BF0040A57560 - CONTROL RELAY 4NO 575/60

Why Choose the BF0040A57560?

Lovato’s BF0040A57560 control relay delivers dependable switching for control circuits with an AC coil rated 575 VAC at 60 Hz. Featuring four normally open contacts across four poles, it integrates cleanly into panels via screw fixing or 35 mm DIN rail mounting. The design supports precise signalling and interlocking, helping streamline panel layouts while maintaining clear status control across auxiliary circuits.

Engineered for reliability, this control relay offers Ith 10 A, Ui 690 V and Uimp 6 kV, backed by a mechanical life of 20,000,000 cycles. It operates from −50 to 70 °C, up to 3000 m altitude, Pollution Degree 3, with terminal tightening torque 1.5–1.8 Nm. Conformity to IEC/EN 60947-1 and 60947-5-1, plus UL and CSA equivalents, supports compliance in demanding installations.
