Reliable Three-Phase Motor Switching with Integrated Mirror Contact Feedback
The Finder 6K.04.8.024.4709 uses an electromagnetic operating mechanism controlled by its 24 V AC coil. When the coil is energised, the three normally open main contacts close to supply the connected electrical load, while the normally closed auxiliary contact opens. When the coil supply is removed, the main contacts return to their open positions and the auxiliary contact returns to its normally closed state.
A key advantage of the 4709 contact configuration is its integrated normally closed mirror auxiliary contact. Designed in accordance with IEC/EN 60947-4-1, a mirror contact is mechanically associated with the main contacts so that it cannot be closed at the same time as a normally open main contact remains closed. This characteristic supports contactor monitoring and diagnostic functions, although any safety-related application must be assessed as part of the complete control system.
The contactor provides a 9 A AC-3 rating for specified motor switching duties and a separate 20 A AC-1 rating for non-inductive or slightly inductive loads. Its AgSnO₂ contact material, compact housing and DIN rail mounting support reliable installation in industrial electrical panels. Appropriate motor overload protection, short-circuit protective devices and correctly rated conductors must be selected for the complete installation.

Frequently Asked Questions
What is the Finder 6K.04.8.024.4709 used for?
The Finder 6K.04.8.024.4709 is a mini industrial contactor used for three-phase motor switching, industrial machinery control and electrical load management. It features three normally open main contacts and one normally closed auxiliary mirror contact.
What is the coil voltage of the Finder 6K.04.8.024.4709?
The contactor uses a 24 V AC nominal operating coil. It requires an appropriately rated alternating-current control supply and should not be connected directly to a 24 V DC supply.
What does the 3 NO + 1 NC contact configuration mean?
The contactor contains three normally open main power contacts and one normally closed auxiliary contact. The three main contacts close when the coil is energised, while the auxiliary contact opens. This arrangement provides three-phase power switching and a separate contact for control or monitoring functions.
What is the motor switching current rating?
The Finder 6K.04.8.024.4709 has a 9 A AC-3 operational current rating at 400 V AC. The AC-3 rating applies to specified squirrel-cage motor switching duties.
What motor power can the Finder 6K.04.8.024.4709 control?
The contactor is rated for 4 kW AC-3 motor switching at the manufacturer's specified operating voltage. Motor selection must also consider the motor's rated current, starting characteristics, switching duty and required overload protection.
What is a mirror contact on an industrial contactor?
A mirror contact is a normally closed auxiliary contact mechanically linked to the main contacts so that it cannot remain closed when a normally open main contact is closed. This configuration, defined by IEC/EN 60947-4-1, supports contactor status monitoring and diagnostic circuits.
What is the rating of the normally closed auxiliary contact?
The normally closed auxiliary contact has a specified 2 A AC-15 rating at 400 V AC. It is intended for appropriate control circuit duties rather than use as an additional 9 A motor power contact.
How is the Finder 6K.04.8.024.4709 mounted?
The contactor mounts onto a standard 35 mm DIN rail in accordance with EN 60715. Its compact 45 mm-wide housing supports installation in industrial control panels and electrical cabinets.
What is the difference between Finder 6K.04.8.024.4709 and 6K.04.8.024.4312?
The 6K.04.8.024.4709 has a 9 A AC-3 rating, a 4 kW motor rating and a 3 NO + 1 NC contact arrangement with an auxiliary mirror contact. The 6K.04.8.024.4312 belongs to the 12 A AC-3, 5.5 kW version and has four normally open contacts. They are not direct substitutes without checking the electrical ratings and contact arrangement.
What is the operating temperature range?
The Finder 6K.04.8.024.4709 is specified for an ambient operating temperature range of −40 to +70 °C, subject to the manufacturer's applicable installation and electrical loading conditions.
Can this contactor be used in a safety-related motor control circuit?
The normally closed mirror contact can support monitoring in suitably designed safety-related control systems. However, the contactor alone does not establish a safety performance level. The complete system must be designed and validated using the relevant safety standards, protective devices and diagnostic arrangements.
