Finder 6K.04.8.110.4812 – 6K Series Industrial contactors

Why Choose the Finder 6K.04.8.110.4812 Industrial Contactor?

The Finder 6K.04.8.110.4812 is a 12 A industrial contactor from the Finder Series 6K range, designed for dependable switching and control of electrical motors, machinery and industrial loads. Featuring a 110 V AC operating coil, three normally open main contacts and one integrated normally open auxiliary contact, this contactor provides a practical solution for three-phase motor control and industrial automation applications.

With a rated operational current of 12 A at 400 V AC under AC-3 duty, the Finder 6K.04.8.110.4812 is suitable for appropriately rated motor switching applications. Its 3 NO + 1 NO contact configuration allows the three main contacts to switch a three-phase electrical load while the auxiliary contact can provide control-circuit feedback, signalling or an electrical holding function.

The contactor incorporates silver tin oxide (AgSnO2) contact material, a compact 45 mm-wide housing and DIN rail mounting for integration into electrical control panels. Its IP20 protection rating, screw-terminal wiring arrangement and industrial operating temperature range make it a useful component for panel builders, electrical engineers and OEM equipment manufacturers.

Reliable Three-Phase Motor Control with Integrated Auxiliary Switching

The Finder 6K.04.8.110.4812 operates through a 110 V AC electromagnetic coil. When the coil is energised, the contactor closes its three normally open main contacts and its integrated normally open auxiliary contact. When the coil is de-energised, the contacts return to their open positions, allowing a control circuit to start and stop the connected electrical load.

The three main contacts are particularly useful for three-phase motor switching, where the contactor must simultaneously control the supply conductors to a motor. The manufacturer's 12 A AC-3 rating at 400 V AC and 5.5 kW motor power rating provide a clear basis for selecting the contactor for compatible motor-control applications.

The integrated normally open auxiliary contact offers an additional control function without requiring a separate external contact block for basic auxiliary switching. It can be incorporated into a contactor holding circuit, provide an electrical indication that the contactor has operated or supply a signal to another part of the control system. The auxiliary contact must be used within its own applicable electrical ratings and should not be treated as an additional 12 A motor-power contact.

The AgSnO2 contact material provides a robust contact interface for electrical switching. The contactor's 45 mm width and DIN rail mounting arrangement make it practical for installation in industrial electrical enclosures where space, accessibility and organised wiring are important.

When selecting the contactor, engineers should consider the motor's full-load current, starting characteristics, switching frequency, utilisation category and required short-circuit protection. The AC-3 rating is intended for appropriate motor starting and stopping duties; other operating conditions, including frequent reversing, plugging or inching, may require selection according to a different utilisation category.
