Finder 6K.04.8.230.4809 – 6K Series Industrial contactors

Why Choose the Finder 6K.04.8.230.4809 Mini Industrial Contactor?

The Finder 6K.04.8.230.4809 is a compact, four-pole 9 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 four normally open contacts (4 NO), it provides coordinated switching for industrial machinery, electrical distribution equipment and motor control circuits.

Part of the established Finder Series 6K mini industrial contactor range, the 6K.04.8.230.4809 offers a 20 A AC-1 resistive load rating, 9 A AC-3 motor switching capability and a 4 kW AC-3 motor power rating at 440 V AC. Its four normally open contacts comprise a three-pole normally open arrangement with an additional normally open contact, providing flexibility for appropriately designed power and control circuits.

The contactor features silver tin oxide (AgSnO₂) contacts, a compact 45 mm-wide housing, screw terminal connections and standard 35 mm DIN rail mounting. With an IP20 protection rating and an operating temperature range of −40 to +70 °C, it is a practical solution for electrical panel builders, OEM machinery manufacturers and industrial maintenance engineers.

Reliable Four-Pole Switching for Industrial Motors and Electrical Control Systems

The Finder 6K.04.8.230.4809 operates through an electromagnetic contactor mechanism controlled by its 230 V AC coil. When the coil is energised, all four normally open contacts close, allowing the connected electrical circuits to operate. Removing the coil supply returns the contacts to their normally open positions, providing controlled interruption of the switched circuits.

The contactor's 9 A AC-3 rating applies to specified squirrel-cage motor starting and stopping duties, while its separate 20 A AC-1 rating covers non-inductive or slightly inductive electrical loads. These utilisation categories represent different electrical operating conditions and must be considered when selecting the contactor for motors, heating equipment or other electrical loads. The AgSnO₂ contact material helps resist electrical wear and contact welding during appropriately rated switching operations.

The four normally open contact configuration provides flexibility for electrical assemblies requiring multiple conductors or circuits to be switched together. Its compact construction and 35 mm DIN rail mounting support efficient integration into industrial control panels. The additional normally open contact must be used within its applicable rating, and switching a neutral conductor requires compliance with the relevant electrical installation requirements. Suitable overload protection, short-circuit protection and conductor sizing remain essential for the complete system.
