3TM3431-1WA20-0AD2-Z F20+F23

The 3TM3431-1WA20-0AD2-Z F20+F23 is a three-pole vacuum contactor designed for medium voltage applications, offering reliable switching performance and robust construction. It features a rated voltage (Ur) of 12kV, withstanding a Basic Impulse Level (BIL) of 75kV and a Power Frequency Withstand Voltage (PFWV) of 28kV, ensuring insulation integrity under demanding conditions. The contactor is capable of handling a rated normal current (Ir) of 450A, suitable for controlling motors, transformers, and other inductive loads. Its rated short-circuit breaking current (Isc) is 5kA for 1 second without fuses, providing protection against fault currents. The controller operates with a standard magnet coil voltage of 220-250V DC or 230-240V AC, offering flexibility in power supply options. This model does not include a latching/delatching system, and it cannot be retrofitted with one. The pole-center distance is 120mm, facilitating installation in standard switchgear panels. It has no additional closing time and release voltage without a delatching system. Auxiliary contacts include 6 normally open (NO) and 6 normally closed (NC) contacts, providing versatile signaling capabilities. An operating manual in English is included for comprehensive guidance.
