BF0022A048 - CONTROL RELAY 2NO+2NC 48V 50/60HZ

Why Choose the BF0022A048?

Meet the Lovato BF0022A048 control relay, engineered for dependable automation. This 4‑pole unit features an AC coil (50/60Hz) rated 48VAC and 2NO+2NC auxiliary contacts for versatile logic. Screw or 35mm DIN rail mounting streamlines panel assembly, and the BF00 series designation supports consistent specification. With Ui 690 V, Uimp 6 kV and Ith 10 A, it confidently handles industrial control duties and transient events.

Built for longevity and resilience, it delivers 20,000,000 mechanical cycles and operates from −50 to 70 °C, up to 3000 m altitude, pollution degree 3. Terminal connections are secure with 1.5 to 1.8 Nm tightening torque. Conformity to IEC/EN 60947-1 and 60947-5-1, plus UL and CSA counterparts, supports compliance across markets and harsh industrial environments.
