The Finder 62.33.8.012.4040 is a robust 16 A electromagnetic power relay designed for dependable switching in industrial automation, electrical control panels and power management systems. As part of the established Finder 62 Series, it combines three changeover contacts with a 12 V AC coil and durable silver tin oxide contacts.
This version includes a lockable test button and mechanical flag indicator, enabling engineers to operate the relay manually and identify its contact position during commissioning, maintenance and fault-finding. Its AgSnO2 contact material is cadmium-free and provides reliable switching performance for industrial electrical loads.
With a rated contact current of 16 A, a rated switching voltage of 250 V AC and a maximum switching voltage of 400 V AC, the 62.33.8.012.4040 is suitable for controlling contactors, solenoid valves, lighting, heating equipment and industrial machinery. Its plug-in format supports Finder 92 Series sockets or direct connection through Faston 187 terminals.
Electromagnetic power relays such as the Finder 62.33.8.012.4040 allow a low-voltage control circuit to operate several higher-current electrical circuits. Its three changeover contacts provide normally open and normally closed switching paths, supporting flexible control logic in machinery, process equipment and automation systems.
The dual-purpose test button can provide momentary manual operation or be locked in the operated position for testing. Combined with the mechanical flag indicator and durable AgSnO2 contacts, these features help engineers perform functional checks and maintain dependable switching performance.
