Why Choose the Finder 6K.04.9.012.4812 Industrial Contactor?
The Finder 6K.04.9.012.4812 is a compact, four-pole industrial mini contactor designed for reliable motor control, electrical load switching and industrial automation applications. Part of the Finder Series 6K, this model features a 12 V DC operating coil, three normally open main contacts and one additional normally open auxiliary contact, providing flexible switching functionality within a compact DIN rail-mounted housing.
Featuring a 12 A AC-3 operational current rating at 400 V AC and a 5.5 kW three-phase motor power rating, the Finder 6K.04.9.012.4812 is suitable for appropriately rated motor switching applications. Its 3 NO + 1 NO contact configuration enables three-phase power switching alongside an auxiliary signalling or control function. The auxiliary contact has its own electrical rating and is not intended to carry the same load as the three main contacts.
With silver tin oxide (AgSnO2) contacts, 35 mm DIN rail mounting and a compact 45 mm-wide design, this Finder mini contactor offers a practical solution for industrial electrical panels where space, installation efficiency and dependable operation are important. It is particularly suited to machinery, pump controls, HVAC equipment, motor starters and OEM automation systems using low-voltage DC control circuits.

Reliable 12 V DC Control for Three-Phase Motor Switching
The Finder 6K.04.9.012.4812 enables a low-voltage 12 V DC control circuit to operate three-phase electrical loads through an electromagnetic contactor. When the coil is energised, the three normally open main contacts close, allowing the connected power circuit to operate. The additional normally open auxiliary contact closes at the same time and can be incorporated into a suitably rated feedback, signalling or control circuit.
The Finder Series 6K.04 is designed for compact industrial motor switching applications. Its AC-3 rating reflects a motor utilisation category rather than a general-purpose current rating, making it important to select the contactor according to motor characteristics, switching frequency and operating conditions. The integrated auxiliary contact must also be assessed separately, particularly where inductive control loads are involved.
For reliable installation, the Finder 6K.04.9.012.4812 should be used with appropriately selected motor overload protection, short-circuit protection and a suitable 12 V DC coil supply. Its compact DIN rail construction makes it suitable for incorporation into industrial control panels alongside motor protection devices, terminal blocks and automation equipment.
Typical Applications
- Industrial motor starters using 12 V DC control circuits.
- Three-phase motor switching and control.
