Reliable Four-Pole Switching for Lighting and Building Automation
The Finder 22.34.0.048.4320 modular contactor provides an effective way to control four electrical circuits from a single 48 V AC/DC command signal. When the coil is energised, all four normally open contacts close, allowing power to reach the connected loads. When the control voltage is removed, the contacts return to their open state.
This four-pole configuration is particularly useful in electrical distribution boards where several circuits must operate together. Examples include grouped commercial lighting, building services equipment and appropriately designed multi-circuit control installations. The contactor can also be incorporated into systems operated by compatible timers, automation controllers and low-voltage control interfaces.
The AgSnO2 contact material is a significant advantage for lighting applications because LED drivers and other electronic lighting equipment can produce high inrush currents during switch-on. However, the 25 A rating must not be treated as a universal LED load rating. Installers should check the manufacturer's applicable lamp-load limits, driver inrush characteristics and the total connected load before selecting the contactor.
The device's silent AC/DC coil is designed to reduce operating noise compared with conventional contactor designs. Its integrated varistor helps suppress voltage transients associated with coil switching, while the mechanical indicator and LED provide convenient visual feedback during commissioning and maintenance.
With a width of just 35 mm, the Finder 22.34 fits neatly into modular electrical distribution equipment. Its DIN rail mounting and screw terminals support practical installation, while reinforced insulation between the coil and contacts helps maintain electrical separation between the control and load circuits.
The contactor is designed for continuous-duty operation, making it suitable for installations where circuits remain energised for extended periods. Its IP20 rating means it should be mounted inside an appropriate electrical enclosure, with installation and protective devices selected according to applicable wiring regulations.
