BF0040D024 - CONTROL RELAY 4NO 24VDC

Why Choose the BF0040D024?

The Lovato BF0040D024 control relay brings dependable auxiliary switching to 24 V DC control circuits. Featuring a DC coil and four normally-open contacts (4NO), this BF00-designated device suits panel builders needing compact, versatile control relays. It installs quickly via screw fixings or on a 35 mm DIN rail, streamlining panel assembly and maintenance.

Engineered for demanding environments, it offers Ui 690 V, Uimp 6 kV and Ith 10 A, with a mechanical life of 20,000,000 cycles. Rated for -50 to 70 °C operation and up to 3000 m altitude (pollution degree 3), it meets IEC/EN 60947-1 and 60947-5-1, plus UL and CSA equivalents, supporting safe, standards-compliant integration.
