40.31.8.230.0300

Power Relays, Over 2 Amps Overview

The Finder 40.31.8.230.0300 is a miniature PCB relay from the Series 40 range, designed for surface mount or plug-in applications with a 5.3 mm pin pitch. It features a 230V AC coil and silver nickel (AgNi) contacts configured as SPST-NO (1 Form A). The unit supports switching currents up to 10A at maximum voltages of 400V AC, handling loads up to 4000VA. Key electrical parameters include a 230V AC coil voltage and a 10A contact rating.

Power Relays, Over 2 Amps Feature Summary

• SPST-NO contact configuration utilizing silver nickel material for reliable switching performance
• Miniature form factor compatible with standard PCB layouts and socketable mounting options
• Designed for high-voltage switching capabilities within a compact industrial-grade enclosure

Power Relays, Over 2 Amps Applications

• Industrial control panel signal switching
• Automation equipment interface modules
• General purpose power distribution control

Power Relays, Over 2 Amps Procurement Notes

Verify the specific contact configuration against project requirements, as datasheets may list variations between SPST-NO and SPDT for similar part numbers. Confirm the coil voltage matches the control circuit exactly. Ensure the 5.3mm pin pitch aligns with the designated PCB footprint. Cross-reference the manufacturer's official documentation to confirm current availability and compliance status before finalizing procurement orders.

Power Relays, Over 2 Amps Selection Notes

Select this component when a single normally open contact is required for high-current switching in space-constrained designs. The 230V AC coil eliminates the need for additional driver circuits for mains-level control signals. Consider the AgNi contact material for durability under resistive loads. Evaluate the 5.3mm pitch against available board real estate compared to other series variants.

Power Relays, Over 2 Amps Part Context

This model belongs to the Finder Series 40, a line of miniature relays known for compact dimensions and versatile mounting options. The 40.31 sub-series specifically denotes a single-pole configuration with a 3.5mm to 5.3mm pin pitch variant. It serves as a direct replacement for older electromechanical switches in modern automated systems requiring robust isolation.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes include the 40.31.8.230.0000 if SPDT configuration is acceptable, or the 40.31.7.024.0000 for different coil voltages. Verify pin compatibility and contact form changes when substituting across the 40.31 family.
