40.52.8.024.0000

Power Relays, Over 2 Amps Overview

The Finder Relays Inc. model 40.52.8.024.0000 is a general-purpose power relay from the 40 Series, designed for through-hole mounting on printed circuit boards. It features a double-pole double-throw (DPDT) contact configuration with two Form C contacts. The coil operates at 24 VAC and draws 7.1 mA, with a resistance of 3.35 kOhms. The contacts are rated for a maximum switching voltage of 400 VAC and a current of 8 A, supporting loads up to 2400 VA. Constructed with silver-nickel (AgNi) contacts, it functions within an ambient temperature range of -40°C to +85°C.

Power Relays, Over 2 Amps Feature Summary

• Features a DPDT contact arrangement providing two independent Form C switching paths for complex control logic.
• Utilizes a sealed construction with flux protection to ensure reliability in harsh industrial environments.
• Employs silver-nickel contact material to enhance durability and electrical conductivity under load.

Power Relays, Over 2 Amps Applications

• Industrial automation control panels
• HVAC system management circuits
• General purpose PCB signal switching

Power Relays, Over 2 Amps Procurement Notes

Verify that the specific order matches the 24 VAC coil requirement, as this variant differs electrically from DC coil versions within the same series. Confirm the DPDT contact configuration aligns with the target circuit design. Ensure compatibility with standard socketing if plug-in installation is required. Check for RoHS compliance status relevant to the manufacturing batch.

Power Relays, Over 2 Amps Selection Notes

Select this component when a dual-circuit switching solution is required on a single PCB footprint. The 24 VAC coil specification dictates the necessary driver circuitry. Consider the 8 A current rating for moderate power loads. The wide operating temperature range supports deployment in uncontrolled environmental conditions.

Power Relays, Over 2 Amps Part Context

This unit belongs to the Finder 40 Series, a line of compact power relays intended for PCB integration. The series offers various coil voltages and contact configurations. This specific part number represents the AC coil variant with high-current capacity, distinguishing it from lower-amperage or DC-operated siblings in the product family.

Power Relays, Over 2 Amps Replacement Considerations

Direct substitutes include other 40 Series models with identical DPDT contacts and 24 VAC coils, such as 40.52.7.024.0000 variants if pinout compatibility is verified. Cross-series replacements require validation of mechanical dimensions and electrical ratings against the original design specifications.
