Technical note: The specifications above reflect the Finder 62.33 relay family and the configuration indicated by the part number. The exact 4030 suffix characteristics, coil resistance, optional equipment and approvals should be confirmed against the manufacturer's product-specific documentation before final engineering selection.
Reliable Three-Pole Switching for Industrial Automation
The Finder 62.33.8.230.4030 enables three electrical circuits to be controlled through a single 230 V AC operating coil. When the coil is energised, the relay's electromagnetic mechanism transfers all three changeover contacts from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts return to their original positions, providing repeatable switching for industrial control systems.
The 3PDT contact arrangement offers greater flexibility than a normally open-only relay because each contact set can be used to select between two circuit paths. This makes the Finder 62.33.8.230.4030 suitable for control logic, signalling, equipment interlocking and switching applications where several electrical functions must operate together.
As part of the Finder 62 Series, this relay combines high-current contact capability with a serviceable plug-in design. Installation with a compatible Finder 92 Series socket allows convenient relay replacement without extensive rewiring, helping simplify maintenance in industrial electrical panels and machinery.
Typical Applications
- Industrial machinery and automated production equipment.
- Electrical control panels and switching assemblies.
- PLC-controlled automation interfaces.
- Three-circuit changeover switching and signalling.
- Industrial heating and temperature control equipment.
