Finder 45.71.7.048.1310 PCB Power Relay 48 V DC 16 A 1 NO

When a control circuit needs to switch a high-current AC load from a low-power DC signal, a compact PCB relay is often the answer. The Finder 45.71.7.048.1310 is a PCB power relay with a 48 V DC coil and a single normally open contact rated for 16 A at 250 V AC. It is part of the Finder Series 45, designed for direct mounting on printed circuit boards.

Who is it for

This relay suits engineers and technicians building or repairing industrial controls, HVAC systems, appliance controls, and other electronic devices that require reliable switching of moderate AC loads. Its reinforced insulation and flux-proof construction make it appropriate for use in demanding environments.
