Finder 6K.04.8.230.4712 – 6K Series Industrial contactors

Why Choose the Finder 6K.04.8.230.4712 Mini Industrial Contactor?

The Finder 6K.04.8.230.4712 is a compact 12 A AC-3 industrial contactor designed for reliable motor control, electrical load switching and industrial automation applications. Featuring a 230 V AC operating coil and a 3 NO + 1 NC contact configuration, it combines three normally open power contacts with one normally closed contact for auxiliary switching and control functions.

Part of the established Finder Series 6K mini industrial contactor range, this model offers a 20 A AC-1 resistive load rating, a 12 A AC-3 motor switching rating and a 5.5 kW AC-3 motor power rating at the specified operating voltage. Its compact 45 mm-wide housing and standard 35 mm DIN rail mounting make it particularly suitable for industrial control panels, electrical distribution assemblies and OEM machinery.

The Finder 6K.04.8.230.4712 incorporates silver tin oxide (AgSnO₂) contacts, screw terminal connections and an IP20 protection rating. Designed for industrial applications including motors, pumps, generators and automated machinery, it provides a practical switching solution where dependable electromagnetic operation and a 230 V AC control supply are required.

Reliable Industrial Motor Control with 230 V AC Electromagnetic Switching

The Finder 6K.04.8.230.4712 uses an electromagnetic operating mechanism controlled by its 230 V AC coil. When the coil is energised, the normally open contacts close and the normally closed contact opens. Removing the coil supply returns the contacts to their normal positions, allowing the contactor to provide controlled electrical switching within an appropriately designed circuit.

The contactor's 12 A AC-3 rating applies to specified industrial motor switching duties, including the starting and stopping of suitable squirrel-cage motors. Its separate 20 A AC-1 rating applies to non-inductive or slightly inductive loads. These utilisation categories describe different switching conditions and must be considered when selecting the contactor for motors, heaters or other electrical equipment.

The AgSnO₂ contact system provides resistance to electrical wear, while the compact housing and 35 mm DIN rail mounting support efficient installation in industrial control panels. The additional normally closed contact can be incorporated into suitable electrical interlocking or status indication circuits, subject to its applicable contact rating and the complete system design. Appropriate overload protection, short-circuit protection and conductor sizing remain essential for safe operation.
