Why Choose the BF0040L048?
Lovato's BF0040L048 is a panel-ready control relay designed for dependable automation switching. Featuring a low-consumption 48VDC coil and four normally open contacts, this 4-pole unit fits screw or 35mm DIN rail mounting. It delivers a rated insulation voltage of 690 V and impulse withstand of 6 kV, supporting robust performance across control circuits where efficient DC coil operation and clean contact closure are essential.
Built on the BF00 platform, it is rated Ith 10 A and tested for 20,000,000 mechanical cycles, providing long service in demanding panels. Operating from -50 to 70 °C and up to 3000 m altitude, with Pollution Degree 3 robustness, it meets IEC/EN 60947-1 and 60947-5-1, plus UL 60947-1, UL 60947-5-1 and CSA C22.2 n° 60947-1 / 60947-5-1. Terminals accept 1.5 to 1.8 Nm tightening for secure wiring.
