BF0040D012 - CONTROL RELAY 4NO 12VDC

Why Choose the BF0040D012?

Lovato’s BF0040D012 control relay is designed for AC and DC control circuits, pairing a 12 V DC coil with four normally open contacts for dependable multi-point switching. With 4 poles, Ui rated at 690 V and Uimp at 6 kV, it supports robust isolation and surge withstand, making it a solid choice for industrial panels and automation builds.

Installation is straightforward via screws or a 35 mm DIN rail, with terminal tightening torque of 1.5 to 1.8 Nm. Rated for -50 to 70 °C operation, up to 3,000 m altitude and pollution degree 3, it delivers a mechanical life of 20,000,000 cycles. Compliance includes IEC/EN 60947-1 and 60947-5-1, plus UL and CSA equivalents.
