40.52.8.024.0300

Power Relays, Over 2 Amps Overview

The Finder Relays Inc. model 40.52.8.024.0300 is a miniature electromechanical power relay designed for printed circuit board (PCB) mounting or plug-in applications. It features a double-pole single-throw normally open (DPST-NO) contact configuration, providing two Form A switching paths. The coil operates on 24VAC and draws 7.1 mA with a resistance of 3.35 kOhms. The contacts are rated for a maximum current of 8A and can switch voltages up to 400VAC, supporting a maximum switching load of 2400VA. Key electrical parameters include a 16.8 VDC minimum pick-up voltage, 5 ms operating time, and 3 ms release time. The unit utilizes silver-nickel (AgNi) contact material and offers high isolation capabilities.

Power Relays, Over 2 Amps Procurement Notes

Verify the specific ordering suffix to confirm the coil voltage type, as variations exist within the series. Ensure compatibility with standard Finder relay sockets if plug-in installation is required. Confirm RoHS compliance status and environmental certifications such as VDE or cURus for your target market. Cross-reference the pin pitch and mechanical dimensions against your PCB layout or enclosure constraints before finalizing procurement.

Power Relays, Over 2 Amps Selection Notes

Select this component when a DPST-NO configuration is necessary for 24VAC actuation. The 8A rating supports moderate power loads compared to lower-current alternatives. Consider the 5mm pin pitch for footprint planning. Evaluate thermal management requirements given the coil power consumption. This model serves as a direct replacement for older 40-series variants with matching contact and coil specifications.
