

This arrangement is useful in electrical systems where one group of circuits must be enabled while another is disabled. It can also support appropriately designed change-of-state and control arrangements. The contactor's contacts should not be assumed to provide a safety-rated interlock without the necessary system design and verification.

The device uses AgSnO2 contact material, which Finder specifies for lighting and higher-inrush switching applications. This makes the contactor a suitable candidate for compatible lighting circuits, including installations with electronic ballasts and LED drivers. However, the number and rating of connected drivers must be checked against the manufacturer's applicable lamp-load ratings and inrush-current limits.

The 48 V AC/DC silent coil offers flexibility for automation systems using either alternating-current or direct-current control supplies. Its integrated varistor helps limit switching transients, while the mechanical and LED indicators allow installers to observe contactor operation during commissioning and troubleshooting.

The contactor is designed for continuous-duty operation, so it can remain energised for extended periods within its specified operating conditions. Its reinforced insulation provides separation between the control coil and power contacts, helping support safe integration into appropriately engineered electrical systems.

With a 35 mm housing width, the Finder 22.34.0.048.4620 occupies approximately two standard DIN rail modules. This compact construction is particularly valuable in lighting control panels and distribution boards where space is limited.
