FINDER 40.31.9.048.0000 PCB/steekrelais 48V AC 1 CO 10A

When a control system must switch a 10 A load with a 48 V AC coil, the FINDER 40.31.9.048.0000 delivers reliable single-pole changeover switching in a compact, flux-proof package. This relay fits both PCB and plug-in sockets, making it a flexible choice for industrial and building automation panels.

Who is it for

Panel builders and maintenance engineers who need a proven SPDT relay for general-purpose switching of resistive or inductive loads up to 2500 VA. Its 48 V AC coil suits control circuits with that voltage, while the AgNi contact material handles moderate inrush currents.
