40.52.8.240.0000

Power Relays, Over 2 Amps Overview

The Finder Relays Inc. model 40.52.8.240.0000 is a miniature electromechanical relay from the 40 Series, designed for general-purpose applications. It features a double-pole double-throw (DPDT) contact configuration with an 8A rated current capacity and a maximum switching load of 2400VA. The coil operates at 240V AC, consuming approximately 1.5W of power. Key electrical parameters include a maximum contact voltage of 400VAC and a coil resistance of 32 kOhms. The device utilizes silver-nickel (AgNi) contacts and offers high isolation capabilities with 6kV dielectric strength between coil and contacts, alongside 8mm creepage and clearance distances. It supports both PCB mounting and plug-in base installation.

Power Relays, Over 2 Amps Procurement Notes

Verify that the specific order matches the 40.52.8.240.0000 designation, ensuring the 240V AC coil voltage and DPDT configuration are correct for your application. Confirm compatibility with standard 5mm pin pitch plug-in bases if not using direct PCB soldering. Check for RoHS compliance status as per current manufacturer declarations. Ensure handling procedures respect the mechanical life specifications during integration testing.

Power Relays, Over 2 Amps Selection Notes

Select this component when a DPDT configuration is required for 240V AC control circuits. The 8A rating makes it suitable for moderate power loads compared to lower-current series options. Consider the 5mm pin pitch for board layout constraints. Evaluate the need for plug-in versatility versus permanent PCB mounting. Compare against the 40.31 series if single-pole functionality suffices, or the 40.51 series for different pin spacing requirements.

Power Relays, Over 2 Amps Part Context

This relay belongs to the Finder 40 Series, a range of miniature electromagnetic relays known for their small volume and high performance. The 40.52 sub-series specifically denotes a two-pole variant with an 8A current rating and 5mm pin pitch. This series is widely used in industrial automation and building management systems where space efficiency and reliable switching are critical. The 40.52.8 suffix indicates the DPDT contact form and 240V AC coil specification.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes within the same family include other 40.52 variants with different coil voltages such as 40.52.8.024.0000 (24V DC) or 40.52.8.110.0000 (110V AC). Cross-series replacements like the Finder 55 series offer similar functionality but may differ in physical dimensions and pinout. Verify that any alternative maintains the 8A contact rating and DPDT configuration to ensure circuit compatibility without redesigning the PCB or wiring harness.
