Why Choose the Finder 62.33.8.110.4040 Power Relay?
The Finder 62.33.8.110.4040 is an industrial electromechanical power relay from the Finder 62 Series, designed for reliable switching in machinery, automation systems and electrical control panels. Featuring a 110 V AC operating coil and three changeover contacts (3CO / 3PDT), it enables three independent electrical circuits to be controlled through a single electromagnetic switching mechanism.
The Finder 62.33 relay configuration belongs to the manufacturer's 16 A power relay range, offering flexible switching for appropriately rated electrical loads. Its three-pole changeover arrangement provides normally open and normally closed contact paths, making it particularly useful for equipment sequencing, auxiliary control, signalling and applications requiring several circuits to operate together.
With its Faston 187 quick-connect terminal arrangement, the Finder 62.33.8.110.4040 is suited to industrial installations where practical wiring, secure connections and component replacement are important. The complete .4040 manufacturer variant designation should be retained when specifying replacements, as contact materials and optional relay features can differ between Finder 62 Series versions.

Reliable Three-Pole Switching for Industrial Control Systems
The Finder 62.33.8.110.4040 uses an electromagnetic operating mechanism to control three independent changeover contacts. When the specified 110 V AC coil supply is applied, the relay transfers its contacts from their normal positions to their energised positions. When the coil supply is removed, the monostable mechanism returns the contacts to their normal states.
The 3CO contact arrangement is especially useful where several electrical functions must operate in coordination. Each pole provides a common terminal and normally open and normally closed switching paths, enabling applications such as equipment sequencing, auxiliary interlocking and control-state signalling.
Using a single three-pole relay can simplify control circuit design where three separate switching functions must respond to the same command. The arrangement can also make electrical schematics and maintenance procedures more straightforward by keeping related switching functions within one identifiable component.
The relay's Faston 187 terminals provide a practical industrial connection method. When a socket is used, its terminal arrangement, electrical ratings and compatibility with the three-pole relay must be verified. A socket suitable for a two-pole Finder 62.32 relay should not automatically be assumed compatible with the three-pole Finder 62.33 configuration.
For dependable operation, the connected load's current, voltage, inrush characteristics and utilisation category must remain within the applicable relay ratings. Inductive loads, motors and equipment with high starting currents may require additional protective measures. The complete 62.33.8.110.4040 part number should be checked when selecting a replacement to ensure that the contact configuration and manufacturer-specific options match the installation.
