Finder 65.31.8.125.4300 – 65 Series Power relays

Why Choose the Finder 65.31.8.125.4300 Power Relay?

The Finder 65.31.8.125.4300 is an industrial electromechanical power relay from the Finder 65 Series, designed for dependable switching in machinery, electrical control panels and automation equipment. Featuring a 125 V AC operating coil and a normally open contact configuration, this relay is suited to applications where a control signal must operate a separate electrical load.

The relay's normally open switching action keeps the load circuit open when the coil is de-energised and closes the contact when the appropriate control voltage is applied. Its wide-contact-gap configuration provides increased physical separation between open contacts, making it useful for appropriately designed control and load-switching systems.

As part of Finder's industrial power relay range, the 65.31.8.125.4300 offers a practical solution for machine builders, electrical engineers and maintenance professionals seeking an AC-operated relay for switching suitable loads. Its installation, wiring and load selection should follow the manufacturer's technical documentation for this exact variant.

Key Advantages

Reliable Electrical Switching for Industrial Automation

The Finder 65.31.8.125.4300 operates using a 125 V AC control signal. When the coil is energised, its electromagnetic mechanism closes the normally open contact, allowing current to flow through the connected load circuit. When the coil supply is removed, the relay returns to its de-energised state and the contact opens.

The single-pole normally open arrangement makes this relay useful for control systems where an electrical circuit should only be completed when an appropriate command is present. Its wide-contact-gap construction provides increased physical separation between open contacts. This feature does not, by itself, establish suitability for safety isolation; any safety-related application must be assessed against the relay's certifications and the complete equipment design.

When specifying the Finder 65.31.8.125.4300, engineers should confirm the exact contact rating, switching category, mounting arrangement and terminal configuration against the manufacturer's documentation. This is especially important for motors, inductive loads, high-inrush equipment and DC switching applications, where permissible switching values can differ substantially from resistive AC ratings.
