22.32.0.048.4320 Finder contactor 2pole 25A AC/DC 48V 1 NO 1NC

Why Choose the Finder 22.32.0.048.4320 Modular Contactor?

The Finder 22.32.0.048.4320 is a 25 A two-pole modular contactor designed for reliable electrical load switching in building automation, lighting control and industrial electrical installations. Part of the Finder 22 Series, this installation contactor features a 48 V AC/DC operating coil and two normally open contacts, providing convenient remote switching of compatible electrical circuits.

With a 2 NO (DPST-NO) contact configuration, the Finder 22.32.0.048.4320 enables two circuits to be switched simultaneously using a single control signal. Its 25 A AC-1/AC-7a contact rating makes it suitable for appropriately rated resistive and slightly inductive loads, while its 10 A AC-3 switching capability supports compatible motor-control applications.

The contactor combines a silent AC/DC operating coil, integrated varistor protection and DIN rail mounting for practical installation in electrical distribution boards and control panels. Mechanical and LED status indicators provide convenient operating-state identification, making this model suitable for professional electrical installations requiring dependable switching and straightforward maintenance.

Reliable Electrical Switching for Building Automation and Motor Control

Modular contactors are widely used to switch electrical loads through separate control circuits. The Finder 22.32.0.048.4320 uses a 48 V AC/DC electromagnetic coil to operate two normally open contacts, allowing compatible electrical circuits to be controlled together from a common signal.

When the operating coil is energised, both normally open contacts close and complete their respective load circuits. Removing the coil supply returns the contactor to its de-energised state, opening both contacts. This switching arrangement is useful for lighting installations, building services and electrical control systems requiring predictable operation.

The 25 A AC-1/AC-7a rating supports compatible resistive and slightly inductive loads, while the 10 A AC-3 rating provides a separate reference for suitable motor-switching applications. These utilisation categories are important because electrical loads can have substantially different starting currents and switching demands.

The silent AC/DC coil makes the contactor particularly useful in installations where audible switching equipment may be undesirable. Integrated varistor protection, mechanical and LED status indication, and reinforced insulation between the coil and contacts further support practical operation and maintenance.

Before installation, the connected loads must be checked against Finder's specified utilisation categories, contact ratings and inrush-current limits. Motor loads, LED drivers and other equipment with significant starting currents require particular attention to ensure the contactor is correctly selected.
