Reliable 110 V DC Motor Control with Integrated Mirror Contact Feedback
The Finder 6K.04.9.110.4712 operates through an electromagnetic mechanism controlled by its 110 V DC coil. When the correct control voltage is applied, the three normally open main contacts close to supply the connected electrical load, while the normally closed auxiliary contact opens. Removing the coil supply allows the main contacts to return to their normally open positions and the auxiliary contact to return to its normally closed state.
The integrated normally closed mirror contact is a key advantage of the 4712 version. A mirror contact is mechanically associated with the main contacts so that it cannot be closed while a normally open main contact remains closed. This characteristic, defined by IEC/EN 60947-4-1, supports contactor state monitoring and diagnostic functions in suitably designed industrial control systems. However, a mirror contact alone does not establish a safety performance level, and safety-related applications require assessment of the complete system.
The contactor provides a 12 A AC-3 rating for specified squirrel-cage motor switching duties and a separate 20 A AC-1 rating for non-inductive or slightly inductive loads. Its AgSnO₂ contact material supports resistance to electrical wear, while the DIN rail construction and screw terminal connections simplify integration into industrial electrical cabinets. Appropriate motor overload protection, short-circuit protection, conductor sizing and contactor coordination must be selected for the complete installation.
Typical Applications
- Three-phase industrial motor starting and stopping circuits.
- Industrial machinery using 110 V DC control supplies.
- Power generator and standby generator auxiliary control systems.
- Industrial pumps and water treatment equipment.
- Electrical distribution boards and motor control panels.
- Contactor status monitoring and electrical interlocking circuits.
- Manufacturing machinery and automated production lines.
- Industrial conveyors and material handling equipment.
- Heating, ventilation and air conditioning (HVAC) machinery.
- OEM equipment requiring three-phase power switching with normally closed mirror contact feedback.

Frequently Asked Questions
What is the Finder 6K.04.9.110.4712 used for?
The Finder 6K.04.9.110.4712 is a mini industrial contactor designed for three-phase motor control, electrical load switching and industrial automation. It features three normally open main power contacts and one normally closed mirror auxiliary contact.
What is the coil voltage of the Finder 6K.04.9.110.4712?
The contactor uses a 110 V DC nominal operating coil. It requires an appropriately rated direct-current control supply and must not be connected directly to a 110 V AC supply.
What does the 3 NO + 1 NC contact configuration mean?
The 3 NO + 1 NC arrangement consists of three normally open main power contacts and one normally closed auxiliary contact. When the coil is energised, the main contacts close and the auxiliary contact opens.
What is the AC-3 current rating of this contactor?
The Finder 6K.04.9.110.4712 has a 12 A AC-3 operational current rating at 400 V AC. AC-3 applies to specified squirrel-cage motor starting and stopping duties.
What motor power can the Finder 6K.04.9.110.4712 control?
The contactor has a specified 5.5 kW AC-3 motor power rating at 400 V AC. Selection must also consider the motor's rated current, starting characteristics, switching frequency and required overload and short-circuit protection.
What is the AC-1 current rating?
The contactor has a 20 A AC-1 operational current rating for non-inductive or slightly inductive electrical loads. This rating must not be substituted for its AC-3 motor switching rating.
What is a mirror auxiliary contact?
A mirror auxiliary contact is a normally closed contact mechanically associated with the contactor's main power contacts so that it cannot remain closed while a normally open main contact is closed. This characteristic is defined by IEC/EN 60947-4-1 and supports contactor status monitoring.
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 appropriately rated control and signalling circuits rather than use as an additional motor power contact.
How is the Finder 6K.04.9.110.4712 mounted?
The contactor is designed for installation on a standard 35 mm DIN rail in accordance with EN 60715. This mounting arrangement supports installation inside industrial electrical cabinets and machinery control panels.
What is the difference between Finder 6K.04.9.110.4712 and 6K.04.9.110.4812?
Both models use 110 V DC coils and have a 12 A AC-3 rating. The 6K.04.9.110.4712 features three normally open main contacts and one normally closed mirror auxiliary contact, while the 6K.04.9.110.4812 features three normally open main contacts and one normally open auxiliary contact. The correct model depends on the required auxiliary contact function.
Can the Finder 6K.04.9.110.4712 be used in safety-related control circuits?
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 in accordance with the applicable functional safety requirements.
What is the operating temperature range?
The Finder Series 6K.04 contactor range supports ambient operating temperatures from −40 to +70 °C, subject to the manufacturer's specified installation and electrical loading conditions.
