BF0004A04860 - CONTROL RELAY 4NC 48/60

Why Choose the BF0004A04860?

Designed for dependable signalling and interlocking, the Lovato BF0004A04860 is a control relay with an AC coil rated 48VAC at 60Hz and four normally-closed auxiliary contacts (4NC). It mounts quickly on 35mm DIN rail or with screws, simplifying panel integration. With a robust 10A Ith and Ui 690V / Uimp 6kV ratings, it delivers reliable performance across demanding industrial control circuits.

Built for longevity and harsh environments, this relay offers 20,000,000 mechanical cycles and operates from -50 to 70°C, up to 3000 m altitude, Pollution Degree 3. Terminal screws tighten to 1.5–1.8 Nm for secure connections. Conforming to IEC/EN 60947-1 and 60947-5-1 as well as UL and CSA equivalents, it suits safety-conscious, globally aligned control panels.
