Description

The SF4D-DC12V is a power relay designed for high contact reliability. It features a double contact mechanism and forced operation contacts that are connected through a card to prevent contact welding. The independent operation contacts (4 Form A 4 Form B) ensure that if a pair of contacts are welded, the other contacts remain unaffected. The relay has a separated chamber structure to prevent short circuits between contacts, high breakdown voltage, and high sensitivity. It complies with safety standards and is certified by UL, CSA, TÜV, and SEV.
