The Lovato BF26T4A02460 is a compact and robust four-pole power contactor designed for industrial load switching, control panels, machinery and automation systems. Part of the Lovato Electric BF contactor range, it provides dependable switching performance with a 4 normally open contact configuration.
This BF26 contactor has an IEC conventional thermal current Ith of 45 A in AC-1 duty and an IEC AC-3 operating current of 26 A at up to 440 V, making it suitable for resistive loads, lightly inductive loads and selected motor switching applications. Its 24 V AC 60 Hz coil is designed for low-voltage AC control circuits used in machine control, HVAC panels, industrial distribution and OEM electrical assemblies.
The BF26T4A02460 is designed for straightforward installation using screw fixing or 35 mm DIN rail mounting. With recognised international approvals, IP20 terminal protection when correctly wired, long mechanical life and compatibility with Lovato BF series accessories, it is a practical choice for professional panel builders requiring a four-pole normally open contactor.
The Lovato BF26T4A02460 provides four normally open main poles that close together when the 24 V AC 60 Hz coil is energised. This configuration is suitable for switching multiple lines or circuits from one coil command, subject to the required protection, load category and installation design.
With its 45 A AC-1 rating, 26 A AC-3 operating current, IP20 terminal protection and compact BF26 frame, the BF26T4A02460 is well suited to machine control panels, HVAC systems, automation assemblies and OEM equipment where a reliable four-pole normally open contactor is specified.

The Lovato BF26T4A02460 is used for industrial switching applications where a four-pole contactor with 4 normally open contacts and a 24 V AC 60 Hz control coil is required.
The BF26T4A02460 has 4 poles, arranged as 4 normally open main contacts.
It has an IEC conventional thermal current Ith AC-1 rating of 45 A and an IEC AC-3 operating current rating of 26 A at up to 440 V.
The BF26T4A02460 uses a 24 V AC coil designed for 60 Hz control circuits.
At 60 Hz, the coil consumes approximately 75 VA inrush and 9 VA holding.
The contactor can be mounted by screw fixing or on a standard 35 mm DIN rail inside an electrical control panel.
4NO means the contactor has four normally open contacts. These contacts are open when the coil is not energised and close when the coil is energised.
Lovato BF series contactors are widely used by electrical engineers, OEMs and panel builders for reliable switching, compact installation and professional integration into industrial control systems.
