Why Choose the Finder 62.32.8.120.4040 Industrial Power Relay?
The Finder 62.32.8.120.4040 is an industrial plug-in power relay with a 120 V AC coil, two changeover contacts (DPDT / 2 CO) and a lockable test button with mechanical operation indicator. Designed for electrical control panels, industrial machinery and automation systems, it combines the switching capabilities of the Finder 62 Series with practical features that simplify commissioning, inspection and maintenance.
Its two independent changeover contacts allow a single control signal to operate two separate circuits. Each pole provides normally open and normally closed switching paths, making the relay suitable for auxiliary control, electrical interlocking, load switching and machinery control functions. The silver tin oxide (AgSnO2) contact material is intended for demanding electrical switching duties, including appropriately rated applications where contact durability and inrush-current performance are important.
A distinguishing feature of the 4040 configuration is its lockable manual test button and mechanical flag indicator. These features allow engineers to check relay operation visually and manually during controlled testing. The plug-in design with Faston quick-connect terminals also supports installation in compatible Finder relay sockets, enabling the relay to be removed and replaced without desoldering. This makes the Finder 62.32.8.120.4040 a practical choice for industrial maintenance teams, control panel manufacturers and OEM equipment designers.

Reliable Changeover Switching with Manual Testing and Mechanical Indication
The Finder 62.32.8.120.4040 operates through an electromagnetic coil that controls two independent changeover contacts. When the 120 V AC coil is energised, each common contact transfers from its normally closed position to its normally open position. When the coil supply is removed, the relay returns to its normal state. This arrangement supports electrical interlocking, control logic, auxiliary switching and applications requiring a choice between two circuit paths.
The 4040 option adds a manually operated test button and a mechanical flag indicator. Under Finder's test-button arrangement, pressing the button operates the contacts, which return when the button is released. The locking function can be enabled by removing the designated plastic pip; the button can then be pressed and rotated to hold the contacts in their operated position until released. Manual testing should only be carried out under appropriately controlled electrical conditions because it can energise connected equipment independently of the normal control signal.

Frequently Asked Questions
What is the Finder 62.32.8.120.4040 used for?
The Finder 62.32.8.120.4040 is an industrial plug-in power relay used for switching electrical circuits in machinery, automation systems and control panels. Its two changeover contacts allow two independent circuits to be controlled by one coil, while the lockable test button and mechanical indicator assist with maintenance and commissioning.
What coil voltage does the Finder 62.32.8.120.4040 require?
The relay requires a nominal 120 V AC coil supply at 50/60 Hz. It is designed for compatible AC control circuits and should not be connected directly to a DC supply or a different nominal coil voltage.
What is the contact rating of the Finder 62.32.8.120.4040?
The Finder 62.32 series is a 16 A power relay platform. A distributor listing for this exact part number specifies 15 A, so the applicable contact rating should be confirmed against the manufacturer's current datasheet and the relevant electrical approval before final equipment selection. Permissible switching loads also depend on voltage, load type and operating conditions.
What is the difference between the Finder 62.32.8.120.4040 and 62.32.8.120.4030?
Both relays use a 120 V AC coil and a DPDT changeover contact arrangement. The 62.32.8.120.4040 features a lockable test button and mechanical operation indicator, while the 62.32.8.120.4030 provides an LED indicator for coil-status indication. The 4040 version is therefore useful where manual testing and mechanical indication are preferred.
How is the Finder 62.32.8.120.4040 installed?
The relay is designed for plug-in mounting using a compatible Finder relay socket. It features Faston 187 quick-connect terminals and can be installed in an appropriately specified control panel socket without soldering. Socket selection must account for the relay's contact arrangement, terminal layout and electrical ratings.
