Why Choose the Lovato BF38T2A024 Four-Pole Power Contactor?
The Lovato BF38T2A024 is a versatile four-pole power contactor with two normally open and two normally closed contacts, designed for industrial switching and control applications. Part of the Lovato BF38 series, it provides dependable operation for circuits requiring simultaneous switching with complementary contact states.
The contactor has an IEC conventional free-air thermal current rating of 56 A and an AC-3 operational current rating of 38 A at up to 440 V and 55 °C. Its four-pole 2NO+2NC configuration supports specialised control, changeover and load-switching arrangements.
A 24 V AC 50/60 Hz control coil makes the BF38T2A024 suitable for common low-voltage industrial control circuits. Screw or 35 mm DIN-rail mounting, IP20 power-terminal protection when properly wired and a long mechanical life support reliable installation in machinery and electrical panels.

Flexible Four-Pole Switching for Industrial Control
The BF38T2A024 uses two normally open and two normally closed power contacts that change state when its 24 V AC coil is energised. This complementary arrangement enables multiple circuits or loads to be switched simultaneously without requiring separate contactors for each contact state.
Its high thermal-current rating, durable construction and long operating life make it suitable for industrial power and control assemblies. The compact BF38 format also supports straightforward integration into machine panels, distribution boards and specialised switching systems.
Typical Applications
- Complementary load-switching circuits.
- Industrial control and automation panels.
- Changeover and transfer-control assemblies.
- Heating, lighting and resistive-load control.
- Manufacturing and processing machinery.
- Electrical panels using 24 V AC control circuits.
