Reliable Three-Phase Motor Control with Integrated Auxiliary Switching
The Finder 6K.04.8.110.4809 operates using an electromagnetic coil supplied with 110 V AC. When the coil is energised, the contactor closes its three normally open main contacts, allowing electrical power to reach a connected three-phase load. At the same time, its normally open auxiliary contact closes, providing an additional signal or control path.
The integrated 3 NO + 1 NO arrangement is particularly useful in industrial motor control circuits where an auxiliary contact is required for holding circuits, contactor status feedback or control interlocking. By incorporating the auxiliary contact within the main contactor assembly, the device helps simplify panel wiring and reduce the need for additional components.
The 9 A AC-3 rating at 400 V AC identifies this model as the 9 A motor-switching variant within the Finder 6K.04 range. Its compact dimensions, durable AgSnO2 contacts and DIN rail installation make it suitable for machinery manufacturers, electrical panel builders and industrial maintenance applications.
When used for motor starting, the contactor should be combined with appropriately selected overload and short-circuit protection. Motor compatibility must be determined from the applicable utilisation category, motor nameplate current and manufacturer coordination data.
Typical Applications
- Three-phase industrial motor starting and stopping.
- Industrial automation and machinery control panels.
- Pumps, fans and ventilation systems.
- Conveyor systems and material handling equipment.
- Heating, ventilation and air conditioning installations.
- Electrical distribution and power control panels.
- Industrial manufacturing and processing machinery.
- Motor starter assemblies with suitable overload protection.
- Auxiliary signalling, holding circuits and control interlocking.
- OEM machinery and compact industrial control enclosures.

Frequently Asked Questions
What is the Finder 6K.04.8.110.4809 used for?
The Finder 6K.04.8.110.4809 is a compact industrial electromagnetic contactor used for three-phase motor control, machinery automation and electrical switching. It features three normally open main contacts and one normally open auxiliary contact.
What control voltage does the Finder 6K.04.8.110.4809 require?
This contactor requires a nominal 110 V AC control supply to energise its electromagnetic coil. It is designed for AC control voltage rather than a 110 V DC coil supply.
What is the current rating of the Finder 6K.04.8.110.4809?
The contactor has a rated operational current of 9 A under AC-3 conditions at 400 V AC. This rating applies to the specified motor-switching utilisation category; other load types must be checked against their relevant ratings.
What does the 3 NO + 1 NO contact configuration mean?
The contactor has three normally open main contacts for three-phase power switching and one normally open auxiliary contact for signalling or control. All four contacts close when the coil is energised and return to their open positions when the coil is de-energised.
How is the Finder 6K.04.8.110.4809 installed?
The contactor is designed for DIN rail mounting within a suitable electrical enclosure. It has a compact 45 mm width, IP20 protection and terminals suitable for conductors in the specified 0.5–2.5 mm² range.
