Finder 6K.14.9.072.4718 – 6K Series Industrial contactors

Why Choose the Finder 6K.14.9.072.4718 Industrial Contactor?

The Finder 6K.14.9.072.4718 is an industrial electromagnetic contactor designed for controlled electrical switching in industrial automation, machinery control and power distribution applications. Part of the Finder 6K industrial contactor range, this model combines a 72 V DC operating coil with three normally closed main contacts and integrated auxiliary contacts.

Featuring three normally closed (3 NC) main contacts, together with one normally open (1 NO) and one normally closed (1 NC) auxiliary contact, the Finder 6K.14.9.072.4718 provides main circuit switching alongside supplementary signalling and interlocking functions. Its 72 V DC control voltage makes it suitable for electrical control systems designed around this operating voltage.

With a listed 18 A AC-3 operational current at 400 V AC and a corresponding 7.5 kW AC-3 operational power rating, this contactor is intended for appropriately designed industrial switching applications. Its modular construction and busbar-type main connections support integration into suitable electrical control assemblies.

Industrial Electromagnetic Switching and Control

The Finder 6K.14.9.072.4718 operates through an electromagnetic mechanism controlled by its 72 V DC coil. When the operating coil is energised, the contact mechanism changes state. In a normally closed arrangement, the main contacts are closed in their normal de-energised condition and open when the contactor is actuated.

This switching behaviour makes the contactor suitable for electrical circuits specifically designed to use normally closed power contacts. The integrated auxiliary contacts provide additional switching functions that can be incorporated into control logic, status indication and electrical interlocking arrangements.

The AC-3 utilisation category is associated with specified motor starting and stopping duties, while AC-4 covers more demanding switching operations, including plugging and inching. The listed ratings must be evaluated alongside the actual load characteristics, switching frequency, protective devices and the contactor's normally closed main contact configuration.

Its modular construction and busbar-type main connections provide installation flexibility within compatible industrial electrical assemblies. Electrical engineers and panel builders should ensure that the control voltage, switching configuration and installation arrangements match the requirements of the complete system.
