LA4FTE

The LA4FTE is a suppressor module from Schneider Electric’s TeSys F series, designed to protect the coil of compatible TeSys F contactors from the voltage spikes created when the coil is switched off. It uses a bidirectional peak-limiting diode to clamp transient voltage, helping protect sensitive control equipment such as PLC outputs, relays, and electronic controllers that share the same control circuit. Built for control circuits operating at {coil voltage}, it works on either AC or DC supplies, which makes it a flexible choice across a range of control panel designs. Electrically, the LA4FTE limits the transient voltage generated at the coil to a maximum of about 2.5 times the control circuit voltage, reducing the stress that switching surges place on nearby components. Because the diode design is bidirectional, it provides protection on both AC and DC coils within the 24 to 48 volt range. As a passive protection accessory, the LA4FTE does not switch or carry load current itself, and it works together with the contactor coil it is connected to. Mechanically, the LA4FTE is a compact module weighing roughly 0.04 kilograms that mounts by clips and connects to the coil screw terminals of the contactor. It is designed for TeSys F contactors, including the LC1F, LC2F, and CR1F families, and it clips onto the LA9D09981 mounting bracket, which is ordered separately. This makes the LA4FTE a quick, low-cost way to add coil surge protection to an existing TeSys F contactor installation or to a new panel build.
