BF0004D220 - CONTROL RELAY 4NC 220VDC

Why Choose the BF0004D220?

Lovato BF0004D220 is a BF00 control relay for industrial control circuits, featuring a 220 VDC coil and four normally closed auxiliary contacts (4NC). With 4 poles and screw or 35 mm DIN rail mounting, it fits standard panels and cabinets. The compact relay offers straightforward integration where DC‑driven control and NC contact logic are required.

Engineered for durability and compliance, the relay delivers Ui 690 V, Uimp 6 kV and Ith 10 A performance, with a mechanical life rated at 20,000,000 cycles. It operates from -50 to 70 °C up to 3000 m altitude, pollution degree 3. Conforms to IEC/EN 60947-1 and -5-1, plus UL and CSA equivalents, supporting global panel standards.
