22.32.0.120.4520 Finder contactor 2pole 25A AC/DC 110/125V all NO

Why Choose the Finder 22.32.0.120.4520 Modular Contactor?

The Finder 22.32.0.120.4520 is a 25 A two-pole modular installation contactor designed for electrical load switching in building automation, lighting control and industrial electrical installations. Part of the Finder 22 Series, this contactor features a 120 V AC/DC operating coil and a combination of one normally open and one normally closed contact.

Its 1 NO + 1 NC contact configuration enables complementary switching of two electrical circuits using a common control signal. When the operating coil is energised, the normally open contact closes while the normally closed contact opens, providing a practical arrangement for electrical control, change-of-state signalling and coordinated load switching.

The Finder 22.32.0.120.4520 combines 25 A rated contacts, silver tin oxide (AgSnO2) contact material and a silent AC/DC coil with integrated varistor protection. Designed for DIN rail installation, it also incorporates mechanical and LED operating indicators to simplify status identification during commissioning and maintenance.

Reliable Complementary Switching for Electrical Control and Automation

Modular contactors provide a practical means of controlling electrical equipment through a separate operating circuit. The Finder 22.32.0.120.4520 uses a 120 V AC/DC electromagnetic coil to operate two contacts with opposite normal states, enabling coordinated control of compatible electrical circuits.

When the coil is de-energised, the normally open contact remains open and the normally closed contact remains closed. Applying the rated operating voltage changes both contact states: the normally open contact closes and the normally closed contact opens. This arrangement can be useful for switching arrangements that require one circuit to operate while another is disconnected.

The 25 A rated contacts and AgSnO2 contact material make the contactor suitable for electrical switching applications within the specified ratings. Its separate 10 A AC-3 rating provides an important reference when assessing compatible motor loads, which can impose substantially different switching demands from resistive equipment.

The silent AC/DC coil helps reduce audible operating noise, while integrated varistor protection supports electrical control circuit reliability. Mechanical and LED indicators provide convenient confirmation of the contactor's operating state during inspection, maintenance and commissioning.

When specifying the Finder 22.32.0.120.4520, installers should assess the connected load's utilisation category, starting current and operating voltage. In particular, motor loads and lighting equipment with high inrush currents should be checked against the applicable Finder switching ratings rather than relying solely on the nominal 25 A contact rating.
