BFT KUSTOS BT B40 Swing Gate Motor Kit

The KUSTOS BT B40’s ability to move 700 kg gate leaves using only 40W is the result of three factors working together. First, the 24V DC motor drives a precision worm gear with a high reduction ratio — converting fast low-torque motor rotation into slow high-force rod movement, multiplying the effective output force far beyond what 40W alone implies. Second, the 355mm rod actuator does not lift the gate — it pushes and pulls it along its hinge arc, so the hinge bears the gate’s vertical weight and the motor only overcomes horizontal inertia and friction. Third, the THALIA control unit with D-Track applies progressive power, ramping up force at gate startup (when inertia is highest) and modulating throughout the cycle. Compare this to the BFT ATHOS AC A25, which uses 280W for a gate rated at only 700 kg — the KUSTOS BT B40 achieves the same weight capacity at 85% less power consumption.

Yes — the BFT KUSTOS BT B40’s 700 kg per leaf rating is the highest weight capacity of any surface-mounted electromechanical swing gate motor in our range. For context: the KUSTOS BT A40 handles 500 kg, the BFT ATHOS AC A25 handles 700 kg (matching the B40 but at 280W and on a 2.5m leaf), the BENINCA BOB50M delivers 3500N thrust on 4.0m leaves, and the BENINCA DU.350N underground motor delivers 450Nm. The only product in our range with a higher gate weight rating is the BFT GIUNO ULTRA BT A50 hydraulic motor at 800 kg — but that is a hydraulic surface operator. The KUSTOS BT B40 is the heaviest electromechanical swing gate motor for surface mounting, made in Italy, running on 24V at just 40W.

The BFT KUSTOS BT B40 includes 2 x BFT MITTO2 COOL C4 remote controls. The MITTO2 designation indicates a 2-button body (two physical buttons on the handset), while the COOL refers to BFT’s updated design aesthetic, and C4 confirms 4 independently programmable channels accessible from the 2 buttons via button combinations. This means the remote can control up to 4 separate automation devices (a main gate, pedestrian gate, garage, and auxiliary) from a compact 2-button form factor. This differs from the B25’s MITTO COOL C4 (same 4 channels, 4-button body) and the A25’s MITTO2 B RCB (2-channel bidirectional). All use BFT’s rolling code encryption and pair directly to the THALIA control board’s built-in receiver.

For gates between 500 kg and 700 kg per leaf, the KUSTOS BT B40 is the more cost-effective and simpler choice — it is an electromechanical operator with no hydraulic oil, no oil maintenance intervals, and straightforward bracket installation. The BFT GIUNO ULTRA BT A50 hydraulic motor handles up to 800 kg and carries a very intensive use rating (the highest duty level), but requires Idrolux Winter hydraulic oil maintenance, a more complex piston mechanism, and a higher installation cost. If your gate leaves are confirmed at or near 700 kg, the KUSTOS BT B40 is the right fit. If they approach or exceed 700 kg, or if the site requires very intensive cycling beyond intensive use, the GIUNO ULTRA is the step up to consider.

The BFT KUSTOS BT B40 carries a 24-month manufacturer warranty from purchase and is made in Italy to BFT’s quality standards. For a motor rated at 700 kg per leaf on a 355mm stroke, gate hinge and post quality are especially critical — if the hinges are worn, misaligned, or undersized for a 700 kg leaf, the increased friction forces the motor beyond its D-Track load tolerance, causing repeated safety reversals that stress the actuator. Power surge protection on the 230V board supply is also strongly recommended to protect the THALIA control unit. The motor’s IP44 rating requires a sheltered installation away from direct water spray and concentrated dust.
