Reliable Four-Pole Switching for Industrial and Building Automation

Modular installation contactors such as the Finder 22.44.0.024.4717 allow high-current electrical loads to be controlled through a separate operating circuit. When the 24 V AC/DC coil is energised, the internal electromagnetic mechanism closes the three normally open contacts and opens the normally closed contact. When the control supply is removed, the contacts automatically return to their normal positions, allowing conventional remote switching and control.

A distinguishing feature of the Finder 22.44 range is its mirror-contact construction. The normally closed monitoring contact is mechanically arranged to provide feedback associated with the state of the normally open power contacts. This is valuable in suitably designed safety-related control systems, where contactor feedback can be monitored by an external safety relay or controller. The contactor can be used as a switching component within such systems, but does not independently provide a complete safety function.

The Series 22 installation contactor design also incorporates an internal varistor protection circuit to reduce coil switching transients, mechanically indicated contact positions and reinforced insulation between the control and load circuits. These features make the Finder 22.44.0.024.4717 a practical choice for electrical installers, industrial automation engineers and control panel builders.
