Reliable 110 V DC Control for Industrial Motor Switching
The Finder 6K.04.9.110.4312 enables an industrial 110 V DC control circuit to operate AC electrical loads through an electromagnetic switching mechanism. When the coil is energised, all four normally open contacts close, connecting the controlled circuits. When coil power is removed, the contacts return to their normally open positions. This operating principle makes the contactor suitable for automated motor starting, remote load switching and electrical control systems.
The Finder Series 6K.04 is particularly useful in compact industrial installations requiring reliable motor switching performance. Its 12 A AC-3 rating corresponds to a 5.5 kW motor rating at 400 V AC, while its 20 A AC-1 rating applies to suitable non-inductive or slightly inductive loads. These utilisation categories describe different switching conditions and must be considered when selecting a contactor for motors, heating equipment or other electrical loads.
DIN Rail Installation and Motor Protection
The Finder 6K.04.9.110.4312 is designed for mounting onto a standard 35 mm DIN rail, allowing convenient integration into industrial electrical panels alongside circuit breakers, motor protection devices and automation components. Its screw terminal connections provide a practical method of securing conductors, while the IP20 housing is intended for installation inside a suitable protective enclosure.
For dependable operation, the contactor should be used with a correctly rated 110 V DC coil supply, appropriate short-circuit protection and suitable motor overload protection. The Finder 6K.T0 thermal overload relay range provides compatible protection options for Series 6K.04 contactors. Where the coil is switched by a PLC output or another electronic device, appropriate DC coil suppression should be considered to control switching transients.
Typical Applications
- Industrial motor starters using 110 V DC control circuits.
- Three-phase motor switching applications.
- Industrial pumps and pumping stations.
- Heating, ventilation and air conditioning (HVAC) systems.
- Compressors, fans and ventilation equipment.
- Industrial machinery and manufacturing equipment.
- Conveyor systems and material handling machinery.
- Automated production and processing equipment.
- Electrical distribution and industrial power control panels.
- Power generators and backup generator auxiliary systems.
- OEM machinery and industrial electrical assemblies.
- Industrial automation systems requiring four normally open power poles.
