Finder 6K.04.9.012.4712 – 12 A Mini Industrial Contactor, 12 V DC Coil, 3 NO + 1 NC
The Finder 6K.04.9.012.4712 is a compact, four-pole industrial contactor from the Finder 6K Series, designed for reliable three-phase motor control and electrical load switching. Featuring a 12 V DC electromagnetic coil, three normally open main contacts and one normally closed auxiliary contact, this contactor offers efficient power switching and auxiliary signalling within a single DIN rail-mounted device.
Rated at 12 A AC-3 at 400 V AC, with a corresponding 5.5 kW three-phase motor rating, the 6K.04.9.012.4712 is suitable for industrial machinery, motor starters, pumps, fans and automation equipment. Its silver tin oxide (AgSnO2) contacts provide robust switching performance, while the normally closed auxiliary contact features a mirror-contact arrangement in accordance with IEC/EN 60947-4-1.
Key Benefits
- 12 V DC control coil: Suitable for low-voltage DC control systems and industrial automation equipment.
- 12 A AC-3 rating: Designed for motor switching at 400 V AC.
- 5.5 kW motor capacity: Supports appropriately rated three-phase motors.
- 3 NO + 1 NC configuration: Combines three main power contacts with an auxiliary signalling contact.
- Mirror auxiliary contact: The normally closed auxiliary contact provides a defined relationship to the main contacts for monitoring applications.
- AgSnO2 contacts: Silver tin oxide contact material provides resistance to electrical wear and contact welding.
- Compact construction: Designed for installation in space-constrained industrial control panels.
- DIN rail mounting: Compatible with standard 35 mm mounting rails.
- Accessory compatibility: Supports appropriately selected Finder 6K Series auxiliary contact and thermal overload accessories.
Reliable Three-Phase Motor Switching
The Finder 6K.04.9.012.4712 uses a 12 V DC coil to operate an electromagnetic switching mechanism. When the coil is energised, the three normally open main contacts close, allowing power to reach a connected three-phase load. Simultaneously, the normally closed auxiliary contact opens, enabling contactor status indication or electrical interlocking.
The 3 NO + 1 NC arrangement is particularly useful in motor control systems where an auxiliary feedback contact is required alongside the three main switching poles. The auxiliary normally closed contact is arranged as a mirror contact, providing a mechanically defined indication associated with the main contact state under the applicable product standard.
The contactor's 12 A AC-3 rating and 5.5 kW motor capacity at 400 V AC make it suitable for compact motor starters and machinery control assemblies. Motor overload protection and upstream short-circuit protection must be selected separately according to the connected equipment and manufacturer's coordination requirements.
Typical Applications
- Three-phase motor starting and stopping.
- Industrial automation and machine control panels.
- 12 V DC-controlled electrical switching systems.
- Pumps, fans and ventilation equipment.
- Conveyor systems and material handling machinery.
- Heating, ventilation and air conditioning installations.
- Motor starter assemblies with suitable thermal overload protection.
- Auxiliary feedback and electrical interlocking circuits.
- Industrial processing and manufacturing machinery.
- OEM electrical equipment and compact control enclosures.
Installation and Compatibility
The Finder 6K.04.9.012.4712 is designed for mounting on a standard 35 mm DIN rail inside a suitable electrical enclosure. Its box-clamp terminals accept appropriately prepared conductors, and its compact construction helps conserve space in control cabinets.
The contactor can be used with compatible Finder 6K Series accessories, including appropriately selected auxiliary contact modules and 6K.T0 thermal overload relays. The overload relay setting must match the motor's rated current, and the upstream protective device must comply with the relevant short-circuit coordination requirements.

Frequently Asked Questions
What is the Finder 6K.04.9.012.4712 used for?
The Finder 6K.04.9.012.4712 is a mini industrial contactor designed for three-phase motor switching, industrial machinery control and electrical automation. It combines three normally open main contacts with one normally closed auxiliary contact.
What coil voltage does the Finder 6K.04.9.012.4712 require?
This contactor uses a 12 V DC electromagnetic coil. It should be operated from a suitable DC control supply rather than an AC coil supply.
What are the current and motor power ratings?
The contactor is rated at 12 A AC-3 at 400 V AC, corresponding to a 5.5 kW three-phase motor rating. Its AC-1 current rating is 20 A at 690 V AC, subject to the manufacturer's operating conditions.
What does 3 NO + 1 NC mean?
The contactor has three normally open main contacts that close when the coil is energised and one normally closed auxiliary contact that opens simultaneously. The auxiliary contact uses a mirror-contact arrangement in accordance with IEC/EN 60947-4-1.
Can the Finder 6K.04.9.012.4712 be used with a thermal overload relay?
