Reliable 24 V AC Control for Industrial Motor Switching

The Finder 6K.14.8.024.4710 enables a compatible 24 V AC control circuit to operate electrical loads through an electromagnetic switching mechanism. When the coil is energised, the three normally open contacts close and the normally closed contact opens. When the coil supply is removed, the contacts return to their normal positions.

This contact arrangement is useful where an installation requires three normally open switching paths together with a complementary normally closed circuit. The contactor can be incorporated into suitably designed motor starters, machine control systems and electrical switching assemblies.

The 4 kW AC-3 motor rating at 400 V AC makes the Finder 6K.14.8.024.4710 suitable for appropriately rated three-phase motors. The actual motor selection must account for rated current, starting characteristics, switching frequency and environmental conditions.

Understanding AC-3 and AC-1 Switching Ratings

The AC-3 utilisation category covers specified motor switching duties, including starting and switching off suitable squirrel-cage motors during normal running conditions. The Finder 6K.14.8.024.4710 has a 4 kW AC-3 motor rating at 400 V AC, making it appropriate for selected industrial motors in pumps, fans and machinery.

The separate 25 A AC-1 rating applies to suitable non-inductive or slightly inductive loads. AC-1 and AC-3 ratings are not interchangeable because motor starting currents and inductive interruption impose different demands on the contactor contacts. All connected circuits, including the normally closed pole, must remain within their applicable manufacturer ratings.

Compact DIN Rail Installation and Electrical Protection

The Finder 6K.14.8.024.4710 is designed for convenient DIN rail mounting within industrial electrical control panels. Its 45 mm-wide housing helps conserve installation space, while its screw terminal connections support secure wiring using suitable conductors with cross-sections from 0.75 to 6 mm².

The contactor has an IP20 protection rating and should be installed inside an appropriately designed electrical enclosure. For motor control applications, suitable overload and short-circuit protective devices must be selected according to the motor, circuit characteristics and applicable coordination requirements. The stated 10 kA short-circuit specification is conditional on the appropriate protective arrangement and does not mean that the contactor can independently interrupt a 10 kA fault.
