Why Choose the Finder 6K.04.9.048.4709 Industrial Contactor?
The Finder 6K.04.9.048.4709 is a compact mini industrial contactor from the Finder Series 6K, designed for dependable electrical switching in industrial automation, motor control and machinery applications. Featuring a 48 V DC nominal operating coil, it provides electromagnetic switching for compatible DC control systems.
This contactor features three normally open main contacts and one normally closed auxiliary mirror contact (3 NO + 1 NC). Its main contacts are rated at 9 A AC-3 at 400 V AC, with a corresponding 4 kW three-phase motor rating. The normally closed auxiliary contact provides a monitoring function and is rated at 2 A AC-15 at 400 V AC.
The Finder 6K.04.9.048.4709 combines silver tin oxide (AgSnO2) contacts, screw-terminal connections and 35 mm DIN rail mounting in a compact design. Its mirror-contact arrangement makes it particularly useful for control systems requiring feedback about the state of the main power contacts.

Reliable 48 V DC Motor Control with Auxiliary Mirror Contact Monitoring
The Finder 6K.04.9.048.4709 operates through an electromagnetic coil controlled by a 48 V DC supply. When the coil is energised, the three normally open main contacts close to supply the connected electrical load, while the normally closed auxiliary mirror contact opens. When the coil is de-energised, the main contacts return to their normally open positions and the auxiliary contact returns to its normally closed state, provided the mechanism is operating correctly.
The 3 NO + 1 NC configuration is particularly useful in three-phase motor control circuits requiring auxiliary contact-state feedback. The mirror contact is mechanically arranged so that it cannot be closed simultaneously with a normally open main contact under the conditions defined by EN 60947-4-1. Its 9 A AC-3 rating, compact DIN rail-mounted design and AgSnO2 contact system support integration into industrial control panels. Suitable overload protection, short-circuit coordination and control-system design remain essential.

Frequently Asked Questions
What is the Finder 6K.04.9.048.4709 used for?
The Finder 6K.04.9.048.4709 is a mini industrial contactor designed for electrical load switching, particularly three-phase motor control, in industrial automation and machinery applications. Its auxiliary mirror contact also supports contact-state monitoring.
What coil voltage does the Finder 6K.04.9.048.4709 require?
The contactor uses a 48 V DC nominal operating coil. The control supply must remain within the manufacturer's specified operating voltage limits.
What contact configuration does the Finder 6K.04.9.048.4709 have?
The contactor has three normally open main contacts and one normally closed auxiliary mirror contact (3 NO + 1 NC).
What is the AC-3 current rating of the Finder 6K.04.9.048.4709?
The contactor has a 9 A rated operational current at 400 V AC under AC-3 conditions. This rating applies to the specified motor-switching utilisation category.
What motor power can the Finder 6K.04.9.048.4709 control?
The contactor has a 4 kW motor rating at 400 V AC under AC-3 conditions. Motor suitability must be assessed against the actual load current, starting characteristics and operating duty.
What is the purpose of the normally closed mirror contact?
The normally closed auxiliary mirror contact provides contact-state feedback and is designed according to EN 60947-4-1. It is mechanically arranged so that it cannot be closed simultaneously with a normally open main contact under the standard's defined conditions.
What is the auxiliary contact rating of the Finder 6K.04.9.048.4709?
The normally closed auxiliary contact is rated at 2 A under AC-15 conditions at 400 V AC. It is intended for compatible auxiliary control duties rather than the main motor load.
How is the Finder 6K.04.9.048.4709 mounted?
